Just thought that the RTM keys are valid for a short period. I know that RTM is the final.
And yes, I have to change the key. Because this one I have is not for production :) (MSDN)
Hello
I want to install windows 8 RTM on my pc. And after the release of windows 8 I just want to change the key to the (original/final) without new installation of the OS.
Is it possible??? Or do I have to install the OS again?
