Windows 11 Bug Duplicates Task Manager When Closing
▼ Summary
– A bug in the optional Windows 11 KB5067036 update causes Task Manager to duplicate itself when users try to close it, impacting computer performance.
– The bug breaks the “X” button, preventing Task Manager from shutting down and causing it to run multiple instances in the background.
– Microsoft’s update notes mention a fix for Task Manager grouping issues but do not acknowledge this new bug at the time of writing.
– A temporary workaround involves closing individual Task Manager instances by selecting the “End task” button instead of the “X” button.
– Users can also run “taskkill /im taskmgr.exe /f” in the Command Prompt to shut down all Task Manager instances at once.
A recently identified bug in an optional Windows 11 update is causing the Task Manager to duplicate itself when users try to close the application, potentially impacting system performance. Reports from Reddit users and tech journalists confirm the issue is linked to the KB5067836 update, which interferes with the standard window closing process.
The problem specifically affects the “X” button in the top-right corner of the Task Manager window. Instead of properly terminating the application, clicking this button leaves the process running in the background. Each subsequent attempt to open and close Task Manager creates additional instances, gradually consuming valuable CPU and memory resources that could otherwise be used by active programs.
Microsoft’s official documentation for the KB5067836 update mentions only one Task Manager-related fix concerning application grouping with processes. The company has not yet officially acknowledged this duplication glitch, and their update documentation still states no known issues exist with this particular release. Technology outlets have contacted Microsoft for clarification about when a permanent solution might become available.
Fortunately, affected users have discovered effective temporary solutions. Rather than using the malfunctioning “X” button, individuals can select the “End task” button within the Task Manager interface itself to properly close each instance. For those dealing with multiple duplicated windows, running the command “taskkill /im taskmgr.exe /f” through Windows 11 Command Prompt will terminate all Task Manager processes simultaneously, restoring normal system operation until Microsoft releases an official patch.
