Speed up the start menu by configuring the delay before a folder in the Start Menu is shown:

This can also be configured with the PowerToy TweakUI Win9x/WinNT4/Win2k, WinXP.

[HKEY_CURRENT_USER\ Control Panel\ desktop]
MenuShowDelay = 50 (Default 400 ms)

Configure whether to scroll the Start Menu or use multiple columns (Requires Active Desktop):

[HKEY_LOCAL_MACHINE\ Software\ Microsoft\ Windows\ CurrentVersion\ explorer \Advanced]
StartMenuScrollPrograms = “false” (Default=”true”)

Configure whether to use Personalized Menus and hide programs not often used (WinMe/2k/Xp)

Win2k: Start Menu -> Settings -> Taskbar & Start Menu -> Untick “Use Personalized Menus”

[HKEY_CURRENT_USER \Software \Microsoft \Windows \CurrentVersion \Explorer \Advanced]
IntelliMenus = “No” (“Yes”=Enabled, “No”=Disabled)
