Some Windows 11 users are experiencing an issue where Task Manager cannot be completely closed after installing the October optional update KB5067036. When users close Task Manager using the "X" button in the window, processes remain in the background, and each repeated operation adds a new "ghost" process, potentially causing system performance degradation.
Test data shows that after repeatedly opening and closing Task Manager 100 times, 100 residual processes accumulate in the background, each consuming 20-25MB of memory, totaling approximately 2GB of system resources. For devices with limited memory, this vulnerability can cause significant lag. Although ordinary users rarely interact with Task Manager frequently, this issue still poses a potential risk in performance debugging scenarios. Media tests on 100 virtual machines showed a 30% reproducibility rate, but Microsoft has not yet responded.
Currently, users can temporarily work around the issue with two solutions: 1) Change the closing method: right-click on the Task Manager itself in the process list and select "End Task"; 2) Forcefully terminate all related processes by executing `taskkill /im taskmgr.exe /f` in the command line. Affected users are advised to pay close attention to subsequent patches released by Microsoft.
