[1] Improved User Account Control (UAC)
User Account Control (UAC), in fact, many people are no strangers, there is in Windows Vista, but has been criticized, as long as the user is a little on the computer system Change, it will frequently pop up a dialog box to seek the user's permission, while the screen is dimmed, this method improves the security of the system, effectively prevents viruses and Trojans from damaging the system, but at the same time makes the user feel very It's cumbersome, so it's one of the most hated features in Windows Vista.
In Windows 7, let users choose the UAC notification level. The biggest improvement in User Account Control (UAC) is that the control panel provides more control options, and users can choose the appropriate UAC level according to their needs.
Go to the Control Panel's "User Account" and click "Change User Account Control Settings". The UAC settings under Windows 7 provide a slider that allows the user to set the level of notifications. You can choose from 4 levels. You can personalize your choice according to your personal preferences, eliminating the harassment of the old pop-up prompts.
[2] Powerful Windows Firewall
Windows 7 The previous system generally also has its own firewall, but the function is simple, generally regarded as a chicken rib. This Windows 7's own firewall has been greatly improved. The function is relatively powerful, open the "Windows Firewall" in the control panel, its biggest feature is internal and external defense, through the "home or work network" and "public network" to protect the computer.
Especially the "advanced settings" feature is more comprehensive, comparable to the general professional firewall software, through the inbound and outbound rules can set the application to access the network, and the monitoring function can clearly reflect the current network In the case of circulation, (Figure 1), you can also set custom inbound and outbound rules. I believe that the Windows 7 firewall will have more users to use.

[3]Parental Control Function
In Windows 7, there is a parental control function. Through this function, parents can control the child's use of the computer, such as the time of using the computer. What kind of games can be played with a computer, which applications can be run, and which programs can't be run, can be personalized to ensure that children use the computer safely and reasonably.
The following describes the method: first create a standard account, you can not set a password for the child to use, and then set a password for the administrator account to prevent children from using, open the control panel in the "parent control", select just created A good user can set parental control for the user (see Figure 2), click “For the child's account”, standard user, select “Enable, apply current settings”, and then set “Time limit” ; You can set whether you can let your child use the computer at any time of the week, control the time period when the child uses the computer, set the level of the game the child can play, and block specific games.

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.
[4]Windows BitLocker Drive Encryption for File Security
Windows BitLocker Drive Encryption is a new security feature that prevents unauthorized users from accessing all files under the drive. This feature is encrypted by the Windows operating system. All the data stored on the 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 the control panel and select “BitLocker Drive Encryption” to select the encryption. Drive letter, click “ enable BitLocker ”, then, you will be prompted to initialize the drive, and then set the password for the drive encryption, (Figure 3), click <; next & rdquo;, in order to prevent forgetting the password, you can also set BitLocker restores the key file, and finally clicks “Enable Encryption” This way, if you want to access the disk drive, you will need to enter a password.
