Start menu is slow in responding?
Want to boost response time of start menu ?
If your hardware configuration (read CPU,RAM) is not upto speed but still want to boost response time of start menu, here are a few tricks that might help.

Open registry editor by going to START-RUN and entering regedit and navigate HKEY_CURRENT_USER \ Control Panel \ Desktop \ MenuShowDelay to key. Change the value (default may be 400) to 5 or 50 or even 0. This should speed up, If you are not all that crazy for shadowy effects, you can further speed the things up by going to DISPLAY Properties Window and from there to appearance and over there clicking Advanced command button and check off Show menu shadow.
