Cumulative Update for Windows 11 (10.0.22000.100) (KB5004300) - Error 0x800f0900
Been getting this error since I first installed the preview build. Error 0x800f0900. Anyone else with this issue?
- I am not very sure about that. i dont like the idea that you dont require an restart to update/upgrade to a new version of Win11. I feel this could create more issues then fix them in the long run.
I wouldn't recommend doing this at all
Yeah this one happens on windows 8.x and other versions of windows. Dont know why it occurs, but is annoying when it does.

net start bits

net start cryptsvcThis does not help me. Can you check the attached event viewer log to understand what the problem is.
- Iran all of that and error still shows up when try to update.
Yes I too ran it, it didn't work the error still pops up.
I am also facing the same problems and none of the solutions seems to work for me. If a Microsoft technician sees this reply I am willing to share all the logs required to you for solving this problem.
- Hello,
Run Windows Update troubleshooter from Settings app > System > Troubleshoot > Additional troubleshooters.
Let us know what it reports back.- Hello,
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.

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!
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:
Windows update fails with Error 0x800f0900 - Microsoft Community
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.
