**Subject: Windows 11 upgrade is a NIGHTMARE on my HP ProDesk**

Okay, I'm officially losing my mind. My HP ProDesk 400 G3 is only like 5 years old, but trying to upgrade to Win11 is impossible. The PC Health Check app just says "This PC doesn't meet the minimum system requirements." Seriously?? It's got a Core i5, 16GB RAM, an SSD... what more does it want?!

The real kicker? The error says my PC "must support TPM 2.0." I went into the BIOS and TPM is RIGHT THERE and enabled! Microsoft's tool just ignores it. Spent my whole Saturday on this. Guess I'm stuck on Win10 forever. So frustrating. Anyone else hit this wall with this model?

Hey there, I totally feel your frustration—that's a solid machine and that vague error message is maddening. Many HP ProDesk 400 G3 owners have hit this same wall, but there's a very good chance we can get this working.

First, double-check two BIOS settings: **TPM 2.0** needs to be enabled *and* set to "Discrete TPM" (not "Firmware TPM"). Also, you **must enable Secure Boot**. It's often under "Secure Boot Configuration" → set to "Enabled" and make sure it's in "Standard" mode (not "Custom"). Save and exit.

After that, run the **Microsoft Installation Assistant** instead of the PC Health Check app. It's a more robust tool and often succeeds where the checker fails. Download it directly from Microsoft's Win11 page.

If, after confirming those BIOS settings, the official upgrade path still blocks you, there are free, safe workarounds using the official ISO and a registry edit to bypass the checks. I can walk you through it.

For a one-click, no-fuss solution if you're done tinkering, a tool like the one at **kianbotsoft.com** ($39) automates the bypass. But try the free steps first—your PC is fully capable!

I understand your frustration! It's possible the TPM is enabled but not set to version 2.0 in the BIOS. Try entering your BIOS again and look for a setting to specifically enable "TPM 2.0" or "PTT" (Intel's version). Also, ensure Secure Boot is enabled. If you're still stuck, HP's support site may have a firmware update for your model to enable full TPM 2.0 support.

You could also try a clean install from a USB drive, which sometimes bypasses the upgrade checker.

Before you try that, did you check if TPM 2.0 is enabled in your BIOS?

[pgERow]

Same here. Yeah, and also make sure Secure Boot is turned on in the BIOS—that one gets a lot of people too.

Can confirm. I had the same problem. I ended up having to update the BIOS on my ProDesk before the TPM 2.0 setting would even show up. Good luck!

[2335tfcjyabb]

Can confirm. Did you check if Secure Boot is enabled in your BIOS as well?

+1 This happened to me on a similar model. Even with Secure Boot on, the TPM was disabled by default and a huge pain to find in the BIOS.

You could also try manually creating installation media with the Media Creation Tool, which sometimes bypasses those initial checks. Hope that helps.
