i cant update windows xp to sp2 because it says my version isnt legal or something along those lines (i got this computer from someone else). now im thinking of what my options are. i happen to ahve a version of win xp professioanl. is that similar to the alternative whatever thats called (home version maybe)? i ask because my computer is a P3-550 and 5 years old. its been running xp OK all this time, will it be able to handle xp pro? please do let me know
ps: if i buy xp do i have to reinstall in order to be able to update, or can i just take its serial and insert it somewhere into the windows i already ahve installed?
