Disable AutoRun in Windows
Page content

AutoRun in Windows is the operating systems’ response to a change of hardware that makes the system check the medium’s root directory for the presence of a file called Autorun.inf and process its instructions such a starting an installer or a game for example. That’s why AutoRun in Windows is a latent entry point to infect Microsoft OS based computers with potentially unwanted and malicious software including viruses, Trojans, rootkits etc.

AutoRun during execution also calls a routine named AutoPlay which scans the medium discovered by AutoRun in Windows, and, depending on its content and the latter’s configuration gives the user a contextual menu with programs or actions to choose from, launches the program it had been configured to either manually or during installation of a piece of software, or takes no action at all.

Autorun and AutoPlay properties in Windows can be configured independently or in conjunction; however it is sufficient and more secure to disable AutoRun in Windows and have AutoPlay bring up a contextual menu with programs and actions to choose from.

AutoRun in Windows can be disabled for all users of XP or Vista by means of computer configuration and on an user basis in certain Vista editions like Ultimate with computer configuration always taking precedence in case settings conflict. As configuration options are identical I will show you below where to disable AutoRun in Windows Vista (Ultimate Ed.) for specific users, but then stick with computer configuration throughout the article.
