XP Service Pack 3

[Mysteryman]

Used every version of Windows since Windows 95 - which was useless at launch.

Only Windows 98SE can be truly said to have operated as a well behaved, balanced OS - and that only started to be trustworthy after a heavy rework from the original 98 plus a few later tweaks.

2000 and ME were utter rubbish, XP may yet equal 98SE but still has bugs and Vista, whilst I've had no probs, has not been well received.

I did with no ill effects

Just goes to show all updates have different affects on PCs
Pretty much down to what software your running I think
