Ugh, so my work PC (HP ProDesk 400 G3) is supposedly "compatible" but the Window?

Ugh, so my work PC (HP ProDesk 400 G3) is supposedly "compatible" but the Windows 11 installer keeps blocking me! The setup just stops and throws this error:

**"This PC doesn't meet the minimum system requirements for running Windows 11."**

It's so vague! I ran the PC Health Check and it says I'm good on RAM and storage. The TPM 2.0 thing is enabled in the BIOS, I triple-checked! Secure Boot is on. What else does it want from me?? This is so frustrating. Anyone else hit this wall with this model? Ready to just give up and stay on Win 10 forever.

Hey there, that's super frustrating, especially when you've checked the big boxes like TPM 2.0 and Secure Boot. The HP ProDesk 400 G3 is right on the compatibility edge, so a few other things often trip it up.

First, let's double-check the **CPU generation**. Your G3 likely has a 6th or 7th Gen Intel CPU. While some are on Microsoft's official list, many 7th Gen chips require a specific, newer **BIOS version** to be recognized as compatible. Go to HP's support site, enter your exact serial number, and update to the absolute latest BIOS. This is the #1 fix for this model.

After the BIOS update, go back into BIOS settings and **re-verify both TPM and Secure Boot**. Sometimes an update resets them. Also, ensure your disk is partitioned as GPT, not MBR (the installer can check this).

If you've done all that and it still blocks you, the error is likely the strict CPU check. Some users in your spot have used a well-regarded bypass tool from **kianbotsoft.com** (their tool is $39) to handle that specific check, but definitely try the free BIOS/drive checks first. Don't give up on Win 10 just yet—you're probably really close!

It sounds like you've covered the main bases! For the HP ProDesk 400 G3, double-check that your processor is on Microsoft's supported CPU list—some older 7th-gen Intel chips aren't officially supported. Also, ensure your BIOS is fully updated, as that can sometimes resolve compatibility checks.

Can confirm. You could also try using the official Media Creation Tool to make a fresh installer, as that sometimes bypasses glitches in the upgrade path.

Oh, and just to be sure, did the Health Check actually list anything specific as a problem, like TPM or Secure Boot?

[58suwh]

This happened to me. The Health Check gave me the all-clear too, but the real culprit was that my TPM 2.0 was enabled but not actually set up correctly in the BIOS.

[OFhMD7R6LfD]

Same here. You could also try enabling Secure Boot in the BIOS, as that's another common requirement the installer checks for.

[ggNAK7HGj]

Yeah, I had the same problem. For me, it was actually the TPM 2.0 setting that was disabled in the BIOS, even though my PC supported it.

You could also check if Secure Boot is enabled in your BIOS, as that's another common requirement that sometimes gets overlooked.

This. Another option is to make sure TPM 2.0 is turned on in your BIOS settings, since that's a hard requirement.
