Have you found it annoying that when you insert a CD Windows open Internet Explorer and a list of options just windows-vistapops up when it autoruns? Would you rather prefer that Windows lets you browse the CD anyway and let you reach to directly what you need? Here is a registry hack which is used to disable autorun on Windows XP and Vista.

Editing registry values is not a task you would want to do without any prior knowledge or guidance. If you alter any other values by mistake, it might lead to catastrophic situations. It is better to back up your registry.

You can disable AutoRun through Group Policy, but this method doesn’t work on Windows Vista Home or XP Home. So registry editing option is the easiest means.

Lets now come to the registry tweaking part,

1. Go to ‘run’ and type ‘regedit’ to open the registry editor.

2. Navigate to the key :

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer.

3. Create a DWORD (32-bit) value named NoDriveTypeAutoRun., if it doesn’t already exist.

3

4. Right click on the new value and click modify.Set the hexadecimal value to 000000FF(the decimal equivalent of 255). Now you can type all preceding zeros, or you can just type FF.

This will disable AutoRun on all types of drives, but you can be a bit more selective in which drives you choose. There are several options in which you can type in specific values to disable autorun only on specific drives.
