Speed up the Start Menu

You can easily change the speed of your Start Menu by editing a Registry Key. Fire up the Registry Editor by typing "regedit" at the Run command in the start menu and navigate to the following key:

HKEY_CURRENT_USER \ Control Panel \ Desktop \ MenuShowDelay

By default, the value is 400. Change this to a smaller value, such as 0, to speed it up.

If this doesn't work for some reason, then you might try the following: Navigate to Display Properties then Appearance then Effects and turn off the option titled Show menu shadow. You will get much better overall performance.
