The autorun CD is usually turned off for security reasons – in this case, there is no threat of automatic download of malicious software. However, on disks with the programs, especially the license, automatically download the virus and Trojans are rare. So disabling AutoPlay gives the user quite a few advantages, but brings a lot of trouble.
To enable auto-start, you must start the appropriate service. If you are running Windows XP, open "start" - "control Panel" - "administrative tools" - "Services". Locate the service "shell hardware detection" and double click it with the mouse. In the opened window, select the startup type is "automatic". Start the service by pressing the "start" button. Insert the CD, it should start automatically.
If you are using Windows 7, open the "start" - "control Panel" - "System and security" - "administrative tools" - "Services". The service itself runs exactly the same as in Windows XP.
You can configure the behavior of the drive when you insert a CD with certain files. To do this, open "My computer", click your right mouse button and select in the context menu item "Properties". In the opened window select the tab "AutoPlay". Next, select the file type and assign the desired action of the drive. Confirm the change by pressing "Apply". After that, configure the following type of file etc.
In that case, if for some reason enable auto-start fails, check in the registry a responsible option. To do this, start the registry editor: start - Run, type regedit, and press Enter. Next, open the registry: HKEY_LOCAL_MACHINESystemCurrentControlsetservicescdrom and select the folder CDRom. In the right part of the window, view the value of the parameter Autorun, it should be equal to 1. If it is 0, click parameters, right-click, select "Modify". Enter in the Value field 1.
If the value is already equal to 1, you should see the string registry HKEY_CURRENT_USERSoftwareMicrosoftwindowscurrentversionpoliciesexplorer. Scroll to the folder Explorer and look at the value of the NoDriveTypeAutoRun registry entry, it should be equal to 91. If there is more, click parameters, right-click, select "Modify" and type 91 in the Value data field.
