Windows7 system optimization makes the system more secure (1)

Virus and Trojans and other malicious programs are spreading faster and faster. Once you are recruited, it is easy to cause system crash or personal privacy leakage, and it may cause loss of property. Network security issues also exist in Win7. How to optimize the win7 system to make the win7 system more secure? Below we have targeted security optimization for Win7 systems.

Close the default share Block the back door of the system

Like XP and Vista, Win7 also enables network sharing by default. Although this makes LAN sharing more convenient, it also creates conditions for virus transmission. Therefore, turning off the default share can greatly reduce the probability of the system being infected by a virus.

Open the Rubik's Cube, click "System Optimization → Network Sharing", select "Disable default management sharing and disk partition sharing", click "Save Settings" and restart the computer. At this time, you cannot access the system through the default share. It is. If you don't want to turn off all default shares at once, the cube also provides the ability to turn off a single default share. In the previous interface, select the "default share" point "refresh", you can see the current system's default share list, select the default share that is not needed, click "Clear Share", save the settings to restart the computer, the selected default share will is closed.

In addition, Rubik's Cube also provides settings such as "Restricted IPC$ remote default sharing" and "Disallow inter-process communication IPC$ empty connection" to improve system security. It is recommended to enable all.

Modify Group Policy Reinforce System Registry

Same as XP and Vista, Win7 still has a very high risk of remotely accessing the registry path. Setting the path to the remotely accessible registry to null can effectively prevent hackers from using the scanner to read Win7 system information and other information through the remote registry.

Open the Control Panel, select "Administrative Tools", double-click "Local Security Policy", open "Local Policies→Security Options", and then find "Network Access: Remotely Accessible Registry Path" on the right side and "Network access: remote access to the registry path and sub-path", double-click to open, delete the registry path in the window.

Lock important features to prevent virus theft

The system has some commonly used, high-privilege features, such as command line programs, batch files, registry editors, etc. are often malicious by viruses. Software utilization has become an "accomplice" to the intrusion system. These programs are not commonly used as ordinary users. Therefore, disabling these functions can effectively strengthen the system and ensure the security of daily applications.

Open the Rubik's Cube and select "Security Optimization → System Security Settings". It is recommended to select "Disable Management Console (MMC) Plugin", "Disable execution of autoexec.bat file", "Prohibit editing with registry", " It is forbidden to import .reg registry file, "disable command line program and batch file", save the settings and restart the computer to complete the setting.

Disabling automatic operation Preventing virus propagation

In addition to networking, mobile storage devices such as flash drives and mobile hard drives have also become important ways for malicious programs to spread. When the system has autoplay or autorun enabled, malicious programs on the removable storage device can infect the system without the user being aware of it. Therefore, disable the auto play and auto run functions, which can effectively cut off the propagation path of the virus.

Turn off autoplay: Enter "gpedit.msc" in "Run" to open Group Policy Manager, open "Computer Configuration→Administrative Templates→Windows Components→AutoPlay Policy" and double click "Close Autoplay" , click “Enabled”, select “All Drives” in the options, and finally click OK, the auto play function will be turned off.

Turn off automatic operation: Double-click "Default behavior of automatic operation" in the same position, select "Enabled", select "Do not execute any automatic running command" in the option, then click OK, the automatic running function will be closed.

Restricting system functions to ensure system security

If the computer is placed in a public environment such as a dormitory or a company, it is very important to limit important system functions to prevent other users from causing system failure. Important.

We can use Rubik's Cube in the "System Settings → Taskbar and Notification Area", "System Settings → Start Menu", "Security Optimization → System Security Settings", "Security Optimization → Control Panel" and other modules. Make further settings, such as disabling the control panel, disabling management tools, disabling the taskbar right-click menu, and more. These functions are not only simple but also effective, and you can choose to use them according to the specific use environment.

Clear

History Protects Personal Privacy

One of the features of Win7 is the ability to record users in multiple locations, such as the Start menu, Taskbar, and Explorer search bar. Operation history. Although convenient, it sometimes leads to the leakage of personal privacy.

It's easier to close the history menu and the history function in the taskbar. Right-click on the taskbar, select "Properties" from the pop-up menu, and then uncheck all of the "Start Menu" → Privacy items.

But in the Explorer search bar The history must be cleared using Group Policy. Enter "gpedit.msc" in "Run" to open the Group Policy Manager, open "User Configuration → Administrative Templates → Windows Components → Windows Explorer", double-click "In "Close the display of recent search entries in the Windows Explorer search box", select "Enabled", and then close the group policy after confirmation. This way not only the original history is gone, but we will not record our operations here again.) Br>

After a series of win7 system optimization, our Win7 system network security is basically guaranteed. However, we still need to install the system patch and update the anti-virus software virus database in time, do not log in unknown website, only in this way can Win7 maximize Stay away from security threats and keep it running.
