Query: Nothing like it used to be ....

I have used System Works on my computer since 2000. The 2007 version is nowhere as good as the older ones. They have deleted many of the "real" diagnostic features (Registry Optomizer), dummed down the rest, and added (rather forced) an auto-load Norton Protection Center that takes over the Windows Security Center and cannot be easily unloaded. Software should be made to be user-friendly ... this version is nothing like the previous ones!
