Restore the Old Task Manager in Windows 11 22H2

Windows 11 version 22H2 (and above) comes with a redesigned Task Manager. The new Task Manager has additional features, such as a new command bar, UI matching the system-wide theme, Efficiency mode to limit the resource usage of a process, etc.

However, the menu bar has been removed in the new Task Manager. This is a big letdown for those who rely heavily on keyboard shortcuts.

In the old Task Manager interface, you could press Alt + F and then press Enter to start a new task. The hotkey is now changed; it’s now Alt + N. Though it’s one keypress less, it takes time to get used to it, mainly since we’ve been accustomed to the old interface for years.

Let’s see how to get back the older (21H2) version of Task Manager in Windows 11 22H2 and above.

Get Back Legacy TaskMgr in Windows 11 22H2

To get back the old version of Task Manager in Windows 11, try these steps:

Replacing Task Manager using Script

Download Old_Taskmgr.zip and extract the files to a folder.

The archive contains the following items: (See File Details & the Hash Checksum for each file.)

• Taskmgr.exe.mui
• Taskmgr.exe
• Taskmgr.exe.mun
• replace_taskmgr.vbs
• undo.vbs

Double-click the VBScript file “replace_taskmgr.vbs“. This script file copies Taskmgr.* files as Taskmgr2.* under the following directory and subdirectories:

C:\Program Files\Classic Apps\Task Manager

That’s it! The Task Manager is now replaced with its older (21H2) version.

The script also adds the debugger registry entry for Taskmgr.exe so launching the original Task Manager (Taskmgr.exe) will launch the legacy Task Manager (Taskmgr2.exe) instead. It works for Ctrl + Shift + Esc as well. If you wish to revert to the original Task Manager, run the Undo script (“undo.vbs”.)

Replacing Task Manager manually

To replace Task Manager manually instead of using the script, follow these steps:

Step 1: Copy files

1. Download Old_Taskmgr.zip and extract the files to a folder.
2. Rename all the Taskmgr.* files to Taskmgr2.* — E.g., Taskmgr.exe to Taskmgr2.exe.
3. Create the following directories:

   C:\Program Files\Classic Apps\Task Manager\Program
   C:\Program Files\Classic Apps\Task Manager\Program\en-US
   C:\Program Files\Classic Apps\Task Manager\System Resources

4. Copy Taskmgr2.exe to:

   C:\Program Files\Classic Apps\Task Manager\Program

   

5. Copy Taskmgr.exe2.mui to:

   C:\Program Files\Classic Apps\Task Manager\Program\en-US

6. Copy Taskmgr.exe2.mun to:

   C:\Program Files\Classic Apps\Task Manager\System Resources

Step 2: Replace Taskmgr.exe in the registry

1. Launch regedit.exe and go to the following location:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

2. Create a subkey named “taskmgr.exe” if it doesn’t already exist.
3. Next, create a “Debugger” string value in the right pane.
4. Double-click “Debugger” and type the path to Taskmgr2.exe within double quotes.
   
5. Exit the Registry Editor.

That’s it. Task Manager has been replaced now.
