NoPilot: Microsoft is notorious for routinely bringing Windows usability and reliability to a halt with every other patch cycle. The latest updates released in March included the accidental bonus side effect of removing Copilot from Windows systems, and Redmond has yet to explain why.
On March 17, Microsoft released the KB5053598 update for Windows 11, bringing the OS build number to 26100.3476 and introducing the usual batch of changes and security updates. As Windows users have come to expect, each new Patch Tuesday can be both a security improvement and a potential disaster for OS stability.
Security-wise, the KB5053598 update addresses 57 flaws, including seven zero-day vulnerabilities. However, the most surprising "feature" of this update is that it unintentionally uninstalls the Microsoft Copilot application on some devices. Copilot is removed from the system and unpinned from the taskbar, according to Microsoft. However, the issue does not appear to affect the Microsoft 365 Copilot app.
While Microsoft is working on a fix, affected users are advised to download and reinstall Copilot from the official Microsoft Store. Manually pinning the app to the taskbar should restore the chatbot functionality.
Microsoft Copilot's disappearance is just one of three outstanding issues acknowledged by Microsoft for the KB5053598 update. The other known problems include Roblox no longer working on Arm devices and installation failures on systems with certain Citrix components.
Beyond Microsoft's officially listed issues, users are reporting additional problems with the update. In some cases, the update fails to install, generating various error codes, including 0x800f0993, 0x800F081F, 0x80070032, and 0xC004F211.
Even when the update installs successfully, users may encounter post-installation issues. These include Remote Desktop Protocol disconnections, kernel or critical error messages, Blue Screens of Death (BSODs), and more. In the worst cases, some users have found themselves unable to boot their systems after installing KB5053598.
As with the Copilot issue, affected users can attempt to restore system stability by manually uninstalling the KB5053598 update.
Microsoft appears increasingly disinterested in providing a reliable PC operating system, as its focus shifts toward selling AI services and cloud subscriptions (or showing ads). Perhaps that explains why powerful hacking tools remain freely available on GitHub, with no censorship or restriction in sight.
