KB5015814 update is causing Start menu problems and 0x8007007e errors in Windows 11
The release of the KB5015814 update for Windows 11 earlier this week was supposed to fix problems with PowerShell as well as addressing security issues. But as has become disturbingly common, there have also been unwanted side effects for those who jumped on the update and installed it as soon as it was offered up.
Some users are experiencing problems with the Start menu, with complaints indicating that the menu is being interrupted by an app opening and closing. There are also complaints about errors appearing after a failed installation of the KB5015814 update -- specifically error codes 0x8000ffff, 0x8007007e and 0x80073701.
