Ako dobivate pogrešku tijekom nadogradnje Windows 11/10 koja kaže  STOP 0XC000021A ili STATUS_SYSTEM_PROCESS_TERMINATED, ^{(STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED, )} onda je to sigurnosni problem unutar sustava Windows . Također je moguće da sistemske datoteke imaju problem i da su pogrešno izmijenjene. To ne znači nužno da postoji problem sa zlonamjernim softverom, ali jedna od nedavno instaliranih aplikacija možda je izmijenila ili oštetila neke osnovne datoteke. Ovaj vodič će vam pomoći da riješite ovaj problem.

0XC000021a, STATUS PROCES SUSTAVA ZAVRŠEN^{(STATUS SYSTEM PROCESS TERMINATED)}

Dobit ćete pogrešku c000021a^(c000021a) (fatalna pogreška sustava^{(System Error)} ) kada Windows otkrije sigurnosni kompromis u podsustavu korisničkog načina rada, kao što je WinLogon ili CSRSS (podsustav vremena izvršavanja klijentskog poslužitelja^{(Server Run-Time Subsystem)} ). Kada se takav proces sustava prekine, tada se vaš sustav prebacuje u način rada jezgre. jer ne može raditi bez CSRSS ili WinLogon .

Drugi uzrok pogreške c000021a su neusklađene datoteke na tvrdom disku. Ovu pogrešku dobivate nakon vraćanja sistemskih datoteka iz sigurnosne kopije ili instaliranja ili ažuriranja upravljačkih programa uređaja^{(updating device drivers)} , servisa ili softvera treće strane. U tom slučaju program za vraćanje preskače ključne sistemske datoteke, uglavnom zato što je program utvrdio da ih sustav koristi.

This error occurs when a user-mode subsystem, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), has been fatally compromised and security can no longer be guaranteed. In response, the operating system switches to kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, this is one of the few cases where the failure of a user-mode service can shut down the system.

c000021A Fatalna pogreška sustava^{(Fatal System Error)} u Windows 11/10

Fatalnu grešku sustava^{(Fatal System Error)} možete dobiti iz različitih čimbenika. U ovom odjeljku ćemo se pozabaviti metodama rješavanja problema za sve njih. Neki popravci rade samo kada možete pristupiti Windows okruženju, a neki rade na BSoD-ovima^(BSoDs) . Ovdje su poželjna rješenja:

1. Deinstalirajte štetni softver.
2. Pokrenite Provjeru sistemskih datoteka
3. Popravite to naredbom DISM
4. Ponovo izgradi BCD i popravi MBR
5. Popravite greške na tvrdom disku
6. Izvršite vraćanje sustava.
7. Koristite opciju Cloud Reset.
8. Obratite se Microsoftu.

Ako ne možete normalno pokrenuti radnu površinu, možda ćete morati pristupiti naprednim opcijama pokretanja^{(access Advanced Startup Options)} da biste pristupili alatima za oporavak.

1] Deinstalirajte štetni softver

Sjećate li se kada ste prvi put počeli doživljavati pogrešku 0xc000021a? To može biti odmah nakon što ste instalirali ili ažurirali aplikaciju, uslugu sustava ili upravljački program.

Posljednji softver koji ste instalirali ili ažurirali mogao bi biti krivac. Ako je to vaš slučaj, problem možete riješiti deinstaliranjem ili onemogućavanjem softvera koji greši. Pritisnite tipku  Windows i R^{(Windows key and R)} istovremeno da otvorite dijaloški okvir Pokreni .^(Run)

Upišite appwiz.cpl u dijaloški okvir Pokreni^(Run) i kliknite U redu. Možete kliknuti stupac Instalirano na^{(Installed On)} da biste sortirali aplikacije prema datumu instaliranja s popisa aplikacija. To vam pomaže pronaći najnoviju instalaciju koja je možda uzrokovala pogrešku.

Desnom tipkom miša kliknite^{(Right-click)} aplikaciju i odaberite  Deinstaliraj^(Uninstall) . Slijedite upute na zaslonu da biste dovršili deinstalaciju.

Ako ste nedavno instalirali ili ažurirali bilo koji softver upravljačkog^(Driver) programa, razmislite o njegovom uklanjanju.

Međutim, ako je šteta već učinjena, deinstalacija neće pomoći. U tom slučaju trebate izvršiti vraćanje sustava kako biste se vratili u stabilno stanje računala.

2] Pokrenite provjeru sistemskih datoteka

Pokrenite System File Checker u sigurnom načinu rada i pogledajte hoće li to pomoći. To će popraviti oštećene ili oštećene Windows datoteke. Morat ćete pokrenuti ovu naredbu iz povišenog CMD -a , tj. naredbenog retka pokrenutog s administratorskim privilegijama.

3] Pokrenite DISM

Ako ste dobili pristup sustavu iz prethodnog rješenja, ali niste mogli popraviti pogrešku c000021a, možete pokrenuti DISM naredbu u naredbenom^{(Command Prompt)} retku .

Prvo pokrenite svoje računalo u Windows Safe Mode s naredbenim redkom^{(Windows Safe Mode with Command Prompt)} . U prozoru naredbenog retka^{(Command Prompt)} unesite sljedeću naredbu i pokrenite je pritiskom na ENTER:

dism /image:C:\/cleanup-image/revertpendingactions

4] Ponovno izgradi BCD i popravi MBR

Podaci o konfiguraciji pokretanja ( BCD ) je baza podataka neovisna o firmveru za konfiguracijske podatke tijekom pokretanja. Da biste  obnovili BCD^{(rebuild the BCD)} ili datoteku s podacima o konfiguraciji pokretanja^{(Boot Configuration Data)} u sustavu Windows^(Windows) , upišite sljedeću naredbu i pritisnite Enter . Morat ćete koristiti naredbeni redak s povišenim admin.

bootrec /rebuildbcd

Da biste dobili novi bootloader, upišite sljedeću naredbu u povišeni naredbeni redak.

bcdboot c:\windows /s c:

C je pogon vašeg sustava na kojem je instaliran Windows . Ako to ne uspije, možete pokušati popraviti glavni zapis za pokretanje^{(repairing the Master Boot Record)} .

5] Popravite greške na tvrdom disku

Ovo možda nije 100% potpuno dokazano rješenje, ali možete pokrenuti chkdsk u naredbenom retku^{(run chkdsk in the command prompt )} da vidite da nemate problema s tvrdim diskom. Možete izvršiti sljedeću naredbu:

chkdsk c: /f /r

Moguće je da prilikom instaliranja programa na oštećeni dio diska može doći do problema.

Povezano^(Related) :  Pogreška 0xc000021a ili 0xc0000001 , Vaše računalo se nije moglo ispravno pokrenuti.

6] Pokrenite Vraćanje sustava

Možete posegnuti za vraćanjem sustava . i vidi hoće li to pomoći.

Ako dobijete Stop Error 0xc000021a , a vraćanje sustava^{(System Restore)} prestane raditi nakon ažuriranja ^(Update)sustava Windows 10^{(Windows 10)} , onda je to poznat problem za Windows 10 . Ovaj vam post može pomoći – Vraćanje sustava ne radi nakon ažuriranja sustava Windows 10 .

7] Izvršite Cloud Reset

Ako ga vraćanje sustava ne popravi, posljednja opcija je resetiranje u oblaku^{(do a Cloud Reset)} .

8] Obratite se Microsoftu

Ako se čini da ništa ne radi, uvijek možete kontaktirati  Microsoftov^{(Microsoft Support)}  tim za podršku slijedeći ovu vezu.

Fix c000021A Fatal System Error on Windows 11/10

If уou аre getting an error while Windows 11/10 upgrade which saуs  STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED, then it’s a security issue within the Windows. It is also possible that the system files have an issue, and they have been incorrectly modified. This does not necessarily mean that there is a malware problem, but one of the recently installed applications might have modified or corrupted some core files. This guide will help you troubleshoot this problem.

0XC000021a, STATUS SYSTEM PROCESS TERMINATED

You get the c000021a (Fatal System Error) error when Windows detects security compromise in a user-mode subsystem, such as WinLogon or the CSRSS (Client Server Run-Time Subsystem). When such a system process is terminated, then your system switches to kernel mode. because it can’t operate without CSRSS or WinLogon.

Another cause of the c000021a error is mismatched files in the hard drive. You get this error after restoring system files from a backup or installing or updating device drivers, service, or third-party software. In this case, the restore program skips crucial system files, mostly because the program determined that they are in use by the system.

This error occurs when a user-mode subsystem, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), has been fatally compromised and security can no longer be guaranteed. In response, the operating system switches to kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, this is one of the few cases where the failure of a user-mode service can shut down the system.

c000021A Fatal System Error on Windows 11/10

You may get the Fatal System Error from various factors. In this section, we’ll tackle the troubleshooting methods for them all. Some fixes work only when you can access the Windows environment and some work on BSoDs. Here are the solutions preferred:

1. Uninstall the offending software.
2. Run System File Checker
3. Fix it with the DISM command
4. Rebuild BCD and Fix MBR
5. Repair hard-disk errors
6. Perform System Restore.
7. Use Cloud Reset option.
8. Contact Microsoft.

If you cannot boot to your desktop normally, you may have to access Advanced Startup Options to access the recovery tools.

1] Uninstall the offending software

Do you remember when you first started experiencing the 0xc000021a error? It could be immediately after you installed or updated an application, system service, or driver.

The last software you installed or updated could be the culprit. If this is the case for you, you can fix the issue by uninstalling or disabling the buggy software. Press the Windows key and R simultaneously to open the Run dialog box.

Type appwiz.cpl in the Run dialog box and click OK. You can click on the Installed On column to sort the apps by their install date from the list of applications. This helps you find the most recent installation that might’ve caused the error.

Right-click on the application and select Uninstall. Follow the on-screen instructions to complete the uninstallation.

If you recently installed or updated any Driver software, you may want to consider removing it.

However, if the damage is already done, uninstallation will not help. In that case, you should perform a system restore to get back to a stable state of PC.

2] Run System File Checker

Run System File Checker in Safe Mode and see if that helps. This will repair corrupted or damaged Windows files. You will need to run this command from elevated CMD i.e. command prompt launched with admin privileges.

3] Run DISM

If you gained access to the system from the previous solution but couldn’t fix the c000021a error, you can run the DISM command in Command Prompt.

First, boot your computer into the Windows Safe Mode with Command Prompt. In the Command Prompt window, enter the following command and run it by pressing ENTER:

dism /image:C:\/cleanup-image/revertpendingactions

4] Rebuild BCD and Fix MBR

Boot Configuration Data (BCD) is a firmware-independent database for boot-time configuration data. To rebuild the BCD or Boot Configuration Data file in Windows type the following command and hit Enter. You will need to use the admin elevated command prompt.

bootrec /rebuildbcd

To get a new bootloader, type in the following command in the elevated command prompt.

bcdboot c:\windows /s c:

C is your system drive where Windows is installed. If this doesn’t work, you can try repairing the Master Boot Record.

5] Repair hard-disk errors

This may not be a 100% full proof solution, but you can run chkdsk in the command prompt to see you don’t have any issue with your hard drive. You could execute the following command:

chkdsk c: /f /r

It is possible that when installing programs on the corrupt part of the disk might cause issues.
