hi

sorry if this has been asked before, but here goes... i have a laptop with windows vista premium 32bit , i would like to upgrade to windows 7 but im unsure what version and if i should upgrade or get the full clean install version?

i think i would be best off with windows 7 premium but should i just get the upgrade disc also 32bit or 64bit?


thanks
