None of the processors meet Microsoft's minimum W11 hardware requirements if that is your objective.

If you want to install W11, you can do an in-place upgrade from W10>W11 by watching the video at the link below:

This is the method I have used to upgrade unsupported PCs to W11:

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

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 or a similar procedure each October when Microsoft rolls out the new builds because a PC that does not meet Microsoft's minimum W11 hardware requirements will never automatically get the update to the next build.

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.
