Windows 10: Windows 10 Pro on an old PC / Windows 11 Pro on a new PC.

I have a previous install media retail, USB of Windows 10 Pro that I have been using for years now that I want to install on a newly built PC to upgrade to Windows 11 Pro since it meets the requirements. I would really like to keep my Windows 10 Pro PC as a backup for other tasks and the new PC as my main gaming rig. Can I install the same media with the original key and keep both installations without issue?

:)

 

will windows activate if my old pc has windows 10 pro activate will it activate on a new windows 11 pro pc?

My old dell desktop pc is windows 10 pro and it is activated it is a retail version. I ordered a new gaming pc and it comes with windows 11 pro but unactivated if I log in to my new gaming pc with my old windows 10 pro Microsoft account, will it have my new gaming pc already activated even if i log into my new gaming pc with an microsoft account already linked to windows 10 pro.

Windows 10 Pro on old PC that failed and new PC purchased and activated by shop but it is Windows 11 Home, not Pro. How do I change it to Pro?

My old PC was Windows 10 Pro, and failed. I purchased my new PC and the shop was able to activate Windows 11 using a digital license linked to my Microsoft account but it did not activate as Windows 11 Pro, only Windows 11 Home. How do I get it to change to Windows 11 Pro.

My old device is still registered in my Microsoft account and I also need to remove it.
