How is it worth the upgrade?

No idea. Found out the key is for Windows 10 Pro. So this computer will be Windows 10 Pro. Updated.

SSD is super fast for bootup, patches installations, etc. 

Windows 8.1 to Windows 10 upgrade is no longer easy. Luckily I download the whole installation files previously. Had tried from USB boot but it doesn't work.

You can't update straight from Windows 8.1 to Windows 11. Need to install Windows 10 and then Windows 11.

Searching for that Windows 11 Pro key.
