One shield of the school computer room, I have 35 microcomputers, Celeron 466, memory 32M, hard drive 5.1g, no soft driver, operating system: Win98, install software office2000 and other teaching software. During teaching, due to students' curiosity and misuse, they often replace the desktop unrecognizable, or accidentally deleted documents, so that the maintenance of the machine room is very troublesome, I demolished, dismantled, dismantled, put, install, installed ... non-stop Ground reloading system, busy unknown. Some people say that the registry can lock the desktop, but I tried, the effect is not good, when I am busy, she is coming, she is pc security (tm) for Windows V4.3. Since she has her, the bright sunshine, the fresh air is back, and her little exquisite is only 590K. Below I will talk about how to use her shield is to protect the school room. After installing the software and the Chinese patch (313K), restart her will quietly quietly in memory, and in addition to the anti-installation, she will always be around you. Every time she is running, they must enter the password to prevent illegal use of the software (first protect you in, password can be changed by yourself). After entering the software interface, it is similar to the general software interface, Chinese display, very good. First, fully control the computer. Click the "Computer" icon in the toolbar (WIN computer icon). 1. Click Set Browser Lock Item, select Disable Display Control Panel, prohibit changing wallpaper (isn't it to disable the display panel? Why should you change the wallpaper, this item does not care for the wallpaper, the desktop is 5 seconds Restore). Thus, students can't change the wallpaper at will. 2. Click Set System Lock Item, select the drive you want to hide in "Drive that allows access in my computer" to make students can't see the drive with a general method. 3. Click the other settings to select the lock control panel. Make students unable to change items in the control panel, two, fully control folders. Click the Folder icon in the toolbar (Win folder icon). 1. "Desktop" in the option, after selecting the lock mode, then click the Lock, lock the folder, so that students are not good to set up shortcuts or delete icons on the desktop. 2. Select other folders to be protected, but don't choose the Windows folder, otherwise the system will want you to reload the system. Third, the input password error error has automatically exited the software several times, lock the system, locking a program, etc., trying to see the hand, steal fun. After getting it, a few masters in the student silly eyes, nothing, it is really easy to use, it is also useful, it is a strong shield. With her, I will not bother it again ... so many microcomputer teachers in the country, I don't dare to enjoy it!
