What is Test Mode in Windows?
Test Mode is a special boot configuration in Windows that lets users install unsigned drivers — usually used for development or testing. When enabled, Windows shows a “Test Mode” message in the bottom-right corner of your desktop.
This fix restores default driver signature enforcement, which removes the watermark and brings Windows back to normal mode.
Steps to Disable Test Mode:
1.Open Command Prompt as Administrator
2.Type the first command and press Enter
bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS
2. Type the second command and press Enter
bcdedit.exe -set TESTSIGNING OFF
3.Close the Command Prompt window
4.Restart your PC
Once your PC reboots, the Test Mode watermark should be gone.
Steps to Disable Test Mode:
1.Open Command Prompt as Administrator
bcdedit /set testsigning on
paste this command and hit Enter Restart your PC and done
