Hello all. i've not visited this forum in awhile. Glad to be back. I am upgrading my PC. New Mobo, Proc, Memory, Power Supply. I have a registered copy of Win& Professional installed (Upgrade Addition). Will i be able to install this on my new system if i use my old XP first? Would it be more advisable to install a fresh Install of Win7...whatever flavor? Have not installed new components; waiting for replies. Thanks folks...Cheers and Beers all the way!
