This may sound lame, but any clarification in this regard will be highly appreciated.
Has anyone actually tried re-installing win8 after formatting hard disk ?
Heard that these keys can be used to activate Windows only once, even on the same machine. That is, the keys can't be used again after formatting the hard disk even if the hardware remains the same.
I couldn't find any such statement in the EULA but since a friend (rather senior) said he used a MSDN key for Win7 and he couldn't use it after re-installing. I don't know how far that's true. So thought of asking here.
