A bug in the latest Windows 11 update automatically uninstalls Copilot and unpins it from the taskbar.The bug affects certain installs of Windows 11 and Windows 10 when specific updates are installed.Microsoft is aware of the issue and is working on a resolution, but affected users can reinstall Copilot manually.While Copilot may have its uses, the bug is seen as somewhat counterintuitive to Microsoft's AI PC vision.
