The dialog box that is shown when you insert a USB stick in a computer is called the AutoPlay dialog box. This dialog box is also shown when you insert a CD/DVD with no Autorun.inf file in a computers disc drive.
With a CD and DVD this dialog box can be suppressed if an Autorun.inf is placed on the disc. Unfortunately this is not possible, by default, with a USB flash drive. In Windows 7 this is not possible at all.
In Windows XP and Windows Vista it is possible for the user to change the behavior of a USB flash drive by changing settings in Windows, and there exists also programs that can do this automatically. By changing some settings the user can make Windows to run the Autorun.inf file instead of showing the AutoPlay dialog box for USB flash drives. But for security reasons it is not recommended that a Windows user do this. And in Windows 7, with its tightened security, this possibility is completely removed.
