One way to minimize this problem is to turn off the computer every time you leave your workplace. In this case, the potential spy, if you want to get to the protected files, will have to go through the login procedure. Obviously, this method is very impractical and inconvenient.
Is there a more convenient way? Of course, it consists in blocking access to the computer before leaving the workplace. In this case, anyone who wants to use a computer will be forced to enter a password to gain access to the Windows desktop.
Manual computer lock
Windows 7 offers three ways to lock your computer before leaving the workplace.
- Menu selection Start teams Shutdown > Block.
If you need to block the computer regularly, you should consider turning the button with the Shut down command into a button with the Block command.
- Simultaneously pressing a Windows logo key and key
- Press a key combination and then click on the Lock computer option.
If any of these methods are used, the Windows registration screen appears. It is important to note that the word “Blocked” is displayed under the username on it.
Automatic computer lock
The blocking techniques described in the previous section are not complicated; the main difficulty is to remember the need for their application. For example, being late for a meeting or meeting, who will remember that you need to lock the computer? In such situations, it usually happens that a person comes to the appointed place and only then remembers that he forgot to lock his PC, after which he begins to suffer from the thought that he left his computer unprotected.
To avoid such difficulties (not to mention possible penetration), it is better to configure the computer so that it locks automatically after a certain period of inactivity by the user. In previous versions of Windows, a screen saver was required to provide this behavior, and Windows 7 is no exception. The necessary steps are given below.
- Right-click on the desktop and select Personalization from the context menu to open the Personalization window.
- Click the Screen Saver icon.
- If you want a screen saver to appear after the PC is idle for a while, select it in the Screensaver list.
- In the counter field, specify the idle interval (in minutes), after which Windows 7 should automatically lock the PC.
- Check the box next to the Start from the login screen option.
- Click on the OK button.

Protecting a user account with a password in Windows 7, although it is a wonderful idea, still does not give a one hundred percent guarantee. Hackers are a very ingenious public, and some of the smartest of them have already figured out how to crack an account password system. Their trick is this: they install a virus or program like a Trojan horse (usually via an infected email message or a malicious website) in the system, which loads itself when the user turns on the computer.
Further, this program displays a fake version of the Windows 7 welcome screen and records the user name and password entered on it by the user, after which the system’s protection is compromised. You can eliminate the possibility of falling into such a hacker trick in Windows 7 by setting up the system so that users had to press a key combination before entering
Pressing this keyboard shortcut ensures that the Windows 7 Welcome screen appears. The following are the steps required to configure this behavior.
- Click the Start button, enter the command line, in the list of search results, right-click on the Command line option and select Run as administrator in the context menu. The User Account Control dialog box appears. Enter your user credentials in the User Account Control window.
- At a command prompt, type control userpasswords2. The User Accounts dialog box appears.
- Click the Advanced tab.
- Select the Require CTRLALTDELETE check box.
- Click on the OK button.
