upgrade my Desktop PC

[Author1947]

My HP system is only 3 years and 6 months old. In like new condition, how can I upgrade to WIN11? It seems that since it came out nothing is working well in my current system when I went out of warranty they changed all the Properties on all category's to GENERIC (no changes can be made) WHY?

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.

I have performed the installation with a compatible computer ..
And I can not take full advantage of the more or less interesting features, because you have to have a certain material
https://www.microsoft.com/en-us/windows/windows-11-specifications
So far, so there is nothing extraordinary about this system
So if the computer is not compatible, you have little interest in using it ..
In some cases, we can have more problem than something else (performance etc), it is better to wait until most of the bugs are solved.
And even better to have a 100% compatible computer, in order to be able to take advantage of the available features
Now, if you want to give it a try, first plan to use specialized software, and make a ghost copy of your installation.

You will not be able to install a compatible processor
you would have to force install windows 11
there are several tutorials on the net, it's up to you

be a little more specific, what are the problems exactly
Nothing says that upgrading to windows 11 will fix this!
