I. What is Group Policy
(1) What is the use of Group Policy?
When it comes to group policy, you have to mention the registry. The registry is a database for saving system and application software in Windows. As Windows functions become more and more abundant, there are more and more configuration items in the registry. Many configurations are customizable, but they are published in every corner of the registry. If it is manually configured, it can be difficult and complicated.
