Windows Upgrade Help and more

That's a really frustrating situation, especially when you're sure you didn't mistype the PIN. Let's work through some diagnostic steps to figure out the "why" and get you back in.

First, the most common culprit is a recent firmware (BIOS/UEFI) or Windows update that changed a TPM-related setting ...

This. I had the same problem with my ASUS board. I had to go into the BIOS and enable both the TPM setting and a separate setting called "PTT" or "fTPM" to get it working.

Same here. This happened to me too. I had to manually enable fTPM in the BIOS before the checker would see it.

Another option is to make sure Auto HDR is enabled, since it gives better color and contrast in many games that weren't originally designed for HDR.
