Run Task Manager as admin Windows Server 2012

Task Manager in Windows Vista and Windows 7 runs in non-elevated mode by default, showing only those processes running under the current user context. To be able to terminate or manage a process running under other user accounts, or to log off other users, you need to elevate Task Manager by clicking the Show processes from all users button in the Processes tab.

Alternately, you can create a desktop shortcut to Taskmgr.exe, right-click on the shortcut and click Run as administrator. But, this workaround won’t help if you mostly use the Ctrl + Shift + Esc keystroke to launch the Task Manager.

I’ve just found a way to start Task Manager in elevated mode by default when using the Ctrl + Shift + Esc keystroke or when running Taskmgr.exe directly, and sharing the knowledge in this post. The trick is to set the Debugger registry value for Taskmgr.exe, pointing to a VBScript which starts Task Manager elevated. The method which I found works perfectly fine, no matter which way you use to launch Task Manager.

Here are the instructions to make Task Manager always start in elevated mode:

1. Open the C:\Windows\System32 folder.
2. Make a copy of Taskmgr.exe and name the copy as Taskmgr2.exe
3. Download taskmgr-elev.zip and unzip the contents to a folder
4. Move the file taskmgr.vbs to C:\Windows
5. Double-click taskmgr-elev.reg to run it
6. Press Ctrl + Shift + Esc, or type taskmgr.exe in Start Orb to open Task Manager. It should now show the User Account Control elevation dialog. Click Continue so that Task Manager runs as administrator (elevated). And, when you run Task Manager from a standard user account, it should prompt for administrator credentials.

More Information

The registry fix above sets taskmgr.vbs as the Debugger for taskmgr.exe process, by writing to the following key:

Starting Task Manager will now invoke the script file taskmgr.vbs, which then launches taskmgr2.exe elevated. To reverse the changes, run the Undo.reg file, and then manually delete taskmgr.vbs from the Windows directory.

The excellent Process Explorer utility uses the same technique to replace Task Manager.
