Microsoft confirmed an issue in the October 28, 2025 optional preview update (KB5067036) that can leave multiple Task Manager (taskmgr.exe) instances running after closing the app, potentially degrading system performance; Microsoft is investigating and provided a temporary workaround (manually ending tasks or using taskkill.exe /im taskmgr.exe /f).
