Windows 7 does not autoplay CDs and DVDs

When inserting an audio, film, or software disk in windows 7 it no longer autoplays as before .
This is usually caused by a service that is not starting automatically, to resolve this do the following steps:

Click on Start then type services in the search box and select it when it is shown.
When the services window opens scroll down until you find Shell Hardware Detection double click it and change it's start-up to Automatic , click OK and then close the services window and restart windows.


Autoplay should now work.
