Windows 11's latest preview update, patch KB5067036, has introduced a bug in Task Manager that may affect system performance. This issue keeps Task Manager running in the background even when closed, potentially consuming system resources.

The problem arises when clicking the X does not terminate Task Manager, causing multiple instances to open. Each instance uses CPU and memory power, which can slow down performance. A recommended fix involves manually closing instances through Task Manager itself or using the Command Prompt command:
Update Caution and Recommendations
Due to this problem, and scattered reports of failed installations and even system malfunctions, users should approach the optional preview update cautiously. Microsoft has yet to officially acknowledge this bug, but is expected to address it in the upcoming full release.
For those who prioritize system stability, delaying the installation of this update could be wise. Alternatively, using available methods to manage Task Manager instances effectively can help maintain system performance until the official fix is released.
