lol... Microsoft really are a bunch of tossers with their BS about needing an 8th generation or later CPU and a TPM 2.0 module, UEFI firmware, secure boot, etc. for Windows 11.
I just installed Windows 11 Home on the PC I'm using right now which has an Asus H81M-PLUS motherboard which was released in 2013 (I bought it in 2015) with a 4th generation CPU and no TPM (Trusted Platform Module). The PC case is a recent purchase, about 6 months old (this setup has been in 3 different cases since 2015).
I had to create a 'special' USB installation stick with a USB creation program called Rufus which modified the install files to bypass the CPU and TPM checks, etc. and I also had to use a Command Prompt 'trick' to install 11 without an Internet connection and also without using a Microsoft account. I'll let you Google all that if you like.
Not sure why the install date says 18/4? I entered the date and time manually for Perth and I must have been a day off. The PC wasn't connected to the Internet while I had 11 running so it couldn't set the location, time and date automatically.
Had a play with it for a while and it works perfectly but I've gone back to Windows 10 (using a Macrium Reflect image backup) for now. I may install Windows 11 again at a later date and I do have another PC here which has an 11th generation CPU and TPM, etc. and I might put 11 on that later this week, it also has Windows 10 on it at the moment.
The PC with Windows 10 restored for now.
I love playing with this stuff.
