How to Activate Task Manager When It's Not Responding 

Most Windows users have complained about the 100% disk usage error and the not opening error of the Task Manager. The best feature of Task Manager is that you can force close or kill any unresponsive apps or programs just with a single click. However, in this case, the Task Manager itself stops responding. As this case is very frustrating, it is of vital importance that you fix it as soon as possible. 

Here are few solutions to fix the Task Manager not responding issue. You can pick any of the ways selectively and use it. Before moving to the solutions, I suggest you do the most obvious thing (in case you haven’t done it already). Do a quick restart and try launching Task Manager. Now let’s move to the solutions.

Solution 1. Upgrade Windows to the Newest Version

When a lot of users face a certain issue, Microsoft launches a new update to fix it permanently. It might be possible that Windows has an update available to resolve your issue too.

Here are three methods to enable Task Manager, follow them and fix the not opening or responding error.

Windows Registry is a powerful tool and making modifications in data entries you don’t know about could damage your PC. Be extra careful and follow the steps carefully.

2. Once in the registry editor, navigate to the following file path using the left navigation pane:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\System

3. If the System key is not there, you will need to create it. We will show you how to create the entire registry after this.

4. Locate "DisableTaskmgr" from the list of items present. Double click it and enter the value as 0. Press OK.

5. Restart your computer and check if the problem gets solved.

If you don't have the registry present and the file path only goes till Policies, we can try creating the registry and implementing the changes needed.

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System  /v  DisableTaskMgr  /t REG_DWORD  /d /0 /f

3. The process might take a while as Windows is checking all your files and looking for discrepancies. Wait till the process is completely finished. Once it has finished and there were errors detected, restart your computer and check if the problem got fixed.

If you are unfamiliar with manually editing the CMD, you can create a Registry file which will automatically modify the Registry Key to re-enable Task Managing. 

1. Open Notepad or any other text editor.

2. Copy the code given below and paste it as it is in it.

Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System] “DisableTaskMgr” =dword:00000000

3. Save the file as Enable Task Manager.reg or *.reg.

4. Open the file by double-clicking on it.
