Im in the process of installing Windows 8.0 Pro and 8.1 Pro on a New build Ive done for my brother so what I have is a copy I won a while back of Windows 8 Pro Full version with legit product key! ,and also Just finally DL Windows Windows 8.1 Pro Full package version from Microsoft build 9600! To test it out Ive done a Fresh install of Windows 8 Pro on a spare PC with no internet connection and did not activate Windows 8 Product key for test reasons! Install went perfectly! No Issues! Then I proceeded to install 8.1 Pro using the upgrade option for saving files and personal settings from Windows 8! The 8.1 Upgrade went perfectly and created its own product key and Product ID! My Question should I activate it using the product key from Windows 8.1 Pro or should I activate it using product key from 8.0 !
Another Question When I install Windows 8 pro on the New build PC should I activate it prior to installing Windows 8.1 Pro and then do the upgrade? Or should I upgrade it to 8.1 and use the product key it generates or change it to the Wondows 8 Pro key and then Activate it? Will this procedure work! ! Im not a tech genuis and also after 2 brain surgeries if diminished my ability to eplain things at times so I hope you can understand my procedure and questions!
If I do install Windows 8 Pro with its key and activate it will it interfere with me using the same key to activate 8.1? Hope you can make sence of my questions!
