Hey guys,
I'm new here and I'm glad to chat in Tom's hardware.
I have a 6 months-old desktop running win7 and i think to upgrade it to win8 pro as there is a discout. But the problem is that I have an old toshiba laptop under win vista and i want to upgrade it windows 7 USING THE SAME KEY AS ON MY DESKTOP (have the oem installation disc). Will it let me to activate win7 on this laptop of course after ugrading to win8 on the desktop? Also if this is possible are there going to be any driver compatibility issues on the laptop and what should I do?
Finally I'd like to hear some opinions about Win 8 - is it better than 7, any bugs, performance,etc.?

Thank you, I appreciate it. :)
