Issues with windows 11 after upgrading

[Run4taco]

I have a hp prodesk 600 g1 small form , I have added 2td hard drive and 32gb of ddr3 memory , and I’m trying to load windows 11 and it keeps telling me my system doesn’t have the minimum requirement for windows 11. What am I missing?

Hi Run4taco

The issue you are running into is a very common problem with older PCs trying to upgrade to the latest operating system.

You have correctly upgraded the most important capacity requirements (RAM to 32\GB and adding a 2tb hard drive), but the HP ProDesk 600 G1 SFF fails to meet two critical, non-negotiable hardware requirements that Microsoft enforces for Windows 11:

1. Unsupported Processor

• The HP ProDesk 600 G1 SFF uses 4th Generation Intel Core processors (e.g., Core i5-4570 or i7-4770).

• Microsoft officially requires an 8th Generation Intel Core processor or newer (or AMD Ryzen 2000 or newer) for Windows 11 installation.

2. Incompatible Trusted Platform Module (TPM)

• The ProDesk 600 G1 has a TPM 1.2 security chip.

• Windows 11 officially requires TPM 2.0. There is no way to update the physical TPM 1.2 chip to 2.0 on this model.

In summary, your RAM and storage upgrades are great, but the block is due to the old CPU generation (4th Gen) and the TPM 1.2 chip.

I hope the above is helpful

If you are running W10 on your PC, you can upgrade it to W11 but you will have to use a workaround that bypasses the W11 hardware checks so you can do that.

Watch this video for an easy way to do an in-place upgrade from W10>W11.

How to Install Windows 11 25H2 on Unsupported PCs (New Easiest Method)

I'm running W11 on all of my PC's that don't meet Microsoft's minimum W11 hardware requirements and they all work fine.

Two of those PCs are my Dell Optiplex PC's that use the same Intel 4th gen processors as the 600 G1.
