A good tip from Husein Choroomi:
I never liked the annoying Dynamic help window in the VS.NET (Appears by pressing F1), I always disable all of the categories and topic types in the Options to increase the speed, and undock the Dynamic help window to make it nearly invisible! (The help is set to external).
Anyway, today I found a nice way to disable dynamic help completely, for doing so go to:
HKEY_CURRENT_USER\Software\Microsoft\Visual Studio\7.0\Dynamic Help
And modify the value of the Never Show DH on F1 to YES.
