I use Windows 11 Home on my PC.

Today I see "Test Mode Windows 11 Home Build 26100.ge_release.240331-1435" in the lower right-hand corner of my display. Have never had this message before.

You would normally see "Test Mode" like that when disabling driver signature enforcement. You can just enable it again. A reboot should automatically disable the driver signature bypass. If not, try this.

Reboot your PC and hit F7 (might differ depending on your board manufacturer) during the boot progress.

• Click/tap on Troubleshoot on the Choose an option screen at boot.

• Click/tap on Advanced options in Troubleshoot options.

• Click/tap on Startup Settings in Advanced options.

• Click/tap on the Restart button in Startup Settings.

• When the computer restarts into Startup Settings, press the 7 or F7 key to Disable/enable driver signature enforcement.

Option 2

Enable or Disable Driver Signature Enforcement in Command Prompt

It is required to disable Secure Boot if you get the error message below while trying to enable Test Mode.

An error has occurred setting the element data.
The value is protected by Secure Boot policy and cannot be modified or deleted.

Open an command prompt in admin mode.

Copy and paste the command you want to use below into the elevated command prompt, and press Enter.
Enable driver signature enforcement - DEFAULT
bcdedit /set nointegritychecks off

OR
Disable driver signature enforcement
bcdedit /set nointegritychecks on

Reboot your PC.

THANK YOU! Option 2 did the trick.
