Make Windows Animation In Slow Mode

Here’s a nifty little Vista hack that has absolutely no purpose except for pure entertainment and eyecandy value. It will slow down the animations that occur when windows minimize and maximize to and from the Taskbar, and you hold down the Shift key.

Launch the Registry Editor Registry Editor by typing regedit at the Start Search box or a command
prompt and then:

Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM.

Select Edit→New DWORD (32-bit) Value, and create a new DWORD called AnimationsShiftKey.

Give it a value of 1.

Close the Registry Editor.

Log off of Windows and then log back in again, or else reboot.

Hold the Shift key and minimize or maximize a window. The animation will be slowed down
considerably. To make the animation go at normal speed, let go of the shift key.
