How to Disable Fast User Switching Using Regedit

Disabling Fast User Switching in Windows prevents multiple users from staying logged in at the same time, saving system resources and improving security on shared computers. This article provides a direct, step-by-step guide on how to modify the Windows Registry (regedit) to disable the Fast User Switching feature across all local accounts on your system.

Steps to Disable Fast User Switching

  1. Open the Registry Editor
    • Press Windows Key + R to open the Run dialog.
    • Type regedit and press Enter or click OK.
    • Click Yes if prompted by User Account Control (UAC).
  2. Navigate to the Policies Key

    • In the address bar at the top of the Registry Editor, paste the following path and press Enter:

      HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

    • Alternatively, use the left navigation pane to browse to that location manually.

  3. Create the Configuration Value
    • Check the right-hand pane for a value named HideFastUserSwitching.
    • If it does not exist:
      • Right-click any empty space in the right pane.
      • Select New > DWORD (32-bit) Value.
      • Name the new value HideFastUserSwitching and press Enter.
  4. Modify the Value Data
    • Double-click HideFastUserSwitching.
    • Set the Value data field to 1.
    • Ensure the Base is set to Hexadecimal.
    • Click OK to save the changes.
  5. Apply the Changes
    • Close the Registry Editor.
    • Restart your computer or sign out of your account for the changes to take effect.

Once restarted, the option to switch users from the Start menu, the Lock screen, and the Ctrl + Alt + Delete menu will be hidden. To restore Fast User Switching in the future, return to the same registry key and change the value data of HideFastUserSwitching back to 0 or delete the entry entirely.
