How to Disable AutoRun Function in Windows

The AutoRun is a feature introduced in Windows 95, along with the function AutoPlay. This was implemented in order to facilitate the installation of components or software by users without technical knowledge. But being vulnerable, deleting AutoRun is a wise decision at times.

How does AutoRun work?

AutoRun is specific for when a new storage drive is mounted on the system, whether it is an external hard drive or a USB drive, or a media disk (such as when you insert a CD or DVD into the drawer). In these cases, AutoRun scans the drive for data, and can automatically start installing files that enable the AutoPlay menu, which displays actions for the user.

Microsoft kept AutoRun up to Windows 7, shutting it down because it was easy to use to attack a computer with pendrives or CDs with viruses, thanks to its ability to install software alone.
