Trying to figure out how to remove/reverse a TPM bypass from years ago. Can’t remember what I used!

Is there a way to figure out what I used and then remove/reverse whichever TPM bypass from years ago to get Windows 11 onto my PC at launch? I can’t for the life of me remember which method I used.

Turns out I do have TPM 2.0 and it just wasn’t enabled in the BIOS, and I want to get 24H2 via Windows Update but it isn’t showing up. Maybe there’s another reason but it isn’t one of the guards, I checked in my registry. Plus I’d like to prevent future issues with updates.

Would using Windows Update to reinstall my current version (but keep files and settings) be helpful, or would the bypass still be in place? I saw one person say that 24H2 showed up after doing that, but I don’t know if they had used a bypass or not.

    Performing a "Reset this PC" (using "Keep my files and settings") can sometimes clear residual bypass flags or registry tweaks.

    If you don’t remember the exact method, it’s tough to track down precisely what was done. But some common tricks involved modifying registry keys, using certain boot configurations, or disabling TPM checks via BIOS or system files.
