Windows update unintentionally uninstalls Microsoft Copilot app

Microsoft's recent security update for Windows 10 and 11 has caused significant issues, described as a "nightmare" for users. The update unintentionally uninstalls the Microsoft Copilot app, affecting many devices. Microsoft is working on a fix but advises users to reinstall the app from the Microsoft Store and pin it manually to the taskbar. This situation is ironic, as Copilot was automatically installed on devices. Additionally, some users have reported installation problems, including the blue screen of death. The update is mandatory, but users may need to pause it to maintain normal PC operation until the issues are resolved.
