Attn Windows users: Windows XP Service Release 2 is headed your way via Automatic Updates & the Windows Update site. XP Home users should start to see it phased in today while XP Pro users should see it starting Wednesday.
Two tips: Make some backups of your My Documents and important stuff (photos, music, whatever you wouldn't care to lose). I know you do that already, but humor me. Put them on CD/DVD/Network/whatever – just not on your PC. Secondly, create a restore point now. That way if it all goes south during the upgrade you can restore your system back to it's config today.
