The good the bad the ugly.
the article writer said it best ,SP3 is anticilmatic & i totally agree with that comment,& i for the life of me can't see the point of even installing it since it's nothing more than a compilation of already available updates,apart from a couple of admin features & the extra menu bit that gives a bit more detail,& what's with no IE8 for xp.
WWW LinkPS: I also have the pdf download of what the SP3 contains which is why i consider SP3 a waste of time unless your an admin,i thought it would contain some choice changes like SP2 did (

maybe if i sign the "save xp petition" it might help
