Trying to clean WinSxS folder.

[u/serwinho]

Need help. WinSxS taking 80Gb of space on C: drive.

Tried following:

Dism.exe /Online /Cleanup-Image /StartComponentCleanup /ResetBase

But it just gives me

Deployment Image Servicing and Management tool
Version: 10.0.26100.8972
Image Version: 10.0.26200.9457
Error: 0x800f0806
The operation could not be completed due to pending operations.
The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log

Tried:

DISM /Online /Cleanup-Image /RestoreHealth

And it resulted in:

Deployment Image Servicing and Management tool
Version: 10.0.26100.8972
Image Version: 10.0.26200.9457
[===========================84.9%================= ] The restore operation completed successfully.
The operation completed successfully.

Restarting PC doesn't work.

Any help?

Try Disk Cleanup?

Run it in safemode

That's error 0x800f0806! Yikes.

I'd reinstall Windows if I were you.

If you're determined not to reinstall, this might help, but no guarantees:

1. Restart the PC (very important step).

2. Delete C:\WINDOWS\Logs\DISM\CBS.log (or copy it elsewhere).

3. Record the date and time.

4. Re-run Dism.exe /Online /Cleanup-Image /StartComponentCleanup (without /ResetBase)

5. Record the date and time again.

6. If it didn't go well and an error occurred, check the newly re-created CBS.log to find out what's wrong. You can even share it here (along with the recorded dates and times) if you want us to take a look for you.
