My old laptop running vista home premium recently expired after i "adjusted" some things inside.. I have my old original vista disks still, and obtained my product key from my hard drive using magic jellybean finder.(as i stupidly binned my laptop, prod sticker and all.) I ordered myself a nice new gaming pc which is due this friday, hoping to install my old vista upon it and save a few sheckles. However after trawling the net and reading the fine " which vista for you" post on these very pages im stumped. I presume i have the OEM version since it was bundled with my late laptop. My questions... Can i install this on my new pc in any way? I understand this version only works on one machine, but microsoft activation centre make exeptions? Can i ring them for a "new" key of some sort? Is it one machine at a time? Any tips or clarification would be most appreciated. Thanks in advance.
