A recent Windows 11 security update is causing unexpected issues for enterprise customers, including the unintentional removal of Microsoft’s Copilot AI assistant from affected systems, creating potential workflow disruptions for organizations that have integrated the AI tool into their operations.

To put Copilot back on the Taskbar, click the Start button and look for Copilot in the Start menu or All screen. Right-click its shortcut, move to the More menu, and click Pin to Taskbar. You can then launch and use Copilot as you normally would.

A recent Windows update can actually remove Microsoft's Copilot assistant from the OS. As the company promotes generative AI to the public, Redmond accidentally introduced a software bug last week that can delete the Copilot program from PCs running Windows 10 or 11.
