Windows 7 engineering team on the U disk function automatically made two important changes

U disk is no doubt today's most widely used portable storage devices, but unfortunately, become a breeding ground for the spread of the virus, especially in auto run feature will be caught people a little attention, such as the recent outbreak of Conficker worm.

 

To do this, Windows 7 engineering team on the U disk function automatically made two important changes:

 

1, Auto Play (AutoPlay) no longer support the non-optical portable media automatically (AutoRun) function. In other words, CD / DVD / BD drive can still play automatically, but the U disk to die, into the system to run automatically after the options are not displayed, so that even if the U disk infected with a virus can not trick the user to implement and spread.

 

2, if the auto-run programs from external media (local disk), the dialog box will give tips.

 

Another point should be noted, however, is that some smart U disk will appear as its own CD / DVD drive, rather than a removable disk, Windows 7 can not do anything this time, because the device type is identified in the hardware layer.

 

These changes have been implemented in Windows 7 RC, but not a new system patents, Windows Vista / XP will also receive similar upgrades in the future.
