Microsoft has claimed that one long-running camera issue in Windows 11 24H2 have been resolved in the latest Windows 11 monthly update. After update (KB5067036), you might encounter an issue where closing Task Manager using the Close (X) button does not fully terminate the process. Now this issue is resolved with the latest update.

After installing Windows Updates released on or after October 28, 2025 (KB5067036), you might encounter an issue where closing Task Manager using the Close (X) button does not fully terminate the process. When you reopen Task Manager, the previous instance continues running in the background even though no window is visible. This results in multiple lingering instances of taskmgr.exe, consuming system resources and potentially degrading device performance. Additional instances appear as “Task Manager” in the Processes tab and as “Taskmgr.exe” in the Details tab. Although the impact is less if Task Manager is opened and closed a few times, many instances accumulated over time can cause noticeable slowdowns in other applications.

Resolution:

This issue is resolved in the November Windows security update (KB5068861) and later updates. We recommend you install the latest update for your device as it contains important improvements and issue resolutions, including this one.

If you have installed Windows updates released before November 11, 2025, you can use the following workaround.

Workaround: You can mitigate the issue by following one of the steps below:

When closing Task Manager, instead of closing it with the ‘X’ button, use End Task on the Task Manager process itself. This can be done by going to the Processes tab, selecting the Task Manager process, and clicking End Task.
To close multiple instances of Task Manager, you can use the command line prompt:
Click Start (Windows icon) or press the Windows key.
Type cmd or Command Prompt in the search box.
Click Command Prompt from the results.
To run as Administrator: Right-click Command Prompt and select Run as administrator.
Run the command taskkill.exe /im taskmgr.exe /f and press enter.
This will close all instances of Task Manager
