Microsoft's cumulative updates for Windows 10 and Windows 11 released on March 11, 2025 (KB5053598 for Windows 24H2 and KB5053606 for Windows 10 22H2) have unintentionally led to the removal of the AI-driven Copilot digital assistant from certain systems. Microsoft acknowledged the issue, stating that the Copilot app is unintentionally uninstalled and unpinned from the taskbar, but this problem does not affect the Microsoft 365 Copilot app. Microsoft has not provided a detailed explanation for the removal and has not listed this issue on its Windows release health dashboard. The company is working on a resolution and recommends affected users reinstall the app from the Microsoft Store and pin it back to the taskbar. This incident follows a previous occurrence in June 2024, where a Copilot app was retracted due to erroneous installation linked to Microsoft Edge updates. Microsoft had also introduced Copilot to select Windows Server 2025 preview builds but retracted it after pushback from administrators. Recently, Microsoft announced the rollout of a new native Copilot app to Windows Insiders, which includes a press-to-talk feature for voice commands.
