A recent update to Windows 11, KB5067036, has introduced a bug that causes the Task Manager to malfunction and potentially degrade system performance. When users attempt to close the Task Manager, the application may not exit properly and instead create multiple instances in the background, consuming CPU and memory resources. This issue has been confirmed by Microsoft, who are currently investigating the problem. In the meantime, users can temporarily resolve the issue by using the 'End Task' button within the Task Manager or by running the 'taskkill /im taskmgr.exe' command in the Command Prompt. This bug has been reported to affect users who have installed the KB5067036 update, and it is recommended that they take immediate action to prevent further performance degradation. The issue is likely to be resolved in a future update, but in the meantime, users should be aware of the potential risks and take steps to mitigate them.
