The rest of the stuff is okay but the things to look out is for the latest MSN Messenger+ Malicious Software Removal Tool which is really very effective. Each of these patches are unistallable by a simple tool called Hotfixes Mechanic in the Autopatcher folder which can be removed in case of an instability after installation. You can add new wallpapers, themes, sort your start menu, speed up your common ms programs and also edit the module to install a program for u automatically so that you won't have to do it again & again.
However, there is one fix relating to 'Your comp. stops responding after SP installation'. This one never installs on my system & always hangs it up. So, it's always out of my selection.
Savvy!
