The following are some very useful features that Windows 7 brings to us in terms of security. I believe that with it, let us use computers more securely. We are still concerned about the security of the system. Windows 7 is more secure than previous systems. Big change, the author will take everyone to experience the security performance of Windows7.
a parental control function
have a parental control feature in Windows7, through this feature parents can control their children's use of the computer, such as the use of computer time, use of computers can play what kind of game, which can use the program to run, which can not run, you can personalize to protect children using computers safe and reasonable, the method described below:

This can limit your child's use of certain applications, such as not allowing children to use QQ, not allowing programs that use improper operations to corrupt data.
Second, the improved version of the User Account Control (UAC)
User Account Control (UAC), in fact, many people are not familiar, in WindowsVista in there, but has been criticized by others, As long as the user makes a slight change to the computer system, it will frequently pop up a dialog box to seek permission from the user, and the screen will be darkened. This method improves the security of the system and effectively prevents viruses and Trojans from damaging the system. At the same time, it makes users feel very cumbersome, so it has become one of the most hated features in Windows Vista.
In Windows7, began allowing users to select UAC notification level, the user account control (UAC) is the biggest improvement in the control panel offers more control options, the user can select the appropriate needs according to their level of UAC .
into the Control Panel's "System and Security" in the "operations center" in Click "Change User Account Control settings", UAC settings under Windows7 provides a slider allows the user to set the notification level, you can Choose 4 levels, you can personalize your choice according to your personal preferences, eliminating the harassment of the old pop-up prompts.
three, WindowsBitLocker Drive Encryption to protect document security
WindowsBitLocker Drive Encryption is a new security feature, users can prevent unauthorized access to all files in the drive, the encryption function All the data stored on the Windows operating system volume can better protect the security of the data in the computer. This function is very useful for both individual users and enterprise users. Open "System and Security" in the Control Panel and select "BitLocker". Drive Encryption", select the drive letter to be encrypted, click "Enable BitLocker", then you will be prompted to initialize the drive, and then set the password for the drive encryption, as shown in Figure 4, click "Next", in order to prevent forgetting the password, You can set up BitLocker recovery key file, and finally click "Enable encryption". This way, if you want to access the disk drive, you will need to enter a password.
four powerful Windows Firewall
Windows7 previous systems generally have built-in firewall, but features a simple, generally regarded as tasteless, this comes with a firewall Windows7 do a lot of Improvements, more powerful, open the "system and security" in the control panel to see the Windows firewall, its biggest feature is internal and external defense, through the "home or work network" and "public network" two aspects of the computer Take protection.
especially the "Advanced Settings" which is more comprehensive, and generally comparable professional firewall software, you can set the application to access the network situation through inbound and outbound rules, additional monitoring can clearly reflect the current In the case of network circulation, as shown in Figure 2, you can also set custom inbound and outbound rules. I believe that Windows 7 firewall will have more users to use.
