Under Windows 11, the keyboard cannot be used, and the power-on password cannot be entered.

Well, I tried to upgrade to Windows 11 but it's not supported on any of my machines, they have limited supported platforms too much, so at the moment I have no ETA on evaluating this.

Hello I use Interception Driver and it works fine for me on Windows 11.

Thanks @hyperxmason, that's good to know, so it still works on Windows 11 fine in general I think, and @ooepay's report should fall into some exceptional issue.

I had this issue on Windows 10 actually. I was testing to see if I could even install Windows 11 due to the TPM 2.0 and other requirements. So I went in the BIOS and turned it on together with everything else required.

After I done that, I discovered that I had the exact same issue the OP here has. Mouse and keyboard didn't work and I needed to go back into the BIOS to turn TPM 2.0 back off again after I forced shutdown my PC.

However, my memory is a bit hazy and it could be that it's one of the other things that need to be turned on in order to upgrade to Windows 11. In Windows 10 I turned those things on, I restarted my PC and headed into the BIOS to turn TPM 2.0 on. On the next boot is when the issue occurred.

Ps: My memory is hazy because I spend a lot of hours troubleshooting this issue and I couldn't find an solution. I ended up disabling the requirements to upgrade to Windows 11 and then I assumed Windows 11 wouldn't work because those features need to be turned on. Or at least, that's what I might've assumed incorrectly. Maybe it's fine to turn TPM 2.0 and the other things back off after the upgrade.

EDIT: I just tried it again. Current setup that works fine, went into the BIOS and turned on TPM 2.0 and Secure Boot. Upon bootup my mouse and keyboard don't work anymore. I need to press the physical button on my PC to restart.

I go back into the BIOS and turn those 2 things off again. On bootup, mouse and keyboard work. I uninstall the Interception driver.

Again in the BIOS, turn those 2 functions on again. On bootup my mouse and keyboard work fine and I can login normally.

This should be relevant, it's possible that those new secure boot functions may not be accepting the signature of the drivers, which are valid, but too old.
