Windows normally delays menus before they are displayed. For regular users this delay can become annoying, with this setting you to change the delay time or remove it altogether.

Open your registry and find the key below.

Create a new string value, or modify the existing value, named 'MenuShowDelay' and set it to equal the delay you would like before the menus are shown as a time in milliseconds.

Log off or restart Windows for the change to take effect.

Settings:
User Key: [HKEY_CURRENT_USER\Control Panel\Desktop]
Name: MenuShowDelay
Type: REG_SZ (String Value)
Value: 0-999 (milliseconds)
