disable Autorun registry key

With significant rise of malwares employing autorun.inf to execute and spread, Microsoft pushed a solution by disabling autorun registry key through Windows Update and Automatic update.  Please refer all the details from this url:  http://support.microsoft.com/kb/967715

Here’s an instruction to do it manually.

How to selectively disable specific Autorun features

To selectively disable specific Autorun features, you must modify the NoDriveTypeAutoRun value under the following registry key subkey:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\
Autorun is also known as AutoPlay. The following table shows the settings for the NoDriveTypeAutoRun registry value.

Value Meaning
0×1 Disables AutoPlay on drives of unknown type
0×4 Disables AutoPlay on removable drives
0×8 Disables AutoPlay on fixed drives
0×10 Disables AutoPlay on network drives
0×20 Disables AutoPlay on CD-ROM drives
0×40 Disables AutoPlay on RAM disks
0×80 Disables AutoPlay on drives of unknown type
0xFF Disables AutoPlay on all kinds of drives

Personally, I prefer 0xFF value which disables autoplay on all kinds of drives. The draw back here is when you are installing from CD ‘coz you have to manually execute the setup instead of automatically running it. The good thing, you’ll be safe from autorun malwares!

Autorun.inf
