Microsoft accidentally disabled the AI-powered Copilot assistance on certain Windows 10 and 11 PCs with the March 2025 upgrades. The firm has acknowledged the issue and is working on a fix.

Microsoft has acknowledged that the March 2025 Windows updates unintentionally disabled the AI-powered Copilot assistance from certain Windows 10 and Windows 11 PCs. Users who installed the March 11 updates KB5053598 (Windows 24H2) and KB5053606 (Windows 10 22H2) were impacted. Microsoft clarified that the Microsoft 365 Copilot app is unaffected by the inadvertent uninstalling and taskbar removal of Copilot.

On a support page, Microsoft acknowledged a problem concerning the Microsoft Copilot application that is impacting devices. The application was inadvertently uninstalled and removed from the taskbar. It is important to note that this issue has not been reported with the Microsoft 365 Copilot app. The company has not explained the removal of Copilot and has not included this issue on its Windows release health dashboard.

This is not the first instance in which Microsoft has had to eliminate a Copilot application from Windows. In June 2024, the company took down a Copilot app that had been inadvertently included in Windows 10 and 11 via a Microsoft Edge update in April. At that time, Microsoft clarified that the app neither collected nor transmitted data to its servers and was solely designed to ready devices for an upcoming Copilot deployment.

The technology giant launched the Windows update for March 2025 on March 11, 2025. This update introduces various security enhancements to the operating system's internal functions. Additionally, it improves the servicing stack, the element responsible for installing Windows updates. Updates to the servicing stack (SSU) are designed to provide a strong and dependable servicing framework, enabling your devices to effectively receive and install updates from Microsoft.
