Enabling Task Manager disabled by Administrator or Virus [Trick: Windows]

Windows Task Manager is used to view details about processes running on your computer. It can be used to terminate programs that are misbehaving. Most spyware and viruses disable it to prevent themselves from being closed through it. Some administrators also disable Task Manager to prevent other users from closing important security programs like antiviruses and anti-malwares.

In such situations, running the Task Manager will give the "Task Manager has been disabled by Administrator" error. However, there are some tricks you can use to re-enable task manager and close those harmful programs manually.


Enable Task Manager from Registry in Windows10, Windows 8/8.1, 7, XP or Vista

Registry Editor can be used to modify registry keys which tell Windows how it should work. A simple registry modification can be used to bypass the Task Manager block. To do so, just follow the steps:-
  1. Click on Start. Go to Run. If you use Windows 10, Windows 8/8.1, Windows 7 or Windows Vista, go to Search.
  2. Type regedit and press Enter. Registry Editor will start. If Registry Editor is also disabled, you will first need to enable registry editing.
  3. Through the left hand navigation pane, navigate to HKEY_CURRENT_USER\Software\Microsoft\ Windows\ Current Version\Policies\System. If the System key is not there, you will need to create it.
  4. In the work area, locate "DisableTaskMgr". If this value is not there, you will need to create a new DWORD value called DisableTaskMgr. Double click on it. A window will pop up.
  5. Enter its value data as 0 and press OK.
  6. Close Registry Editor.
  7. If Task Manager is still disabled, restart your PC.

Enable Task Manager from the Group Policy Editor (Gpedit.msc)

Group Policy Editor is a feature in Windows which is used to edit local policy settings. It can also be used to enable Task Manager. To do so, just follow the steps given below:-
  1. Open Start Menu. Windows XP users click on Run. Windows 10, Windows 8/8.1, Windows 7 and Vista users, go to Search.
  2. Type gpedit.msc and press Enter. Group Policy Editor Window will show up.
  3. From the navigational pane at the left hand side, go to: User Configuration>Administrative Templates>System>Ctrl+Alt+Del Options.
  4. In the work area, double click on "Remove Task Manager" and set its value to Disabled or Not Configured.
  5. Restart your Computer or Log Off and Log back On to apply the changes.
Note : Group Policy Editor is not available on home editions of Windows.

Enable Task Manager by Running a CMD Command

Command Prompt can also be used to directly enable Task Manager.
  1. Open Notepad.
  2. Copy the code given below and paste it.
  3. REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System  /v  DisableTaskMgr  /t REG_DWORD  /d /0 /f
  4. Save the File as TaskManager.bat.
  5. Run TaskManager.bat as Administrator if you use Windwos10, Windows 8/8.1, Windows 7 or Windows Vista. In Windows XP, simply open the file. A command prompt window will flash for a second and then disappear indicating successful execution.
  6. If Task Manager is still not available, restart your PC.
The tricks mentioned will work on Windows 10, Windows 8/8.1, Windows 7, Windows XP and Windows Vista
