I will be doing a Windows 10 build soon. I have heard that Microsoft still allows you to use a Windows 7 key from an old install to get Windows 10 to activate. Now I bought an OEM version of Windows 7 Home Premium a while back and am looking to upgrade to Windows 10 Pro. If I put in my Windows 7 key will it only give me the option to go to Windows 10 Home? Or will I be able to use it to upgrade to Windows 10 Pro as well?
If it won't i'm totally fine with using a site like Kinguin.net to purchase a Windows 10 Pro key, just want to know what to expect. I already made a flash drive with Windows 10 on it.
