UPDATED 11/4/2023: On Windows 11, after installing the update KB5031455, it’s possible to uninstall it if it’s causing problems as a result of a bug or compatibility issues or if you want to stay on the same version for a little longer.
Since the update that brings the new Copilot and many other features, the new Windows Backup app, AI updates for Paint, Photos, Snipping Tool, and Clipchamp, a redesigned version of File Explorer, and more, is a cumulative update similar to those the system downloads every month, you can uninstall it at any time from the “Windows Update” settings as long as another update supersedes the previous update.
If there’s a problem with the update and the computer can start normally, you can also use the Windows Recovery Environment (WinRE) to remove the update KB5031455 from Windows 11.
These are non-destructive methods, meaning you won’t lose your files, apps, or settings during the process. However, it’s always recommended to have a backup of your files.
