If I,m not mistaken, when SP2 is installed it automatically adds to the startup 1) Seurity Center, 2) Windows Firewall configuration, 3) Automatic Updates setup, 4) Windows firewall configuration, 5) Wireless networking setup options. None of these need to launch at setup, especially if you have told Windows what you want to use & what not; plus, access to them is available through the Control Panel at anytime if you want to make changes. I would remove them from startup & expect to see a faster boot. Also, try running HijackThis! program to see what Code 04 startup entries are added (most are in the registry & thus won't show up in the startup folder); you can disable any you don't want.
