Here is how to do it with a registry key.
* Go to HKEY_LOCAL_MACHINE\SYSTEM\GWE
* Create a DWORD named Animate if it does not already exist
* Edit the DWORD value named Animate
* 0 - Disables Window Animation
1 - Enables Window Animation
However, it needs restart of the device. I would like to know if there is anyway to disable it instantly, programatically ?
