Windows Task Manager not responding or opening
Jun 30, 2025 pm 05:08 PMWhen the task manager cannot be opened or stuck, you can try the following steps to solve it: 1. Check whether the system resources are overloaded, press Ctrl Shift Esc or Ctrl Alt Del to try to open and close the high-occupancy program; 2. Force start with the command line, enter cmd during runtime and execute start taskmgr; 3. Check whether it is disabled, modify the DisableTaskMgr value to 0 through gpedit.msc or the registry; 4. Run the sfc /scannow and DISM commands to repair the system files and restart the computer.
The task manager cannot be opened or stuck is a common problem for Windows users. It may occur suddenly, affecting the troubleshooting system resource occupation and ending process operations. Don't worry, this situation is mostly solved.

1. Check whether the system resources are overloaded
First, the task manager itself is also a program. If the system is already very stuttering (such as CPU or memory usage is close to 100%), it may not start properly or be unresponsive after being turned on.

You can try the following:
- Press
Ctrl Shift Esc
to open the task manager directly (shortcuts are faster than from the right-click menu) - If it is invalid, press
Ctrl Alt Del
and select Task Manager - If it still doesn't respond, try restarting a program with high resource occupancy first, especially when the browser opens multiple tabs, it is easy to drag down the system.
2. Force start Task Manager with the command line
Sometimes the graphical interface cannot be accessed, so you can use the command prompt to handle it:

Press
Win R
to open the running windowEnter
cmd
to enter-
Enter:
start taskmgr
This can bypass some graphical interface loading problems. If that doesn't work, it may be that the task manager is disabled (such as Group Policy Restrictions).
3. Check whether the task manager is disabled
Some company computers or controlled devices will ban Task Manager through Group Policy, and you will see a prompt that "Task Manager has been disabled by the system administrator".
If you are an administrator of the computer, you can modify it back through the registry or group policy:
- Press
Win R
and entergpedit.msc
to enter (only available in professional and above systems) - Path:
用戶配置> 管理模板> 系統(tǒng)> Ctrl Alt Del 選項(xiàng)
- Check whether the "Don't Allow Task Manager" is enabled, if so, change to "Unconfigured" or "Disabled"
If it is a home version system, you can use the Registry Editor:
- Press
Win R
and enterregedit
- Navigate to
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
- Check whether there is
DisableTaskMgr
item. If the value is 1, it means it is disabled. Change it to 0.
4. System file corruption may also cause problems
If none of the above methods work, it may be that the system file is corrupted. You can use the system's own tools to check and repair:
- Open the command prompt as an administrator (right-click Start Menu → Windows Terminal (Admin))
- Run the following commands in turn:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
These two commands scan and repair system critical files. After completion, restart the computer and try Task Manager.
Basically, these common causes and solutions. Some situations can be restored after restarting, but if they do not happen frequently and suddenly appear, it is recommended to check whether there are any malware or driver conflicts.
