Updated my parent's PC, my father's Acer centrino laptop and my mother's Acer centrino laptop to Windows SP2. Also updated Office 2003 to SP1.
Took a damn fuckin' long time to update through out WiFi network although I have to point out that this has nothing to do with WiFi. Its more to do with Telekom's retarted StreamyX connection.
So far what has happened since I updated. Nothing. My 3rd party firewall seems to be holding on just fine against any attacks. SP2's firewall is a joke and does not guard against outgoing connections. Those who think that SP2 will protect your Windows PC needs to think again.
Invest in a bloody firewall or move to Linux!!!
