Microsoft fixes Windows Task Manager bug hurting performance

⚠️ Microsoft released a fix for a Windows 11 Task Manager issue introduced by the optional preview update KB5067036 that could leave multiple taskmgr.exe processes running after the window was closed. The defect, blamed for stuttering and CPU hangs on affected systems, is resolved in the November cumulative security update KB5068861. Microsoft recommends installing KB5068861, and users who cannot immediately update can temporarily terminate lingering Task Manager processes by running an elevated Command Prompt and executing taskkill.exe /im taskmgr.exe /f.

Windows Task Manager Won't Quit After KB5067036 Update

⚠️ Microsoft confirmed a known issue where closing Task Manager does not terminate the taskmgr.exe process after installing the October 28, 2025 preview update (KB5067036). Multiple background instances can consume CPU and cause stutters. As a temporary workaround, end each process in a new Task Manager window or run: taskkill.exe /im taskmgr.exe /f while Microsoft investigates a permanent fix.
