Hey Mike, uninstall via Impulse, reboot, run Ccleaner, cleaner and registry, reboot, reinstall via Impulse. I am running same version, all file dates are 2008, you have 3 from 2007, even a couple of the 2008 dates you have are off, looks like a bad update install.
Seems this is very difficult way for a non professional user...
I had the same problems after each of WB updates. And not only this... I was so disturbed that disabled WB in the Windows Services and don't use it nearly half of year.
Now I only download and install the updates (to not lag behind the progress

) but use the default Vista Aero Style (without any transparency) with my own Wallpapers. And may tell you that my System works quickly as a bullet! For example it shutting down in a 5-8 sec. with 65-70 running processes!
