Važno je to razumjeti prije nego što nastavimo dalje. Baš kao što posjećujemo salon kako bismo modificirali svoj izgled i postali trendi. Slično, trebate oblikovati hardverske mogućnosti svojih osobnih računala. Morate biti svjesni najboljih operativnih sustava^(Systems) dostupnih za korištenje danas. No, trebali biste se zadržati i na najgorim operativnim sustavima kako biste se spasili od sporih ili oštećenih računala. Donosimo vam popis najboljih neuspjelih operativnih sustava u ovom članku.

Top 10 najgorih operativnih sustava^{(Top 10 Worst Operating Systems)}

Općenito skraćeno OS , Operativni sustav^{(Operating System)} upravlja podacima sustava i djeluje kao sučelje između hardvera i softvera računala. Jednostavno^(Simply) rečeno, djeluje kao medij komunikacije za osobu koja upravlja računalom i samim strojem. Operativni sustavi^(Systems) se mogu podijeliti na:

• Računalni operativni sustavi opće namjene
• Mobilni operativni sustavi u stvarnom vremenu.

Razgovarajmo sada o 10 najgorih operativnih sustava^(Systems) svih vremena pojedinačno. 

1. MS-DOS 4.0

Vlasnički proizvod Microsofta razvijen 1986.^{(developed in 1986)} godine, pušten je na tržište 1988. godine. U usporedbi s ranijim verzijama, označen je kao pokvareno jaje Microsoftove^(Microsoft) košarice iz razloga navedenih u nastavku:

• Jednostavno bi prestao djelovati u sredini, niotkuda.
• Nije mogao obavljati više zadataka; dakle, izvodio bi samo jedan program u isto vrijeme 
• Zbog svoje nemogućnosti obavljanja više zadataka^{(inability to multitask)} , bio je neprikladan za aplikacije na radnim stanicama
• Ovaj je OS bio vrlo ovisan o korisniku^{(highly user-dependent)} . Stoga se ne može koristiti u slučaju da je korisnik zaboravio njegove naredbe. 
• Novim korisnicima bilo je teško zapamtiti sve naredbe. To ih je natjeralo da se odmaknu od ovog softvera. 
• Suočio se s poteškoćama u pristupu RAM- u s više od 640 MB prostora za pohranu.
• Nije prihvatio naredbu automatskog zahtjeva za prekidom (IRQ)^{(Interrupt Request (IRQ) command)} . Dakle, korisnik nije mogao pokrenuti nijedan novi program dok je program koji je već pokrenut stavio na čekanje.

2. Windows ME

Windows ME ili Millennium Edition of Windows bio je vlasnički softver tvrtke Microsoft pokrenut u rujnu 2000. godine^{(launched in September 2000)} . Imao je sljedeće nedostatke:

• Budući da je pun bugova, postao je vrlo nestabilan sustav. 
• Značajke poput vraćanja sustava i instalacije programa bile su potpuna katastrofa^{(System Restore & Program Installation were a complete disaster)} jer su ponovno instalirale već izbrisane viruse na računalo.
• To ga je učinilo vrlo sporim, nesigurnim i nestabilnim sustavom^{(slow, insecure, and unstable system)} .
• Parametri sustava^(System) nekih uređaja nisu podržavali unaprijed instalirani hardver.
• Često pomicanje miša nakon povratka na posao nakon malih pauza, rezultiralo je padom sustava Windows ME .
• Drugi razlog bio je taj što je njegova upotreba bila ograničena samo^{( usage was limited)} na kućne korisnike.
• Ovaj OS nije bio dostupan na otvorenom tržištu. 
• Nedostatak sigurnosnih ažuriranja bio je još jedan veliki problem s ovim softverom.
• Pokušavajući funkcionirati kao oba, 16-bitni i 32-bitni OS^{(16-bit & 32-bit OS)} doveli su do više kaosa u svom radu umjesto da ga poboljšaju.
• Glavni razlog njegovog neuspjeha bilo je povlačenje podrške od strane^{(withdrawal of support by Microsoft)} samog Microsofta. 
• Lansiranje sustava Windows XP , samo u roku od godinu dana od objavljivanja ovog softvera, pokazalo se kobnim udarcem.

3. Windows Vista

Windows Vista je objavljen u mjesecu studenom 2006. godine^{(month of November in 2006)} , nakon izdavanja sustava Windows XP , njegovog moćnog prethodnika. Očito se moralo jako pomučiti kako bi steklo ime na tržištu. Nažalost, nije mogao graditi na svojoj reputaciji i označen je kao među deset najgorih operativnih sustava svih vremena. Evo zašto:

• Ovaj softver je bio sklon nadimanju^(bloating) tj. usporavanju programa. 
• Također je zauzimao veći memorijski prostor zbog brojnih predinstaliranih programa i dodavanja neželjenih novih značajki postojećim programima. To je poznato kao softversko puzanje.
• Takvo puzanje softvera^{(software creeping)} činilo ga je zbunjujućim i ponekad teškim za korištenje ovog neuspjelog operativnog sustava.  
• Postojala je loša kompatibilnost^{(poor compatibility)} između hardvera i softvera. Na primjer, Windows 7 nije kompatibilan sa sustavom Windows Vista^{(Windows Vista)} . Dakle, obično se oboje ne mogu koristiti istovremeno, na istom računalu, zbog različitih hardverskih zahtjeva. Stoga je sustav Windows Vista^{(Windows Vista)} zahtijevao samo računala kompatibilna sa sustavom Vista.
• Iz sigurnosnih razloga dopušta samo instalaciju ^{(only allowed the installation of)} potpisanih upravljačkih programa^{(signed drivers)} . To je značilo da bi razvojni programer trebao dobiti certifikat Authenticode od ^{(Authenticode)}Microsofta^(Microsoft) . Ova je certifikacija bila vrlo skupa i nedostižna za manje programere bez robne marke.
• Cijene^(Pricing) su bile još jedan problem s ovim softverom jer je za većinu ljudi bio vrlo skup.
• Ovaj OS nije dopuštao određene programe kao što je Android Package Kit za instalaciju mobilnih aplikacija, mobilnih igara, Aero inženjering, Windows Movie Maker verzije itd.
• Loš marketing^{(Poor marketing)} ovog operativnog sustava postao je još jedan uzrok njegovog lošeg rangiranja.

4. Windows 8/8.1

S idejom da se unesu velike promjene u korisničko sučelje, ovaj softver je lansiran 2012. godine^{(launched in the year 2012)} . Microsoft je shvatio da ljudi više ne rade na jednom uređaju, tj. osobnom računalu; umjesto toga, koristili su razne uređaje poput prijenosnih računala, tableta, telefona itd. Stoga je Windows 8 uveden kako bi zadovoljio zahtjeve više uređaja^{(Windows 8 was introduced to cater to the requirements of multiple devices)} . Nije uspio postići svoj cilj jer:

• Ukidanje gumba za ^{(discontinuation of the)} pokretanje^{(start button)} bila je krajnje zbunjujuća značajka ove verzije.
• Nije odgovarao potrebama kućnog računala jer su korisnici postajali sve više zbunjeni i frustrirani nego opušteni.
• Onemogućio je dizanje^{(disabled booting)} tj. proces pokretanja računala ili desktopa. Umjesto toga, omogućio je dizanje početnog zaslona, ​​ostavljajući korisnike opet zbunjenima.
• Naposljetku, Microsoft je morao vratiti gumb Start^{(Microsoft had to restore the Start button)} na radnu površinu kako bi izbjegao sve nepoželjne gužve.
• Većina aplikacija u ovom OS -u nije mogla raditi na više platformi^{(unable to work cross-platform)} i bila je funkcionalna samo u sustavu Windows 8^{(Windows 8)} .
• Trebalo je potražiti ikonu pretraživanja^{(search for the search icon)} , da biste pokrenuli bilo kakvu pretragu na vašem računalu.
• Ova se značajka mogla lako postaviti na radnu površinu i ova se nevolja mogla u potpunosti izbjeći.
• Windows 8 zahtijevao je obuku^{(required training)} zaposlenika tvrtke za korištenje ovog softvera u organizaciji. To je rezultiralo ne samo neželjenim troškovima obuke već i gubitkom produktivnosti zaposlenika. Bilo je potrebno više vremena, truda i novca za upoznavanje netehničkih korisnika s ovim softverom, stvarajući više štete nego koristi za spomenutu organizaciju. 
• Nadogradnja na ovaj sustav uključivala je promjenu upravljačkih programa^{(change of drivers)} na perifernim uređajima spojenim na računalo. Stoga^(Hence) su svi uređaji kao što su pisači, mikrofoni, zvučnici, kamere itd. zahtijevali nove upravljačke programe, što je povećavalo troškove sustava, čak i više.
• Da biste pozvali udaljenog zvučnika pomoću prijenosnog računala sa sustavom Windows 8^{(Windows 8)} , daljinski mikrofon zahtijevao je promjenu kompatibilnog upravljačkog programa. To je često činilo korištenje udaljenih sastanaka neizvedivim^{(remote meetings unfeasible)} .
• Situacija sa sindromom podijeljenog mozga nastala je u uredu koji koristi sustave Windows 8. To može dovesti do oštećenja ili nedosljednosti podataka^{(data getting corrupt or inconsistent)} .
• Windows 8 rezultirao je nedostatkom učinkovite razmjene informacija među različitim zaposlenicima u organizaciji i raznim korisnicima diljem svijeta.

S obzirom na gore navedene nedostatke, Microsoft je izdao Windows 8.1 u listopadu 2013.^{(October 2013)} , godinu dana nakon izdavanja sustava Windows 8 . Window 8.1 popravio je postojeće nedostatke prevladavši nedosljednosti u sustavu Windows 8^{(Windows 8)} i omogućio korisnicima učinkovitije funkcioniranje. Iako se i od toga brzo odustalo u korist Windowsa 10^{(Windows 10)} .

5. Prozor 1.01^{(5. Window 1.01)}

Riječ je o Microsoftovom^(Microsoft) zatvorenom izvornom kodu, grafičkom korisničkom sučelju, a ne komercijalnom softveru za DOS sučelje naredbenog retka. Iako je najavljeno da će biti objavljen u studenom 1983.^{(November 1983)} , konačno je objavljen kao dodana verzija MS-DOS-a u studenom 1985. godine^{(released as an added version of MS-DOS in November 1985)} . Uvršten je na popis 10 najgorih operativnih sustava svih vremena iz sljedećih razloga:

• Njegovo loše dizajnirano korisničko sučelje^{(poorly designed user interface)} nije moglo zadovoljiti specifične potrebe potrošača.
• Njegov iznenadni kolaps usred programa koji se izvodi pokazao je njegovu lošu obradivost^{(poor workability)} . Ovo je samo dolilo ulje na vatru.
• Kašnjenje s uvođenjem ovog sustava od dvije godine dodatno je uzrokovalo njegov pad.
• Dostupnost daleko superiornijeg Mac 2.1 OS^{(superior Mac 2.1 OS)} - a koji je uključivao  AppleTalk umrežavanje, PostScript ispis s laserskim pisačem i sofisticirani PC-bazirani hijerarhijski datotečni sustav^{(Hierarchical File System)} nadjačala je njegove značajke. Slijedom toga, Microsoft nije mogao izazvati veliko zanimanje korisnika za Windows 8 u vrijeme njegovog lansiranja. 
• Njegov naglasak na korištenju unosa mišem^{(use of mouse input)} za kontrolu korisničkog sučelja u to vrijeme nije bio široko rasprostranjen. Bilo je izvan razumijevanja korisnika i stoga nije mogao prikupiti bazu obožavatelja.
• Njegova usklađenost ne-Y2K^{(non-Y2K compliance)} zajedno s nižim ^(lower) hardverskim specifikacijama^{(hardware specifications)} rezultirala je problemima s performansama.
• Njegova ograničena dostupnost resursa^{(limited resource availability)} nije mogla izazvati željeni interes i/ili impresionirati nove korisnike Windowsa^(Windows) .

6. Corel Linux

Od tri glavna OS za računala, odnosno Windows , Mac i Linux , o Linuxu^(Linux) se najmanje govori o operativnom sustavu otvorenog koda koji nije uspio. Linux je kreirao Debian i izašao je na otvoreno tržište u studenom 1999. godine^{(released in the open market in November of 1999)} . Reklamirano je da se konačno zaustavi monopol Microsofta^(Microsoft) , ali nije uspjelo jer:

• Njegovo kasno izdanje^{(late release)} i postojeća dostupnost drugih operativnih sustava kao što su Microsoft Windows 98, Windows 2000 i Apple Mac OS 9 , nisu mu pomogli da stekne popularnost.
• Za razliku od Windowsa^(Windows) i Maca^(Mac) , koji su imali mnogo određenih verzija, Corel Linux nije imao standardno izdanje^{(had no standard edition)} . Uz stotine korisnički razvijenih izdanja koja plutaju na tržištu, postalo je vrlo izazovno odabrati najbolje. Ova zbrka je odvratila nove korisnike da ga prihvate.
• Proces instalacije ovog OS-a bio je ^{(installation process of this OS was)} vrlo naporan^{(very cumbersome)} , pa je instalacija novih programskih datoteka od strane novih korisnika bila maraton.
• U većini slučajeva instalacija ovog softvera nije uspjela zbog inherentnih softverskih pogrešaka^{(inherent software errors)} .
• Češće nego ne, srušio se^(crashed) nakon početnog ponovnog pokretanja instalacijskih datoteka.
• Corel Linux upravitelj datotekama nije omogućio lak pristup svojim upravljačkim programima i trebalo je puno vremena za učitavanje datoteka. To je difficult to upload/download files online , što je dodatno obeshrabrilo nove korisnike da ga odaberu.
• Bilo je poteškoća u dobivanju ^{( difficulty in getting)} tehničke podrške^{(technical support)} u pronalaženju računalnih tehničara koji su dobro upućeni u Linux , kada je to bilo potrebno.
• Budući da je većina ljudi navikla na Windows i Mac , bilo je potrebno više truda^{(required more effort)} i šira baza znanja za korištenje ovog neuspjelog operativnog sustava. Za nove korisnike bio je prilično izazovan i odvraćao ih je od bavljenja njime.
• Unatoč kasnom izdanju, Corel Linux je grafički bio daleko ispred svog vremena. Mnogi ljudi nisu mogli razumjeti ili povezati^{(could not understand or correlate)} se, što je odustajanje od toga postalo lakša opcija.

7. OS Java
^{(7. Java OS )}

Ova zamisao Sun Microsystemsa^{(brainchild of Sun Microsystems)} razvijena je uz pomoć IBM računala i puštena je u javnost 1996. godine^{(in 1996)} . Nažalost, nije krenuo kako se očekivalo, unatoč ogromnoj podršci IBM- ovih računala. Glavni razlozi odgovorni za njegov neuspjeh navedeni su u nastavku:

• Njegov učinak nije bio u rangu s konkurentima. Smatralo se da je drastično sporiji^{(drastically slower)} od softvera napisanog u other programming languages like C, C++, etc . 
• Operativni sustav Java^(Java) napisan je u Javi^(Java) , koja je bila jedan od najtežih programskih jezika^{(hardest programming languages)} u usporedbi s jednostavnijim jezicima C, C++. Ljudi uvijek preferiraju lakšu opciju, što je rezultiralo udaljavanjem korisnika od Jave^(Java) .
• Operativni sustav Java trošio je veći memorijski ^{(consumed higher memory)} prostor^(space) u usporedbi s drugim OS-om jer je dizajniran za rad na Java mrežnim strojevima i ugrađenim sustavima.
• Zbog sporih performansi i velikog zahtjeva za memorijom, potrebni hardver je bio složeniji. To je rezultiralo većim troškovima hardvera^{(higher hardware costs)} što ga čini skupljim.
• Nije pružao rezervnu mogućnost^{(no backup facility)} . Dakle, nije bilo moguće vratiti podatke izgubljene zbog kvara hardvera ili softvera.
• Slično, ne možete oporaviti prethodno pohranjene podatke u slučaju napada zlonamjernog virusa ili zlonamjernog softvera, oštećenja podataka ili slučajnog brisanja podataka.
• Java operacijskom sustavu nedostajao je dobar GUI^{(lacked a good GUI)} i stalno se zamrzavao^{(froze repeatedly)} .

8. Symbian

Operativni sustav Symbian koji je lansirala Nokia^{( launched by Nokia)} pojavio se 1997. godine^{( in the year 1997)} . Dizajniran je kao mobilni operativni i računalni sustav za pametne telefone. Osjetio je svoju prisutnost i stekao popularnost tijekom lansiranja softverske platforme Nokia S60 2002. Ali sustav je imao mnogo zabluda, što ga je svrstalo na popis deset najgorih operativnih sustava svih vremena. Pogledajmo nekoliko:

• Na ovaj neuspjeli operativni sustav lako su utjecali bugovi i virusi^{(easily affected by bugs and viruses)} .
• Bio je vrlo sklon pogreškama^{(highly prone to errors)} .
• Zadani preglednik s OS Symbian bio je vrlo loš u smislu tržišnog odziva^{(poor in terms of market response)} i nije mogao izdržati konkurenciju s Apple iOS-om 2007. i Androidom^(Android) u sljedećoj godini.
• Nikada ne bi mogao ispraviti nedostatke ili poboljšati svoje korisničko sučelje^{(User Interface)} . Preslikavao je korisničko sučelje Applea^(Apple) i Androida^(Android) , njegovih konkurenata.
• Nokia nije osjetila svoju prisutnost niti tražila nove aplikacije za svoj propali operativni sustav kako bi poboljšala svoj tržišni otisak.
• Symbian OS je teško učitao web-stranice s WAP-om^{(difficult to load WAP-enabled web pages)} . WAP ili Wireless Application Protocol je ugovor koji omogućuje trenutnu povezanost između bežičnih uređaja poput mobilnih telefona i interneta.
• Ovaj softver nije bio kompatibilan s različitim verzijama operacijskog sustava Symbian , što je rezultiralo daljnjim smanjenjem njegove popularnosti među korisnicima.

9. NJEGOVO^{(9. ITS)}

Incompatible Timesharing System ili ITS operativni sustav bio je proizvod kasnih 1960-ih^{(product of the late 1960s)} . Napisana je na DEC PDP-6 i PDP-10 asemblerskim jezicima sa svakom datotekom pohranjenom u svom naznačenom direktoriju. Ovaj neuspjeli operacijski sustav podržavao je jedno ime datoteke od šest znakova po direktoriju. Nije izdržao test vremena i stoga je bio rangiran među deset najgorih operativnih sustava svih vremena iz razloga navedenih u nastavku:

• ITS nije zahtijevao lozinku za prijavu što je dovelo do slabljenja sigurnosti sustava^{(weakened system security)} . Svatko se mogao prijaviti u vaše interaktivne sesije.
• Korisnici su najbolje iskoristili nedostatke sustava i koristili naredbe za rušenje kako bi srušili sustav, namjerno da izazovu smetnje i smetnje.
• Privatnost korištenja također je bila ugrožena jer je svatko mogao uređivati^{(anyone could edit)} ​​vaše datoteke, online dokumente, pa čak i izvorni kod.
• Koristeći naredbu pod nazivom OS ili Out Spy^{(OS or Out Spy)} , svatko je mogao vidjeti koje se aktivnosti odvijaju na drugim korisničkim terminalima na istoj mreži.
• Korisnik može poslati trenutnu poruku bilo kome^{(instant message to anyone)} , bez obzira na to poznaju li ga ili ne.
• Jednostavan pristup, sa ili bez računa gosta, bio je dopušten. Tako je svatko mogao ući kao turist i aktivno se pridružiti sesiji. To je ne samo dalo povoda nego i potaknulo hakersku kulturu^{(encouraged the Hacker culture)} .
• Uspon i popularnost UNIX^{(rise and popularity of UNIX)} -a, višekorisničkog, višezadaćnog i stabilnijeg operativnog sustava, s vremenom je stekao popularnost u odnosu na ovaj sustav. Postao je bolja i sigurnija veza između računala i njegovih korisnika, što ih je natjeralo da se odmaknu od ITS -a . 

10. Lindows

Lindows Inc. je 2001.^{(year 2001)} godine pokušao spojiti i stvoriti mješavinu ili hibridnu verziju Linuxa i Windowsa^{(hybrid version of Linux and Windows)} , nazvavši je Lindows . U svojoj namjeri da zarobe Microsoftovo^(Microsoft) tržište i odvuku njegove kupce, njegovi su programeri došli na ovu briljantnu ideju da kombiniraju UX Windowsa^(Windows) i mogućnosti otvorenog koda Debian Linuxa^(Linux) . Nisu uspjeli u svom pokušaju iz razloga koji su detaljno navedeni u nastavku:

• Taj je sustav bio nepotrebno kompliciran^{(unnecessarily complicated)} i težak za korištenje prosječnom korisniku računala.
• Na njega su lako utjecali bugovi i virusi.
• Većina aplikacija nije radila^{(apps did not work)} na ovoj platformi.
• Aplikacije su zahtijevale korištenje softvera WINE i bile su smiješno spore^{(ridiculously slow)} u radu.
• Iako se tvrdilo da je Red Hat Linux 8 ( RH 8 ) besplatan softver, imao je visoke skrivene troškove podrške^{(high hidden support costs)} , čak i za neku osnovnu podršku.
• Lindows je izgledao vrlo nespretno i^{(clumsy-looking)} nije imao mnogo o čemu pričati ili pisati.
• Ako stvarno želite pokrenuti Windows aplikacije na Linuxu^(Linux) , bolje je nabaviti CodeWeavers 'CrossOver' Linux  aplikaciju kao alternativu.

Štoviše, zbog kršenja autorskih prava sa svojim imenom, Lindows je morao kroz razne tužbe. Microsoft je morao platiti veliku odštetu, a zatim ga je odlučio koristiti pod novim imenom Linspire .

Osobno, osim navedenih, tu su bili i neki drugi propali operativni sustavi poput GNU Herd i SCO Open Desktop koji ne zaostaju puno na listi najgorih operativnih sustava ^{(worst operating systems)} svih vremena^{(of all time)} . Ovaj popis nije konačan, ali bi za sada trebao biti dovoljan. Javite nam o čemu sljedeće želite naučiti.

Top 10 Worst Operating Systems

It is important to understand this before we dеlve any furthеr. Just like we visit a ѕalon to modify our look and bеcome trendy. Similarly, you need to fashion the hardware capabilities of уour personal computers. You must be aware of the best Operating Systems available for use today. But, you should also dwеll on the worst operating ѕystems to save yourself from slow or damaged computers. We bring to you the list of the best failed operating systems in this article.

Top 10 Worst Operating Systems

Generally abbreviated as OS, Operating System handles system data and acts as an interface between the hardware and the software of a computer. Simply put, it acts as a medium of communication for the person operating the PC and the machine itself. Operating Systems can be classified into:

• General-purpose computer operating systems
• Real-time mobile operating systems.

Let us now discuss the 10 worst Operating Systems of all time individually. 

1. MS-DOS 4.0

A proprietary product of Microsoft developed in 1986, was released in the market in 1988. Compared to the earlier versions, it was tagged to be the rotten egg of the Microsoft basket for the reasons listed below:

• It would just stop operating in the middle, out of nowhere.
• It could not multi-task; so, it would run only one program at a time 
• Due to its inability to multitask, it was unsuitable for work-station applications
• This OS was highly user-dependent. Hence, it could not be used in case the user forgot its commands. 
• For new users, it was difficult to remember all of the commands. This made them move away from this software. 
• It faced difficulty in accessing any RAM with more than 640 MB of storage space.
• It did not accept the automatic Interrupt Request (IRQ) command. Thus, a user could not run any new program while putting the program already running on hold.

2. Windows ME

Windows ME or the Millennium Edition of Windows was a proprietary software of Microsoft launched in September 2000. It had the following drawbacks:

• Being ridden with bugs, it became a highly unstable system. 
• Features like System Restore & Program Installation were a complete disaster because they re-installed the already deleted viruses on the computer.
• This made it a very slow, insecure, and unstable system.
• System parameters of some devices did not support the pre-installed hardware.
• Many a time, moving the mouse after returning to work post small breaks, resulting in Windows ME crashing.
• Another reason was that its usage was limited to home-users only.
• This OS was not available in the open market. 
• Lack of security updates was another major problem with this software.
• Trying to function as both, 16-bit & 32-bit OS brought about more chaos in its operation rather than improving it.
• The major reason for its failure was the withdrawal of support by Microsoft itself. 
• The launch of Windows XP, just within one year of the release of this software, proved to be a fatal blow.

3. Windows Vista

Windows Vista was released in the month of November in 2006, after the release of Windows XP, its powerful predecessor. It obviously had to toil hard to make a name for itself in the marketplace. Unfortunately, it could not build on its reputation and was flagged to be amongst the ten worst operating systems of all time. Here’s why:

• This software was prone to bloating i.e slowing down of programs. 
• It also occupied larger memory space due to numerous pre-installed programs and the addition of unwanted new features to the existing programs. This is known as software creep.
• Such software creeping made it confusing and at times, difficult to use this failed operating system.  
• There was poor compatibility between the hardware and the software. For example, Windows 7 is not compatible with Windows Vista. So, usually, both cannot be used simultaneously, on the same PC, due to different hardware requirements. Therefore, Windows Vista required only Vista-compatible computers.
• For security reasons, it only allowed the installation of signed drivers. This meant that a software developer would need to obtain an Authenticode certificate from Microsoft. This certification was very costly and out of reach for smaller, non-branded developers.
• Pricing was another issue with this software as it was very costly for most people.
• This OS did not allow certain programs such as Android Package Kit for installation of mobile apps, mobile games, Aero engineering, Windows movie maker versions, etc.
• Poor marketing of this operating system became another cause of its poor ranking.

4. Windows 8/8.1

With the idea of bringing out sweeping changes to the user interface, this software was launched in the year 2012. Microsoft realized that people no longer worked on a single device viz the personal computer; instead, they were using various devices like laptops, tablets, phones, etc. Therefore, Windows 8 was introduced to cater to the requirements of multiple devices. It failed to achieve its objective because:

• The discontinuation of the start button was an utterly confusing feature of this version.
• It did not fit the needs of a home computer as users kept getting more confused and frustrated than at ease.
• It disabled booting i.e. the process of starting a computer or a desktop. Instead, it enabled the booting of the start screen, leaving the users bewildered, yet again.
• Eventually, Microsoft had to restore the Start button on the desktop to avoid all of the uncalled-for commotions.
• Most of the applications in this OS were unable to work cross-platform and were functional in Windows 8 only.
• One had to search for the search icon, to initiate any search on your computer.
• This feature could have been easily placed on the desktop and this predicament could have been avoided, altogether.
• Windows 8 required training of company employees to use this software in an organization. This resulted not only in unwanted training costs but also, in the loss of employee productivity. It took more time, effort, and money to familiarize non-technical users with this software, generating more harm than good for the said organization. 
• Upgradation to this system involved a change of drivers in the peripheral devices attached to the computer. Hence, all devices like printers, microphones, speakers, cameras, etc. required new drivers, thereby increasing system costs, even more.
• To invite a remote speaker using Windows 8 laptop, the remote microphone required a change to a compatible driver. This often made the use of remote meetings unfeasible.
• A split-brain syndrome kind of situation was created in an office employing Windows 8 systems. It could lead to data getting corrupt or inconsistent.
• Windows 8 resulted in a lack of efficient exchange of information amongst different employees in an organization and various users the world over.

In view of the above drawbacks, Microsoft released Windows 8.1 in October 2013, one year after the release of Windows 8. Window 8.1 fixed the existing flaws by overcoming the inconsistencies in Windows 8 and enabled the users to get a more efficient functioning. Although, that too was quickly given up in favor of Windows 10.

5. Window 1.01

It is a Microsoft closed source, graphical user interface rather than DOS command-line interface commercial software. Though it was announced to be made public in November 1983, it was finally released as an added version of MS-DOS in November 1985. It was included in the list of 10 worst operating systems of all time due to the following reasons:

• Its poorly designed user interface could not meet the specific needs of the consumers.
• Its sudden collapse in the midst of a running program showed its poor workability. This just added fuel to the fire.
• The delay in the introduction of this system by two years further caused its downfall.
• The availability of the far superior Mac 2.1 OS which included AppleTalk networking, PostScript printing with laser writer printer, and sophisticated PC-based Hierarchical File System overpowered its features. Consequently, Microsoft could not generate much user interest in Windows 8 at the time of its launch. 
• Its emphasis on the use of mouse input to control the user interface was not widespread at the time. It was beyond user comprehension and thus, couldn’t garner a fanbase.
• Its non-Y2K compliance coupled with lower hardware specifications resulted in performance issues.
• Its limited resource availability was unable to generate the desired interest and/or impress the new Windows users.

6. Corel Linux

Of the three major OS for computers namely Windows, Mac, and Linux, Linux is the least talked about the open-source failed operating system. Linux was created by Debian and was released in the open market in November of 1999. It was touted to finally stop the monopoly of Microsoft but it failed miserably because:

• Its late release and existing availability of other operating systems like Microsoft Windows 98, Windows 2000, and Apple Mac OS 9, didn’t help it gain popularity.
• Unlike Windows and Mac, which had many definite versions, Corel Linux had no standard edition. With hundreds of user-developed editions floating in the market, it became very challenging to choose the best one. This confusion dissuaded new users from accepting it.
• The installation process of this OS was very cumbersome making the installation of new program files by new users a marathon.
• Most times, the installation of this software failed due to inherent software errors.
• More often than not, it crashed after an initial reboot of the installation files.
• Corel Linux file manager did not provide easy access to its drivers and took a long time to load files. This made it difficult to upload/download files online, further, discouraging new users from choosing it.
• There was difficulty in getting technical support in finding computer technicians well versed in Linux, as and when needed.
• With most of the people used to Windows and Mac, it required more effort and a broader knowledge base to use this failed operating system. It was quite challenging for new users and deterred them from pursuing it.
• Despite its late release, Corel Linux was graphically way ahead of its times. Many people could not understand or correlate, making a withdrawal from it an easier option.

7. Java OS

This brainchild of Sun Microsystems was developed with the assistance of IBM computers and was released to the public in 1996. Unfortunately, it did not take off as anticipated, in spite of the tremendous support from IBM computers. The main reasons responsible for its failure are listed below:

• Its performance was not at par with its competitors. It was considered to be drastically slower than the software written in other programming languages like C, C++, etc. 
• Java operating system was written in Java, which was one of the hardest programming languages in comparison to the simpler C, C++ languages. People always prefer the easier option, which resulted in users distancing themselves from Java.
• Java operating system consumed higher memory space as compared to other OS because it was designed to run on Java network machines and embedded systems.
• Due to its slow performance and high memory requirement, the hardware required was more complex. This resulted in higher hardware costs making it costlier.
• It provided no backup facility. So, it was not possible to recover data lost due to hardware or software failure.
• Similarly, you could not recover any previously stored data in the event of a malicious virus or malware attack, data corruption, or accidental data deletion.
• Java operating system lacked a good GUI and froze repeatedly.

8. Symbian

The Symbian operating system launched by Nokia came into existence in the year 1997. It was designed as a mobile operating and computing system for smartphones. It made its presence felt and gained popularity during the launch of the Nokia S60 software platform in 2002. But the system had many fallacies, placing it in the list of the ten worst operating systems of all time. Let us take a look at a few:

• This failed operating system was easily affected by bugs and viruses.
• It was highly prone to errors.
• The default browser provided with Symbian OS was very poor in terms of market response and could not stand in competition with Apple iOS in 2007 and Android in the following year.
• It could never rectify the deficiencies or improve its User Interface. It mirrored the user interface of Apple and Android, its competitors.
• Nokia did not make its presence felt or search for new applications for its failed operating system to improve its market footprint.
• The Symbian OS found it difficult to load WAP-enabled web pages. WAP or Wireless Application Protocol is a contract that enables instant connectivity between wireless devices like mobile phones and the internet.
• This software was incompatible with various versions of the Symbian operating system, resulting in further decreases in its popularity among its users.

9. ITS

The Incompatible Timesharing System or ITS operating system was a product of the late 1960s. It was written in DEC PDP-6 and PDP-10 assembly languages with each file stored in its designated directory. This failed operating system supported one mono-case, six-character file name per directory. It could not stand the test of time and was thus, ranked amongst the ten worst operating systems of all time for the reasons indicated below:

• ITS did not require a password to log in which led to weakened system security. Anyone could log into your interactive sessions.
• Users made the best of system flaws and used crash commands to crash the system, on purpose to cause nuisance and disturbance.
• Privacy of use also stood compromised because anyone could edit your files, online documents, and even the source code.
• Using a command called OS or Out Spy, anyone could see what activities were taking place in other user terminals on the same network.
• A user could send an instant message to anyone, irrespective of whether they knew them or not.
• Ease of access, with or without a guest account, was allowed. Thus, anyone could enter like a tourist and actively join a session. This not only gave rise to but also encouraged the Hacker culture.
• The rise and popularity of UNIX, a multi-user, multi-tasking, and more stable operating system gained popularity over this system, with time. It became a better and safer link between the computer and its users, making them pull away from ITS. 

10. Lindows

Lindows Inc. in the year 2001, tried to amalgamate and create a mix or hybrid version of Linux and Windows, naming it Lindows. In their bid to capture the Microsoft market and pull its customers away, its developers came up with this brilliant idea to combine the UX of Windows and the open-source capabilities of Debian Linux. They failed in their attempt miserably for reasons detailed below:

• This system was unnecessarily complicated and difficult to use by the average computer user.
• It was easily affected by bugs and viruses.
• The majority of the apps did not work on this platform.
• The applications required the use of WINE software and were ridiculously slow in operating.
• Though Red Hat Linux 8 (RH 8) was claimed to be free software, it had high hidden support costs, even for some basic support.
• Lindows was very clumsy-looking with not much to talk or write about.
• If you really want to run Windows applications on Linux, it is better to get CodeWeavers ‘CrossOver’ Linux application as an alternative.

Moreover, due to copyright infringement with its name, Lindows had to through various lawsuits. Microsoft had to pay a heavy compensation and then, decided to use it under a new name Linspire.
