all right, i’d never buy vista ultimate or home premium or even home basic edition, since they are very expensive here in my country (not like the US) they cost here thousands of my local money, so i’d just activate it every month with slmgr then after three months (no copy lasts more than this with me) i install a fresh version, again and again.
thanks microsoft for making this legal, lol.. as with XP i had to use an oem pirated version

True that…and you could even go as much as a year using that Vista trick if you modify that one registry setting. And I can’t remember the last time that I went a year without reinstalling Windows.
