A big security problem now days is the autorun for removable devices, that can breech the security of your IT system.

Ok, so how do we disable this autorun ?
This applies to Windows 7, but you can also use it in Windows 2008 ( for a domain GPO ).

1. Go to Start / type: gpedit.msc / double click on gpedit.msc 

2. In the logal GPO Editor Expand Administrative Templates / Windows Components / Click on Autoplay Policies / Double click on Turn off Autoplay:

3. Check the Enabled radio button / and select All drives ( or only the drives that you want to disable, depending of your scenario ). Then click OK:

ENJOY.
