Windows 7 enforces advanced security encryption features

Now many low-level operating systems have many security vulnerabilities by default. They are more likely to be attacked by viruses and Trojans, and virus Trojans will spread and spread through shared connections. Sharing is one of the important ways to protect network security. For example, to limit the Windows XP system to free access to resources in the Windows 7 system, as long as the 128-bit encryption function is enabled in Windows 7, forcing the client system to use the advanced security encryption method for shared access connection, the security of shared access can be guaranteed. The following are the specific activation steps: (1), click the "Start → Control Panel" option in the Windows 7 system, click on the "Network and Sharing Center" icon in the pop-up system control panel window, open the network and In the Sharing Center Management window, click the “Change Advanced Sharing Settings button” from the left area to enter the settings window shown below. (2), point the mouse to the "File Sharing Connection" location, select the "Use 128-bit encryption to help protect the file sharing connection (recommended)" option, and then click the "Save Changes" button.
This way, only the client system of Windows Vista or later can access the shared resources in Windows7 system in the future, while other low-level systems do not support advanced security encryption, when accessing shared resources in Windows7 system, only Can stay at the level of "discovery" and cannot copy or move shared files.
