Windows 10: Service registration is missing or corrupt

Before I updated to Windows 10, I must have damaged some files whilst trying to turn off Windows 10 notifications in Windows 7. I couldn't do any updates in Windows 7 either.

There is no error code. Windows update troubleshooter says: "Service registration is missing or corrupt."

I ran sfc/ scannow, it said it found corrupt files but was unable to fix it. The CBS log is attached. CBS.rar

:)

 

"Service registration is missing or corrupt"

Okay, try resetting update components.

Open administrative Command Prompt and type following commands one-by-one followed by Enter key.

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

Ren C:\Windows\System32\catroot2 Catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

Close Command Prompt and see if Windows Updates works then.

Hope this helps, Good luck!

Hi mAReDux and welcome to Tenforums.

Please open an administrative command prompt and type the following
Code: findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"[/quote] This will place a much smaller text file on your desktop of only the important data to be evaluated from your CBS log.
Thanks.

EDIT: You can also try manually resetting the windows update components (skipping step #4):

I don't know if the auto-Fix It will run in W10; I've never tried it. Probably the W8 version will.

 

You can first try this tutorial:
Windows Update - Reset in Windows 10 - Windows 10 Forums


You can also try fixing things, by copy & pasting the following in an Admin Command Prompt:

fsutil resource setautoreset true c:\&fsutil usn deletejournal /d /n c:&Dism.exe /online /Cleanup-Image /StartComponentCleanup&&sfc /scannow&Dism.exe /Online /Cleanup-Image /RestoreHealth&sfc /scannow&Dism.exe /Online /Cleanup-Image /StartComponentCleanup /ResetBase&pause


And let it run through.
Then reboot and run it again, to check if it cleaned and fixed everything.
It may take awhile depending on your hardware(HDD or SSD),
and it may appear to freeze at 20% on the third part,
just be patient and let in run out.



If this doesn't help after a couple run-throughs and reboots, you could try a repair install.

 

That fixit is the troubleshooter which can be also found on W10-Control Panel>troubleshooting>view all *Smile
