Just a observation.
In Black Viper's Windows Vista SP2 Service Configurations I disabling Virtual Disk (Tweaked).
Desktop Maestro (PC Tools) calls Vistual Disk when it runs it's Disk Management applet.
Not sure if this is help to anyone. Seems you people here at Black Viper has done much appreciated work in configuring Vista and other products and I thought I would throw in my 2 cents.
