Win 7 system screen saver setting method

Many children's shoes like tree trees like to get a screen saver for the computer. When they leave the computer, the screen saver will block their "privacy", which is very useful in the office. But after everyone used Windows 7, they found that the screensaver in the "display properties" is now gone! I have been looking for a long time and have not found it. Once suspected that Windows 7 does not have screensavers. Finally found that Windows7 will move the screen saver!
The screensaver after moving, arrived at the "Personalization" option in the "Control Panel". After entering the "Personalization" dialog box, in the lower right corner of the dialog box, find a "Computer + Prohibited" icon, click on it, you can set the screen saver.
