Windows 10: Post-Windows update: Windows reports no product key was found on my device.

Hey all,Having some trouble with my Windows 11 Home. I updated my PC last night, and I noticed after an hour or so a watermark appeared telling me to buy a Windows license. The watermark also disappears on a shutdown or restart, but reappears after some time. I went into my Activation settings, and Windows now reports I have no product key for this device. I've had the computer since 2023 with no issues of the sort, and my purchase email of the computer itself shows that PC came with Windows 11 Home OED. I've tried checking my product key in cmd, but it returns nothing. No error message, liter

Windows Product Key

A friend of mine has an all-in-one that came with Windows 8 pre-installed. He erased the original OS thinking he could install another version of Windows 8. One thing he encountered, that he didn't expect, the BIOS/UEFI has a password. So, basically he is locked out from installing another OS. His BIOS has the product key nestled inside. Is it possible to find out which version the product key belong to?

I don't think that tool asks for a key if you are running the version of Windows you are trying to download the ISO for.

That looks like the Windows Key to me. I wouldn't be advertising it *Wink
