Ugh, so frustrated. My work PC (HP ProDesk 400 G3) won't take the Win 11 upgrade

+1 You could also try using the official Microsoft PC Health Check app to see exactly which requirement you're missing. Another option is checking if HP has released a specific BIOS update for your model that enables full Windows 11 support. Hope that helps.

Yeah, and sometimes you can manually enable TPM 2.0 and Secure Boot in the BIOS if they're off, which might get you past that check.

Agreed. You could also check if your IT department has any approved workarounds or exceptions for upgrading older work machines.

+1 I had the same problem with an older Dell at my office. My IT guy ended up pushing the upgrade through for me using their management tools.

+1 This happened to me on a similar model. I ended up having to enable TPM 2.0 and Secure Boot in the BIOS before it would go through.

I had the same problem. Even after enabling TPM and Secure Boot, my old i5 needed a specific BIOS update from HP before the installer would finally accept it.

+1 Did you also check if your BIOS is set to UEFI mode and not Legacy? Let me know if that works.

Can confirm. Yeah, that's a solid point. Also, double-check that Secure Boot is actually enabled in the BIOS, not just available.

Yeah, And while you're in there, make sure TPM 2.0 is enabled as well, it's a common trip-up. Good luck!

Same here. You could also check if your PC is on the latest BIOS version from HP, as that sometimes adds support. Let me know if that works.
