Microsoft engineers are known for their failed patches and fixes. And they’ve done it again with the Windows 11 Patch Tuesday KB5015814 July update for Windows 11 version 21H2 (via Beta News). Though it would be a minor update, it causes random app crashes and interferes with the start menu operation.
The recently released Windows 11 Patch Tuesday update KB5015814 included improvements that were part of update KB5014668, the new Search Highlights feature, fixed an issue that redirected the PowerShell command output, as well as security vulnerabilities.
However, this update seems to have caused problems for those who have downloaded and installed it on their systems, especially the Start menu. Users complain that the start menu is interrupted erratically by opening and closing an app.
Some Reddit users claim that Windows 11 PCs with Malwarebytes are likely to experience more problems with KB5015814.
“Yesterday’s Windows 11 update KB5015814 wouldn’t install until I uninstalled Malwarebytes. Tried a million things but had no success uninstalling Malwarebytes‘ said one Reddit user.
While there are some Redditors who have claimed that the update fails to install, there are also complaints about errors that occur after a failed installation of the KB5015814 update with error codes such as 0x8000ffff, 0x800f0900, 0x8007007e, and 0x80073701. Some Windows 11 PCs, which were unable to install the update, have also been stuck in a boot loop.
“I keep getting an installation error 0x8000ffff with this update even after restarting the computer. I’m not sure if I installed KB5014668 because I don’t see it in the update list‘ wrote one of the affected users on the Reddit forum.
“I’m on windows 11 by the way. This is kind of weird because there was a security update that installed just fine, but it still won’t install: 2022-07 Cumulative Update for Windows 11 for x64-based Systems (KB5015814) Installation Error – 0x800f0900
“2022-06 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 11 for x64 (KB5013889) Installation Error – 0x800f0900‘ commented another user.
“Something is wrong with this update, a boot loop has occurred. Fortunately, Windows managed to unlink itself. Recommend not to install it‘ wrote a third user.
Microsoft has not updated the changelogs for this latest patch to mention Start menu issues, failed installations, or the above error codes. It has yet to officially acknowledge these new issues reported by users.
Since the update KB5015814 is installed automatically without user intervention, the only solution to this issue is to pause Windows updates to skip it for now or remove the security update.
To uninstall the Windows 11 KB5015814 update, you need to go to Settings app > Update & security > Windows Update > View update history > Uninstall updates (select KB5015814) to fix the issue.
It is important to note that KB5015814 is a security update. Since there is no clarity on how widespread the problem is, it is recommended that you only uninstall update KB5015814 if you are experiencing issues.
