Hi,

 Thanks for the reply about my HP OMEN. So, can I upgrade my motherboard to accept the AMD Ryzen 9 5900 for Windows 11 upgrade? Or, do I need a new PC?

You're very welcome.

There aren't any motherboards that would work in your PC to support W11 or the AMD Ryzen 9 5900 processor.

You can install W11 on your PC without spending a dime.

If you are happy with your PC, and if you are interested in doing an in-place upgrade from W10 to W11 24H2 on your PC as is, watch this video, which is the easiest way to do it in my opinion, and I have used several different ways to do this during the last 3 years.

Download the W24H2 ISO file and use that (3rd option).

Download Windows 11

You can download the free 7-Zip file utility from the link below. The top line is for 64 bit.

You'll have to repeat this procedure if and when Microsoft rolls out the new W11 builds because a PC that does not meet Microsoft's minimum W11 hardware requirements will never automatically get the update to the next build.

They have been releasing new W11 builds each October so far.

Other than that, your PC will continue to get the monthly cumulative and other updates.

That's only a minor inconvenience to have continued OS support beyond October of 2025.

If things don't work right on W11, you have 10 days to easily go back to W10 as long as you don't delete the W1 upgrade files or the Windows.old folder.
