Cumulative Update for Windows 11 (10.0.22000.100) (KB5004300) - Error 0x800f0900
Run Windows Update troubleshooter from Settings app > System > Troubleshoot > Additional troubleshooters.
Let us know what it reports back.
- Prabakaran_KNJul 28, 2021Brass ContributorHello,
I tried running Windows Update Troubleshooter, it reported me " Windows Update " and then an error symbol, I clicked next and it started displaying " Resolving problems " but it didn't help. - BriggieJul 28, 2021Copper Contributor
So tried sfc /scannow and it says there were corrupt files, but was unable to fix them. It points me to the path of the cbs.log file which I have attached.

Briggie, try these steps:
1. Search for 'windows powershell' using Cortana or Windows Search.
2. From results, choose Windows PowerShell and select Run as administrator.
3. Then type/paste following and press Enter key:
Repair-WindowsImage -Online -RestoreHealth
4. Let the command complete, restart your system then.
Let us know if this helps!

How to restart Windows Update Service ? and will it cause me to leave the Insider Program ?
- BriggieJul 28, 2021Copper Contributor
Yep I run it and it has me try:
net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc
Some of these weren't running anyway so I proceeded with:
Del “%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat”
Which then throws an error saying:
Could Not Find C:\ProgramData\Application Data\Microsoft\Network\Downloader\qmgr*.dat
I also tried the commands in here:

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
These did not resolve the issue either.
