I need to update TPM 1.2 to 2.0 so I can get windows 11 on my desktop computer Model XL506AV

Your PC does not meet Micrsoft's minimum hardware requirements beyond not having a TPM 2.0 security device (and you cannot upgrade the TPM 1.2 firmware to 2.0 because your PC is way too old).

The processor is not supported.  Needs to be an Intel 8th generation core or newer, and your PC's motherboard only supports the Intel 2nd gen core processors.

Also, your PC does not support secure boot.

W11 24H2 is running just fine on my HP 6200 Pro MT.

If you are happy with your PC, and if you are interested in installing W11 24H2 on your PC as is, watch this video, which is the easiest way to do it in my opinion, and I have tried many different ways to do this during the last 3 years.

Download the W24H2 ISO file and use that (3rd option).

Download Windows 11

You can download the free 7-Zip file utility from the link below. The top line is for 64 bit.

You'll have to repeat this procedure each October when Microsoft rolls out the new builds because a PC that does not meet Microsoft's minimum W11 hardware requirements will never automatically get the update to the next build.

Other than that, your PC will continue to get the monthly cumulative and other updates.

That's only a minor inconvenience to have continued OS support beyond October of 2025.
