Fix jerky DWM animations on some NVIDIA cards

One thing we’ve noticed in Windows 7 when using NVIDIA graphics cards is that the animations for the Desktop Window Manager are not smooth. One reason for this could be that DWM now turns off transparency and blurring when rendering effects (as well as for Flip3D).

To work around this so that you experience is a bit smoother, turn off the animations:
1. Click on the Start button, right click on Computer, and click on Properties.
2. Click on Advanced System Settings in the task pane and accept any UAC prompts that may appear.
3. Under Performance, click on Settings.
4. Uncheck “Animate windows when minimizing and maximizing”.
5. Click on OK.
