How to re-enable Aero if it is not working.

If for some reason, you are unable to enable or run or start Aero feature in
Vista, here are some troubleshooting steps you can try :

First, ensure that your version of Vista has Aero. Home Premium, Business &
Ultimate have Aero.

Also ensure that your Graphic card supports WDDM (Windows Display Driver
Model)

Next, right-clicking on the desktop, select Personalize.

Click on Themes and select the default Windows Vista themes.

Next, in Windows Color & Appearance, ensure that Enable Transparency is
checked.

Now, inspite of this, you still find that Aero does not work, or your Aero
has stopped working, simply copy-paste the following command in Vista Start
Menus Search Box, and hit Enter.

rundll32.exe Dwmapi.dll,DwmEnableComposition

This will re-enable Aero by flushing it. From :
