Upgrade requirements for Windows 11 processor rejected

[maddy-01]

Windows 11 says my current processor is not compatible althought it has 3.5 gigaherz and computer is 3  years old out of warranty. What do I do?

Just download the modified Windows 11 ISO with all the limitations removed and install it as usual) You can find such ISO over the internet. Windows 11 is the same Windows 10 but with a new "skin".

Hello
Warning @maddy-01 
For the moment, it is not clear enough, the user is not always aware of the consequences
We can tell you, that despite everything we can install windows 11
Only, it is not without risk ..
Microsoft, warns users, but it's not very explicit

Windows 11 on devices that don't meet minimum system requirements 
We risk having serious problems, probably updates, security problems, we do not really know what else

If the installation goes well for some, for others it can be complicated
Hp also might not provide any update:

HP PCs – Support for Windows 11 | HP® Customer Support

Think carefully, before taking the risk, see the experiences of other users, see if it can be interesting, or if you can wait to have a new computer later, 100% compatible!
Windows 10 remains one of the best systems, and can be used for quite a while.
