Script to enable mouse shadow?
See the question and my original answer on StackOverflowIt's located in the famous (yet undocumented :-) "UserPreferencesMask" registry key. Here are some pointers:
A first general link with information on this key, and how the mouse shadow setting is defined: HKCU\Control Panel\Desktop\UserPreferencesMask
And a sample that explain how to code it using VBSCript (it's another key, but the principle is the same): Set UserPreferencesMask Binary Registry Key
