A bug affecting Windows 11 24H2 and 25H2 users has been discovered where attempting to close the Task Manager inadvertently results in the spawning of additional copies of the application. This issue arises following the October update preview, leading to a situation where users unintentionally create a cascade of Task Manager processes.
Typically used to monitor and manage applications on a system, the Task Manager now presents a challenge as users struggle with its unexpected behavior. Instead of terminating the Task Manager, closing its window triggers the creation of new instances, each consuming system resources. This abnormality can potentially lead to performance degradation and increased power consumption over time.
While individual instances may not noticeably impact system performance, the accumulation of multiple processes could pose a risk, especially for users who rely heavily on the Task Manager or keep their systems running for extended periods without a reboot.
