Windows 11 Test Mode

Just a little sharing, I woke up today morning and suddenly found my system Windows 11 booted-up via Test Mode. Very funny and curious because I never touched / tweaked anything yesterday before shutting down. However I managed to get rid of it via executing command prompt technique. I had no 3rdparty tools and my Windows is running smooth, Windows Update is working fine too ..

    Test Mode is typically used by developers or for testing unsigned drivers and system modifications. When enabled, it indicates system modifications or testing features are active, and Windows displays a watermark or boot indicator.

    It's interesting that your Windows 11 system unexpectedly booted into Test Mode without any intentional changes. Test Mode is typically enabled when you're running a version of Windows with unsigned drivers or if you've manually enabled developer or test signing options. Sometimes, it can also happen due to certain system updates or driver issues.
