Teach you how to set up three tricks to make your computer useless

Many families purchase computers, but they are afraid that their children will indulge in computers. In fact, you can find a balance between indulgence and restriction by adding flexible limits to your computer.
A command to limit the time used
The simplest method is to limit the time used. Many friends don't know it. In fact, only one command can be done.
Click Start → run and enter net user boy 123/Add/times: SA-SU,-so that a user account named boy is added to the system, his permitted logon time ranges from to every Saturday and Sunday ~ .
If you log on to the system on Monday for a limited period of time, you will be rejected. In the future, you will use this account as your child's dedicated account. Enter "Net user boy" in the command prompt to view the details of the Account Logon period (figure 1 ).

Figure 1 account logon time limit: "discard" camera
In order to facilitate contact with old students, a friend bought a camera. However, he did not want the child to use the camera to chat with strangers, so he used the "hardware configuration file" to discard the camera.
Click "Start> Run" and enter "Net user ABC 123456/Add" to create a restricted user named ABC as a dedicated account for the child.
Log on as a system administrator, right-click "my computer" on the desktop, select "properties", click the "hardware" tab, and select "hardware configuration file ", in the displayed window, select "copy ".
Enter profile 2 in the text box after "from profile 1 to:" to create a hardware configuration file named profile 2. Click OK to return to the configuration window, and set the waiting time for the user to select the configuration file to 1 second (figure 2 ).

Figure 2 use the configuration file to restrict hardware functions
Click Start> Run, enter compmgmt. MSC to open computer management, and click Device Manager to expand image processing devices ". Open the camera Properties window and set the device usage to "do not use this device in the current hardware configuration file (disabled)", that is, disable the camera in profile 1 (Figure 3 ).

Figure 3 when the camera is disabled and Windows is started, the hardware configuration menu appears, But the waiting time is only one second. Profile 1 is loaded by default after the system is started, and the camera cannot be used. If you want to use a camera, you can choose to load profile 2 or re-enable it in Device Manager.

Start the task plan of the system. Create a new task plan that starts at every Saturday and Sunday and runs every two hours. the user who runs the plan is a special account for children and the command is c: \ stop. BAT (figure 4 ).

Figure 4 create a task that starts at every day and runs at intervals of 1 minute until. The execution program is also c: \ stop. bat.
