XP under the U disk Auto playback is very easy to infect the virus, if you want to disable the automatic playback of Windows XP all at once, then follow the steps below:
1, click "Start → run", in the Open box, type "Gpedit.msc", click "OK" button, open the Group Policy window;
2, in the left pane under Local Computer Policy, expand Computer configuration → administrative Templates → system, and then in the right pane under the "Settings" heading, double-click "Turn off AutoPlay";
3, click the Settings tab, select the Enabled Check button, and then in the Close AutoPlay box, click All drives, click OK, and finally close the Group Policy window.
This "Turn off AutoPlay" setting also exists in User Configuration. However, setting in Computer Configuration takes precedence over the settings in User Configuration. Note that the "Turn off AutoPlay" setting does not prevent the automatic playback of the music CD disc. To prevent the music CD from playing automatically, you only have to use the attribute Setup method.
In addition, daily use, as far as possible using the right mouse button "explorer" Open u disk, and do not double-click directly open.
