okay, so in the past they have been OP system disks that could only be installed once, or only on one PC ever. then they have been disks that were able to be installed on multiple machines and as many times as needed, I used to have a copy of win ME that I reinstalled on a old PC over 10 times I know ( computer keep crashing)
So, is there any copy's of windows 7 Pro out there that can be installed on multiple PC's and multiple times or what is the deal with win 7? I keep wanting to upgrade my current PC if i can or if not I want to buy another used PC i keep finding some with Duo core's and 4-6 GB of memory RAM but lots have XP on them. Is it simple enough to just buy it and then load Win 7 onto it? be nice to be able to even maybe load it onto my current Machine also. I guess it would run it ok being a single pro and 2.8ghz and 2.99 Ram can stick up to 4gb in if needed. I understand win 7 needs more ram to run well?
