How to disable test mode in Windows 11

If “Test Mode” appears in the bottom right-hand corner of the Windows 11 desktop, indicating the version and build of the system, you have two ways to remove it.


Disabling test mode at the command line:

  • Run the command line as administrator, or right-click on the Start button and start Windows Terminal as administrator.
  • Enter the command “bcdedit.exe -set TESTSIGNING OFF” and press Enter.
  • Close the command line and restart the computer.


Disabling test mode using a third-party utility:

  • Download Universal Watermark Disabler.
  • Launch and press Install button
  • Confirm installation and in the next window press OK to log out.
  • When you log in again, the “Test Mode” caption will disappear from the screen – done!
