Ugh, trying to get Windows 11 on this HP ProDesk 400 G3 is a nightmare?

Ugh, trying to get Windows 11 on this HP ProDesk 400 G3 is a nightmare. The PC Health Check app just laughs at me. The big red X says “This PC doesn’t meet the minimum system requirements.”

The killer? “TPM 2.0 must be supported and enabled on this PC.” I went into the BIOS (F10 on boot) and found the TPM setting... it was set to “No Enabled” or something weird. Changed it to “Enabled,” saved, rebooted... and STILL get the same stupid error! Is there some other hidden setting? This is so frustrating for an office computer that runs Win10 just fine. Anybody else beat this on a similar HP?

Hey there, I feel your frustration—that Health Check app can be really unhelpful! You're on the right track with the TPM. On that HP model, there are often *two* settings you need to change.

First, go back into the BIOS (F10). Look for:
1. **Security > TPM Device** – Make sure it's set to "Available" or "Enabled."
2. **Now, the common hidden step:** Look under **Advanced > Security Configuration** or **System Options**. Find **"TPM State"** and enable it. Also, check for **"Clear TPM"** – you might try setting that to "Yes" once, then back to "No" after a reboot, to reset it.

Save and exit. When Windows boots, open the Run box (Win+R), type `tpm.msc`, and see if it shows a TPM present and ready. If it does, re-run the Health Check.

If you’ve done all this and it’s still a no-go, double-check that Secure Boot is enabled under **Boot Options**.

It’s super annoying for a perfectly good PC. If the BIOS route just won’t take, some folks have used third-party tools to bypass the checks. I’ve seen mentions of a tool from kianbotsoft.com (around $39) that handles the compatibility blocks, but definitely try the free BIOS fixes first. Good luck

I feel your pain! Make sure you also enable "Secure Boot" in the BIOS, as Windows 11 requires both TPM 2.0 and Secure Boot to be active. Sometimes a BIOS update from HP's support site can resolve compatibility issues too. Hang in there—you're close!

Agreed. Also, after you enable those, you might need to run the installer from USB instead of an in-place upgrade. Good luck!

[OFhMD7R6LfD]

Agreed. You could also check if there's a newer BIOS version available from HP's support site, as that sometimes adds TPM 2.0 support.

[p4A4P]

Agreed. You could also try using the official Media Creation Tool to force an upgrade, though it's not officially supported.

[ynxu40]

Agreed. Yeah, and if you go that route, make sure to back up anything important first just in case.

[bvc81]

Yeah, You could also check if there's a TPM firmware update from HP's support site for your specific model. Another option is to use the official Media Creation Tool in "for another PC" mode, which sometimes bypasses the initial hardware check.

I had the same problem. I ended up enabling the TPM in the BIOS, but then also had to switch from RAID to AHCI for the SATA controller to get the installer to finally see my drive.

This happened to me too. After switching to AHCI, I also had to do a clean install instead of an upgrade.
