if i go with Win7 upgrade, will i need to call up M$ every single time i need to wipe and reinstall my computer or will that key work as long as theres a previous OS on the system? ive seen tricks on doing full wipes for XP users
and the full retail version, that key can be used unlimited times but on only 1 PC at a time, correct?
i cant seem to find any of these answers online
id buy the cheaper upgrade if i can use the same upgrade key everytime i need to rewipe, BUT if i have to call M$ and get a new key every time, the $100 more pricetag for the full retail version will save lots of headaches i think
