I have held off (head buried in sand!) installing SP3 on this PC (See title - XP Professional) for quite a while ( :-) ) .
Last time I reviewed it I didn't go ahead because I was concerned after looking at various web information about the availability of drivers (given it's age).
Microsoft are withdrawing security support from next March and I am concerned that without SP3 the PC isn't as secure as it might be.
Do I need to go ahead with SP3 - I mean everything is working fine at the moment (as far as I can tell!), and, I only use it for back up, occasional website updates (it runs Macromedia Dreamweaver MX 2004) and a graphic package. Both of which won't run (reliably run) in Windows 7. But I do need the machine for these.
Am I ok with SP2 or is there a good reason to install SP3 (any other updates are all up-to-date via the MS Update downloads).
