I've been running Windows 11 since Nov 2021. This is the first update failure I've encountered. I was trying to install KB5014668. It stopped at 25% install and showed error 0x80000ffff. I ran troubleshooter (multiple times) to no avail. Upon a restart, it showed installing an update, in the middle it rebooted and then on the subsequent restart it showed install to 48% then said something went wrong, not to worry as it was restoring. It rebooted again, showing the same message, on the next restart it booted into windows. I've run sfc /scannow and dism restorehealth. Neither showed an error or helped. I use Macrium and also tried mounting an image taken before I tried the update and copied the Software Distribution folder and pasted it over the current folder. No help there either. I am able to download Windows Defender definition updates okay at this point.
I could just restore the whole drive to a point before I tried the install but would like to use that as a last resort. Right now I can perform multiple restarts with it booting straight into Windows. So I'm not sure if I should just wait until the July cumulative is available to see what happens or is there something I can or should try at this point, like try to download and install it straight from the update catalog?
Thanks for any help with this.
Update... I did try to use the Windows Catalog to do a manual install. It seemed to download ok but when I hit install it failed immediately with an error code of 0x80070002 (I got this from the reliability monitor)
