Windows Vista comes with several new enhancements, however for these added features you have to pay the price of slow processing speed for even the fastest of computers. The main reason is the visual upgrades, which though looks good can drastically reduce the performance of your system.
If your system can not take the load of Window Vista and you still want to use it for considerable performance, you may tweak Windows Vista for certain optimizations. For example; when you minimize, maximize or close any windows/applications, the animation speed to perform these tasks is a default setting which is not under the control of the user.
Never the less, you can make this transition run slower while holding the SHIFT key button; after performing the following registry hack as shown below:
1. Click on the Start button and type regedit in the Start Search field, then press enter.
2. If User Account Control prompts you for consent, click on Continue.
3. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
4. In the right hand pane, right click on an empty space and from the context menu that appears choose “New > DWORD (32-bit) Value”.
5. Give the new DWORD (32-bit) Value a name of AnimationsShiftKey.
6. Double click on the “AnimationsShiftKey” value and give it a value of 1.
7. Close the Registry Editor and log off of Windows and log back in for this to take effect.
If you have successfully edited the registry, you will notice that the animation speed has become slower when compared to previous without holding the SHIFT key. Enjoy!
