Question

Hello all;

Mon Oct 20 11:30 PM EDT I checked for updates and found 2 available 1 for Security Intelligence Update for Defender which was successful

and

Install Cumulative Update for Windows 11 25H2 (KB5070773) (26200.6901) which failed twice, Install error 0X8000ffff.

Then I reboot the PC and am currently trying third install, but it looks like another failure. Stuck at 8 % for 10 minutes now.

Will update as soon as finished as to success or failure.

Right now Installing 0 %

Hi, I'm Bernard, a fellow Windows user. I'm happy to help!

I understand the issue you have, there is nothing to worry I am here to assist. The error 0X8000ffff is a system corruption error. If the update fails, kindly follow the steps below:

Reset Windows Update components:

Open Terminal (Admin) or Windows PowerShell(Admin) (Press Windows key + X then click Terminal(Admin))

Copy each line of command, then press enter (one line at a time)

net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc
Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"
rmdir %systemroot%\SoftwareDistribution /S /Q
rmdir %systemroot%\system32\catroot2 /S /Q
regsvr32.exe /s atl.dll
regsvr32.exe /s urlmon.dll
regsvr32.exe /s mshtml.dll
netsh winsock reset
netsh winsock reset proxy
net start bits
net start wuauserv
net start appidsvc
net start cryptsvc

-Once done restart the device and check.

If none will work from the above solution, I suggest doing an in-place upgrade wherein it will update the device to the latest version and repair all issues without deleting any files.

Answer 2

Hi, thank you for that information. Yes, it is either you wait for another update or do the last step, which is the in-place upgrade to push the update. However, I recommend waiting for another update instead.

The following pictures speak volumes for the results I had from following your advice.

I aborted after 3rd failure, exited and started a system restore that took 30 minutes to complete.

So I guess I will just wait until next month, pause for 4 weeks the Windows Update and see what happens from there.
