If for some reason you are still running all the animations on Vista (you probably are running a powerful PC), then here is a registry tweak you can perform that will enable you to slow the animations down when you want to;

- Remember to backup your registry before performing any edits!

  • Open regedit
  • Go to this location
    • HKEY_CURRENT_USER/Software/Microsoft/Windows/DWM
  • Create a new key
    • AnimationsShiftKey
  • Set the value data of the key to 1
  • Done, now reboot your computer

You will now notice that whenever you press your shift key before an animation starts on Vista it will slow down.
