Windows 11 requirements and older CPU's


Recommended Posts

Has anyone here installed Windows 11 on a PC using an older CPU, like a Haswell-E or Broadwell-E i7?


I've checked the full 'compatibility' list at the below URL's and was wondering if anyone else has managed to get it to install on a computer with a CPU not on the list?


My i7 5820K is not on the list of 'compatible CPU's', hence the question...


My PC didn't initially have a TPM 2.0 either, which I think is built into newer CPU's, but I resolved that by buying a cheap TPM 2.0 module for my Rampage V Extreme.



This specification details the Intel processors that can be used with Windows 11, version 22H2 customer systems that include Windows products, including custom images.

There are hacks that can do it on older cpus but I think if you have a tpm module it should work normally.

agreed, as far as I know,the main reason for the cpu compatibility was because those supported some form of encryption while older ones supposedly weren't secure enough without a tpm module. I may be wrong and MS may have been blowing smoke, but that's what I remember reading. 🙂   Edit: On a side note, watch if you DO use the tmp feature of a cpu because if you end up with bios issues later and need to clear the cmos and re-install the bios, it'll assign a NEW encryption key to the cpu and old files won't be seen anymore. Had this problem and had to turn tpm off. Now I can see all my files again but NOT upgrade to 11. 🤣 When I get ready,I'll copy what I want to save,and do a fresh install of 11.
