Windows 11 requirements and older CPU's

[t4ct1c47]

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.

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.

Check this out.  I tested it, its missing Internet Explorer which made me have to install the full version of Windows 11, but if u have a low end old pc it's probably going to work best.
