KB5015882 fails to install for many:

Many Users (1, 2, 3) have reported in the official forum that the update KB5015882 fails to install for them. The update download gets stuck and doesn’t install further for some, while some users don’t succeed in installing it after downloading.

Windows 11 July 21 Update KB5015882 fails to install (Error code: 0x800f0922)


I’m trying to install the most recent Windows 11 update (KB5015882). The update downloads and begins to install and restarts my computer. After the restart the installation continues until it reaches 96%. Then it fails with the message “Something didn’t go as planned. Don’t worry we are undoing changes.” When checking the WIndows Update activity, I see error code 0x800f0922.

I’m running an x64 AMD rig.

Any ideas on how I can fix this? Or should I just wait this update out?

Windows 11 Update KB5015882 fails with error code 0x8000ffff

Second time in a row now with a Windows 11 Update and exactly the same error code of 0x8000ffff. Had the same error code with the previous update.

However, this time the issue is affecting both my PCs and both with the same error code.

Never had a problem before.

Absolutely fed up with this nonsense which has wasted most of the day trying to get the updates to install on my two systems, without success.

How do I fix it?

Update KB5015882 continuously fails installing

I’m at my wits end with this update now. It keeps failing to install at 25% citing 0x8000ffff error code.

I’ve tested a number of things. SFC finds no issues that need fixing, I’ve restarted the Microsoft Store via WSReset.exe, I’ve run the Windows Update troubleshooter but it it did not fix the issue either.

I’ve got plenty of disk space free as well so that’s not the issue either.

When I reboot, it tries installing the update but then repeatedly says something went wrong and then proceeds to rolling back. This has occurred consecutively for three days in a row now.
