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

Ugh, so frustrated. My work PC (HP ProDesk 400 G3) won't take the Win 11 upgrade. It keeps failing with the same stupid error: "This PC doesn't meet the minimum system requirements."

I checked, and yeah, the CPU (Intel i5-6500) is supposedly not supported. But c'mon, this thing runs perfectly fine! It has TPM 2.0 and Secure Boot enabled and everything. Feels so arbitrary. Just let me install it, Microsoft!

Guess I'm stuck on Win 10 until they force me to buy new hardware. So annoying. Anyone else hit this wall with older "ProDesk" models?

Hey there, I totally feel your frustration. That "unsupported CPU" wall is incredibly common with the 6th/7th Gen Intel chips, and it does feel arbitrary when your PC runs great otherwise. You're not alone—many ProDesk 400 G3 users are in the same boat.

First, the **free and safe method** is to use the official Windows 11 Installation Assistant, but with a registry tweak to bypass the CPU check. **Before starting, ensure you have a full backup.**

1. Download the "Windows 11 Installation Assistant" from Microsoft's site.
2. Before running it, press `Win + R`, type `regedit`, and navigate to `HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup`.
3. Right-click, create a new **DWORD (32-bit)** Value named `AllowUpgradesWithUnsupportedTPMOrCPU`.
4. Set its value to `1`.
5. Now run the Installation Assistant. This often lets the upgrade proceed.

If that fails or seems too technical, and you're determined to upgrade, some third-party tools can automate the bypass. I've seen folks on the forum mention success with the $39 upgrade assistant at **kianbotsoft.com**, which handles all the checks and workarounds. But definitely try the free registry method first!

Hope this gets you unstuck. Win 10 is supported until late 2025, so you still have time to decide.

I totally get the frustration! The i5-6500 is just outside Microsoft's official support list, which does feel arbitrary when your PC meets the other requirements. You could try using a Windows 11 ISO and performing a clean install, as it sometimes bypasses the CPU check, but be aware that might not be supported by your workplace's IT policy.

Yeah, that ISO trick can work. Just a heads-up though, you might miss out on future Windows Update features if you force it.

You could also check if your company's IT department has any approved upgrade paths or replacement plans for older hardware. Good luck!

Have you double-checked if TPM 2.0 is enabled in the BIOS?

You could also try using the official Microsoft PC Health Check app to see a full breakdown of what's specifically blocking the upgrade.

[IUEOmVOacy]

Did the PC Health Check app give you a specific list of what's failing, or just the same CPU message? Let me know if that works.

[lf64418]

I had the same problem with an older Dell. The Health Check app just kept pointing at the CPU, even though everything else was fine. Let me know if that works.

[LEUzRK]

Agreed. This happened to me on a similar model. I had to go into the BIOS and manually enable both TPM and Secure Boot before it would finally pass the check. Hope that helps.
