Sorry but a lot of issues relating to post SP2 installs are a lot to do with people tweaking their systems and the use of skinning techniques etc. On a clean install I've had no problems with SP2 and the second pc here is running well to and that was a dirty install.
So far 1000's of people have downloaded the final version of the SP2 pack, you will see horror stories about unstable systems etc no matter how well the Microsoft coders do. No two PCs react exactly the same to given situations, SP2 for the vast majority of people is a much needed installation as a lot of users of Windows and the internet out there have yet to realise the importance of a firewall when they are online
