Windows 10: How to upgrade WIN8 system to WIN11

Hello, I bought a WIN8 system and installed it on a laptop, and later upgraded to WIN10. Since this computer is relatively old, I have now bought a new desktop computer. Can I use this system code to install it on the new desktop computer? Do I need to go through any procedures to upgrade to WIN11? Thank you!

Upgrade from Win11 Home to Win11 Pro with a unused Win8 Pro Key?

As the subject says. I found two old Win 8 Pro keys that I never got around to use (actually one is on a physical Win8 DVD and the other is a Win 8 Pro key I bought online back when Win8 was launched).

I was wondering if I could use one of these Win8 Pro Keys (the digital one looks a better choice, since my laptop doesn't have a DVD reader) to upgrade my current Win11 Home install to Win11 Pro.

Thanks for your assistance.

 

Upgrade from Win11 Home to Win11 Pro with a unused Win8 Pro Key?

Follow up: I tried to change the product key to the generic Win 11 product key VK7JG-NPHTM-C97JM-9MPGT-3V66T, which in theory should give me a unactivated Win 11 Pro, on which I could try the Win8 Pro product key (or even a Win 11 Pro Key from the MS Store). However the upgrade procedure immediately stops and tell me I don't have a valid product key.

Same thing happens if I just enter the Win8 Pro key. Apparently my Win 11 Home doesn't feel like being upgraded and that's it. I still can't help wondering what's exactly the point of the generic key though.

At least the system seems to be intact and the original OEM Win11 Home key is still in place, so I didn't have to restore anything.

 

Upgrade from Win11 Home to Win11 Pro with a unused Win8 Pro Key?

Hi. thanks for your quick answer!

Sorry for not having been clear enough. I don't need to upgrade my copy of Windows from Win8 to Win11, because I already have Win11 up, running and activated (the laptop originally came with Win10 and updated to Win11 without issues).

What I would like to do instead is to upgrade my current copy of Windows from Win 11 Home to Win 11 Pro using the Win 8 Pro key I bought in 2013.

PS In the mean time I found a post here on how to do the same thing with Windows 10, hopefully it also applies to Win11 but I'd still run a sanity check before breaking anything, including the EULA
