should I keep using the Service Pack 2 or get the Service Pack 3?

if your using genuine windows xp os, it doesn't matter.. for those using pirated versions, like me, we can update from sp2 to sp3 by disc, and not by internet.. 2 times i updated via internet and after some auto-updates, my computer becomes very slow.. and later resorted to reformat & re-install the winxp.. now i never update my winxp.. i have a windows vista on another computer but i update it regularly because it's genuine.. i know microsoft will not mess with it.. hehehe...

I insist you upgrade to service pack 3,it got lots of security features that of vista like NAP,modified version of msconfig,mmc is that of vista and all bugs found in service pack 2 has been fixed in SP3, all i can say is, SP3 is nothing but package of all win xp updates provided after service pack 2 along with few Vista security updates. if you have 512 Mb ram sp3 works fine even works with 256 MB ram. it recommended you have minimum of 1Gb of free space in ur windows drive as sp3 consumes around 1 GB harddisk space(Including Backup)..

i think that u must using sp2 microsoft never released service pack 3 its some think made locally so keep sp2 and update it. its enough

Think about it...all a service pack is are a few major along with a few minor fixes to the program in which the developers put on the consumers behalf. Over time new and creative ideas come out in the open and everything associated with that idea must evolve to it. For example a new digital camera has to have a driver installed to run wouldn't it be nice if XP already had that driver for you. There is nothing wrong with the new service pack no bugs or performance guzzlers just a good ole beef up.

SP2 is the best stable one right now, upgrade to SP3 you gona just get into some troubles, some softwares won't gona work, you gona need a Everyday Updates and so on, a lot of Head-ache :)
