can you use windows 8 key for 8.1
The problem is that Windows 8.1 product keys are different from Windows 8 product keys. You canât enter a Windows 8 product key into the Windows 8.1 installer, just as you canât enter a Windows 7 product key into the Windows 8 installer.You also canât install the original version of Windows 8 with a Windows 8.1 product key.This normally makes sense, but Windows 8.1 isnât really a different version of Windows. Itâs a free upgrade to every single Windows 8 user, so thereâs absolutely no reason to introduce a new product key system.ou also canât install the original version of Windows 8 with a Windows 8.1 product key.
