SVCHOST.EXE jedan je od onih tajanstvenih procesa koji se neprestano izvršavaju u sustavu Windows^(Windows) i koji je krajnje bitan, ali nikad ne znate što točno radi. Dakle, što je SVCHOST.EXE ? Identificiranje stvarnih usluga i programa koji se izvode unutar svakog procesa SVCHOST.EXE zadatak je vrijedan poznavanja, posebno kada proces pojede 99 ili 100 posto vašeg CPU-a!

Stoga prije nego zaronimo u rješenja, idemo dublje razumjeti što ovaj proces zapravo čini i kako možete riješiti neke probleme koji bi se mogli pojaviti. Prvo, svchost je skraćenica za “ Host usluge^{(Service Host)} ” i radi upravo ono što ime sugerira: pomaže u “hostovanju” usluga. Usluga u sustavu Windows^(Windows) jednostavno je program u operativnom sustavu koji radi određeni posao i radi u pozadini u svakom trenutku kada je vaše računalo uključeno, čak i ako niste prijavljeni.

Većina programa s kojima ste upoznati radi se kao samostalna izvršna datoteka, kao što je .EXE. Međutim, većina usluga implementirana je u obliku DLL^(DLLs) -ova , koji se ne mogu pokrenuti sami. Stoga^(Hence) svchost učitava te DLL^(DLLs) -ove i sam ih pokreće. Zato ćete, kada otvorite Windows Task Manager , vidjeti gomilu pokreta svchost.exe. Ako želite više informacija o upravitelju zadataka^{(Task Manger)} , pogledajte moje članke o razumijevanju upravitelja zadataka .

Primijetit ćete da se na mom računalu trenutno izvodi osam svchost procesa, svi koriste različite količine memorije i rade pod različitim korisničkim imenima. Recimo da jedan od njih radi s pretjerano visokom upotrebom CPU -a od 100 posto, kako možemo identificirati stvarnu aplikaciju koja radi?

Zapravo postoje dva načina za to: sve to učiniti ručno pomoću naredbenog retka i alata za usluge^(Services) ili korištenjem aplikacije treće strane. Ovdje ću spomenuti oboje u slučaju da vam jedan ne odgovara.

Prvo provjerite ima li virusa

Prije nego što uđemo u detalje u nastavku, vrijedi napomenuti da postoje slučajevi u kojima je svchost.exe zapravo virus. Budući da se radi o sustavnom procesu, zlonamjerni koderi vole koristiti ime svchost kako bi ostali skriveni. Ako se datoteka nalazi u Windows/system32 , više nego vjerojatno nije virus, no uvijek preporučujem da izvršite skeniranje samo da budete sigurni.

Ako još nemate antivirusni program, preporučam korištenje Kasperskyja^(Kaspersky) ili Bitdefendera^{(Bitdefender)} budući da su oni stalno na vrhu ljestvice AV-Test i AV-Comparatives . Nisu besplatni, ali većina besplatnih antivirusnih programa na kraju spaja dodatni neželjeni softver ili preusmjerava vaš preglednik na svoje "sigurno" rješenje za pretraživanje, koje uopće nije sigurno i samo vas prati i prikazuje vam više oglasa.

Identificirajte^(Identify) svchost.exe procese^(Processes) putem naredbenog retka^{(Command Prompt)} (težak način)

1. Prvo, samo naprijed i kliknite na Start , a zatim Run i upišite CMD i kliknite OK. U sustavu Windows 8.1^{(Windows 8.1)} , samo naprijed i desnom tipkom miša kliknite gumb Start i odaberite Pokreni^(Run) .

2. U naredbeni prozor upišite sljedeće i pritisnite Enter

tasklist /svc /fi “imagename eq svchost.exe

Trebali biste dobiti izlaz kao što je prikazano u nastavku s imenom, PID -om i opisom usluge

Sada ćete vidjeti svaki svchost proces zajedno s njegovim jedinstvenim ID brojem i uslugama za koje je odgovoran. Međutim, ta su imena još uvijek vrlo zagonetna i sve su skraćena imena. Kako bismo dobili još korisnih informacija o procesu, možemo koristiti preglednik Services u sustavu Windows.^(Services)

3. Desnom tipkom miša kliknite Moje računalo^{(My Computer)} , odaberite Upravljanje^(Manage) . Na rezultirajućem zaslonu odaberite Upravljanje računalom,^{(Computer Management)} a zatim odaberite Usluge i aplikacije^{( Services and Applications)} . Na kraju odaberite Usluge^(Services) .

4. Sada pokušajte uskladiti zagonetni naziv usluge Windows s lako čitljivim nazivima na kartici Usluge^(Services) . Ovo je malo i može potrajati jer ako uzmete proces s ID-om 1436^{(ID 1436)} i zove se WudfSvc , morate ga pokušati pronaći na popisu. Ako dvaput kliknete na jedan od naziva usluga, vidjet ćete i njihov zagonetni naziv, tako da ih možete spojiti. U mom slučaju, pretpostavio sam da W znači da proces počinje s " Windows " i otvarao sam ih dok nisam vidio podudaranje.

Kao što možete vidjeti, usluga Windows Driver Foundation zapravo se skraćeno zove wudfsvc !

Identificirajte^(Identify) svchost.exe procese^(Processes) putem Process Explorera^{(Process Explorer)}  (jednostavan način)

Ako vam se čini da je pretežak, postoji mnogo lakši način! Pogledajte Microsoftov^(Microsoft) alat Process Explorer (izvorno iz SysInternals ). Alat je potpuno besplatan i daje vam detaljne informacije za svaki proces koji se trenutno izvodi.

Nakon što je preuzmete, samo pokrenite exe datoteku jer ne mora biti instalirana. Zadržite pokazivač miša iznad procesa svchost i dobit ćete skočni prozor koji vam pokazuje koje usluge se pokreću pod tim procesom. Lijepa stvar kod istraživača procesa je što vam daje prijateljski naziv za svaki proces umjesto kratkog naziva.

Windows 8 Upravitelj zadataka

Posljednja stvar koju sam želio spomenuti je činjenica da Windows 8 upravitelj zadataka u osnovi čini korištenje naredbenog retka ili Process Explorera^(Explorer) potpuno zastarjelim. Otvorite Upravitelj zadataka^{(Task Manager)} pritiskom na CTRL + SHIFT + ESC i pomaknite se prema dolje na kartici Procesi^(Processes) do mjesta gdje piše Windows Procesi^{(Windows Processes)} .

Ovdje ćete vidjeti svaki proces svchost.exe naveden kao Service Host: nakon čega slijedi vrsta računa pod kojim se izvodi (Lokalni sustav^(System) , Mrežna usluga^{(Network Service)} , itd.). Također će imati broj pored sebe i ako proširite stavku klikom na strelicu, također ćete vidjeti svaku uslugu koja se izvodi pod tim određenim procesom.

Popravak SVCHOST visoke upotrebe CPU-a

Sada kada ste točno shvatili koji proces jede cijeli vaš CPU , možemo se pozabaviti kako to popraviti. Ako ste otkrili da proces nije proces u sustavu Windows^(Windows) , kao što je Windows Update ili Windows Firewall , itd., jednostavno ukinite proces i deinstalirajte program.

Međutim, većinu vremena kada se ovaj problem javlja, on ima neke veze s procesom u sustavu Windows^(Windows) . Najbolje rješenje u ovom slučaju je instaliranje svih najnovijih ažuriranja s Microsoftove web stranice. Ako to ne možete učiniti normalno u sustavu Windows^(Windows) , pokušajte ponovno pokrenuti računalo u sigurnom načinu rada i pokušajte ponovo.

Također, ako možete doći do kartice Usluge^(Services) kao što smo to učinili gore, samo naprijed i desnom tipkom miša kliknite uslugu i odaberite Onemogući^(Disable) . Čak i ako je to Windows Update ili vatrozid^(Firewall) , ne brinite, možete ga ponovno omogućiti kasnije. Zatim ponovno pokrenite računalo i idite na Microsoftovu web stranicu i ručno preuzmite ažuriranja. Ponovno omogućite uslugu i ponovno pokrenite računalo i nadamo se da stvari rade!

Da biste onemogućili uslugu u sustavu Windows^(Windows) , kliknite je desnom tipkom miša na kartici Usluge^(Services) i odaberite Svojstva^(Properties) .

Zatim odaberite Onemogućeno^(Disabled) iz kombiniranog okvira Vrsta pokretanja^{(Startup type)} koji se nalazi u sredini dijaloškog okvira:

Prošao sam kroz ovaj proces nekoliko puta i uspio mi je. Dakle, opet, prvo onemogućite uslugu, zatim ponovno pokrenite računalo, zatim ručno instalirajte ažuriranja, zatim ponovno omogućite uslugu, a zatim ponovno pokrenite računalo. Ako to ne uspije, morate izvesti popravnu instalaciju sustava Windows . Potražite na Googleu^(Google) instalaciju za popravak i slijedite korake. Ako koristite Windows 8 , možete osvježiti svoje računalo^{(refresh your computer)} . Ako imate pitanja, ostavite komentar. Uživati!

How to Fix Svchost.exe High CPU Usage

SVCHOST.EXE is one of those mysterious processes that constantly runs in Windows and is utterly essential, yet you never know exactly what it is doing. So what is SVCHOST.EXE? Identifying the actual services and programs that are running inside each SVCHOST.EXE process is a task well worth knowing, especially when the process eats up 99 or 100 percent of your CPU!

So before we dive into solutions, let’s get a deeper understanding of what this process actually does and how you can go about fixing some of the problems that might occur. Firstly, svchost stands for “Service Host” and it does exactly what as the name suggest: helps to “host” services. A service in Windows is simply a program in the operating system that does a particular job and runs in the background at all times when your computer is on, even if you are not logged in.

Most programs that you are familiar with run as a stand-alone executable, such .EXE. However, most services are implemented in the form of DLLs, which cannot run on their own. Hence, svchost loads those DLLs and runs them itself. That’s why when you open the Windows Task Manager, you’ll see a bunch of svchost.exe processes running. If you want more info on the Task Manger, check out my articles on understanding the Task Manager.

You’ll notice that there are currently eight svchost processes running on my computer, all using up various amounts of memory and running under different user names. So let’s say one of them is running at an excessively high CPU usage of 100 percent, how can we identify the actual application running?

There are actually two ways to go about this: doing it all manually using the command prompt and Services tool or by using a third party application. I’m going to mention both here in case one does not work for you.

Check for Viruses First

Before we get into the details below, it’s worth noting that there are cases where svchost.exe is actually a virus. Since it’s a system process, malicious coders like to use the name svchost to remain hidden. If the file is located in Windows/system32, it’s more than likely not a virus, however I always recommend performing a scan just to be sure.

If you don’t already have an anti-virus program, I recommend using either Kaspersky or Bitdefender since they consistently perform at the top in AV-Test and AV-Comparatives rankings. They are not free, but most free antivirus programs end up bundling extra junk software or redirecting your browser to their “secure” search solution, which isn’t secure at all and just tracks you and shows you more ads.

Identify svchost.exe Processes via Command Prompt (hard way)

1. First, go ahead and click on Start and then Run and type in CMD and click OK. In Windows 8.1, go ahead and right-click on the Start button and choose Run.

2. Type in the following into the command window and press Enter

tasklist /svc /fi “imagename eq svchost.exe

You should get an output as shown below with the name, PID, and service description

You’ll now see each svchost process along with it’s unique ID number and the services it is responsible for running. However, these names are still very cryptic and are all short-hand names. In order to get some more useful information about the process, we can use the Services browser in Windows.

3. Right-click on My Computer, choose Manage. On the resulting screen, choose Computer Management and then choose Services and Applications. Finally, choose Services.

4. Now try to match the cryptic Windows service name with the easily readable names in the Services tab. This is a little and can take some time because if you take the process with ID 1436 and it’s name WudfSvc, you have to try to find it in the list. If you double-click on one the service names, you’ll see their cryptic name also, so that’s how you can match them up. In my case, I guessed that the W means the process starts with “Windows” and opened them until I saw a match.

As you can see, the Windows Driver Foundation service is actually called wudfsvc for short!

Identify svchost.exe Processes via Process Explorer (easy way)

If you found to be too difficult, there is a much easier way! Check out the Process Explorer tool from Microsoft (originally from SysInternals). The tool is completely free and gives you detailed information for each process currently running.

Once you download it, just run the exe file as it does not have to be installed. Hover your mouse over the svchost process and you’ll get a popup showing you which services are running under that process. The nice thing about process explorer is that it gets you the friendly name for each process instead of the short name.

Windows 8 Task Manager

One last thing I wanted to mention was the fact that the Windows 8 task manager basically makes using the command line or Process Explorer totally obsolete. Open the Task Manager by pressing CTRL + SHIFT + ESC and scroll down on the Processes tab to where it says Windows Processes.

Here you will see every svchost.exe process listed as Service Host: followed by the type of account it is running under (Local System, Network Service, etc). It’ll also have a number next to it and if you expand the item out by clicking the arrow, you will also see every service running under that particular process.

Fixing SVCHOST High CPU Usage

Now that you have figured out exactly which process is eating up all of your CPU, we can address how to fix it. If you have found that the process is not a Windows process, such as Windows Update or Windows Firewall, etc, then simply kill the process and uninstall the program.

However, most of the time that this problem occurs, it has something to do with a Windows process. The best solution in this case is to install all of the latest updates from Microsoft’s web site. If you’re not able to do so normally in Windows, try restarting the computer in safe mode and try it again.

Also, if you can get to the Services tab like we did above, go ahead and right-click on the service and choose Disable. Even if it’s Windows Update or the Firewall, don’t worry, you can re-enable it later. Then restart the computer and go to Microsoft’s web site and manually get the updates. Re-enable the service and restart the computer again and hopefully things are working!

In order to disable a service in Windows, right-click on it from the Services tab and choose Properties.

Next choose Disabled from the Startup type combo box located in the middle of the dialog box:

I have gone through this process a couple of times and it has worked for me. So again, first disable the service, then restart computer, then install updates manually, then re-enable service, and then restart computer again. If this doesn’t work, you have to perform a repair install of Windows. Do a Google search for repair install and follow the steps. If you’re running Windows 8, you can refresh your computer. If you have any questions, post a comment. Enjoy!
