0x800f0991 critical update KB5065786 (26220.6690 ) goes so far then says retry

Answer 1

Hello, thank you for reaching out to Microsoft Q&A.

You are on a Insider build 26220.6690 (Dev Channel) released September 19, 2025. Open Command Prompt as Administrator and run these commands one by one:

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren %systemroot%\softwaredistribution softwaredistribution.bak
ren %systemroot%\system32\catroot2 catroot2.bak
net start wuauserv 
net start cryptSvc 
net start bits 
net start msiserver

If the issue persists, try doing an in-place upgrade. You can do this by downloading the latest ISO file from the Windows Insider ISO page and running the setup directly from it.

Let me know if you still need more help.
