Window xp cleverly uninstalls the screen saver of the public computer

The school's computer room is shared by multiple classes. A class student specifies a screen saver and sets a password during class. The next class student is in the class if specified. The screen saver is run without using the computer for a period of time (the shortest time is 1 minute). Since the students in this class don't know the password, they have to press the Reset button to restart the computer. At this point, the hard disk of the computer is rotating at high speed. Pressing the Reset button to restart the computer will scratch the hard disk with a large amount of data. In the long run, the hard drive will be aborted, not only will lose a lot of teaching data, but also increase the financial burden of the school. Therefore, in the computer room where the school is used in multiple shifts, the screen saver for uninstalling the computer has become an urgent requirement of most teachers. Below, the author wrote down his own computer screen saver and shared it with his colleagues. First, the setting method in Windows XP (2000)
1. Open the "Run" dialog box, enter the Gpedit.msc command, open the "Group Policy" edit window. 2. In the Group Policy edit window, open Local Computer Policy→User Configuration→Administrative Templates→Control Panel→Show Branch, and then double-click the Hide Screen Saver tab on the right side of the window to open the hidden screen saver. Program tab properties, in the Properties dialog box, select Enabled and click the OK button. Second, the setting method in Windows 98 (Me) 1. Open the "Run" dialog box, enter the Regedit command, open the Registry Editor. 2. Go to the HKEY_CURREN_USER\\Software\\Microsoft \\Windows\\CurrentVersion\\Polices\\System primary key. If the System primary key does not exist, create it manually. 3. Create a new DOWRD key value of NoDispScrsavPage. A value of 1 indicates that the Screen Saver option for Display Properties is hidden, and a value of 0 indicates that the screen saver is displayed normally.
