Turn off windows 7 system and insert mobile device to play automatically

        When charging the mobile phone with a computer, after the data cable is plugged into the USB interface, an automatic playback window will pop up. This function was originally designed to make it easy to open a USB flash drive or play a CD after connecting an external device such as a USB flash drive or a CD. However, after the mobile phone is connected to the computer, the system usually recognizes the memory card of the mobile phone as a USB flash drive. This window pops up. If you just want to charge your phone, don't want to pop up this prompt every time, you can turn it off by setting it.

First, open the Control Panel in Win7, enter the "Hardware and Sound" category.

in the "Hardware and Sound" category you can see the "Auto Play" option, and click to open the AutoPlay settings.

auto-play if you want the rear part of the device connected to the computer, where provided may be a separate operation after the computer is connected to different devices.

If you do not want to allow any device to automatically play, it canceled the top "for all media and devices using auto play" before the check mark, then click on the "Save" button, and then later have the computer equipment via a data line When connected, the autoplay window will no longer pop up.

Tip:

Perhaps users have found that, in the absence of prohibited AutoPlay, sometimes the U disk into the computer nor the AutoPlay window pops up, this is why? Don't doubt that your U disk has a problem, and don't think that the system does not know your U disk. The problem is that Win7 only recognizes some empty USB devices by default and finds that there is no U disk. When you can play a file, it will not run autoplay.
