Recently, some users have happened to enter system's test mode after upgrading to Windows 11. It is upset that there is a watermark on the bottom right corner of screen.

Incompatible drivers or applications may result in entering test mode. It is a special system mode that allows developers to install and run drivers or applications without digital signature for development or test. Unsigned applications, however, increase the security risk to the system and reduce its stability if you don't disable test mode.

Therefore, this article will illustrate how to disable test mode in Windows 11 with two practical methods.

• Method 1: Disable test mode with "set testsigning off" command line
• Method 2: Disable test mode with "set nointegritychecks off" command line

Step 3: This operation has been finished if you get the following message.

Step 4: Click Restart button to reboot your computer and you have exited the test mode when you enter system again.

Method 2: Disable test mode with "set nointegritychecks off" command line
