I'm thinking of doing a restore on my PC using the re-installtion disc that came with it. Basically to get rid of all the rubbish, tidy things up a bit and cure a problem where it 'hangs' for a while after initial switch on. However, over the last 12 months, there have been loads of windows (xp) updates and security patches! So, surely the re-install disc will remove all the security patches and I'll have to download them all again. Wouldn't this mean I'm particularly vulnerable during this time? I have broadband and use Norton firewall and Antivirus, but these will need updating again aswell. Am I worrying unecessarily? any advice on what to do.
