Win10 How to close windows defender

Windows Defender is the system's own defense tool. Windows Vista and later versions of the system are built-in. I think it is not powerful enough and will take up system resources. I used a third-party defense tool to close it. Is the best choice.
Use the shortcut key (WIN+R) to bring up the running tool, then enter the group policy command (gpedit.msc) and click OK.

Entering Group Policy In the computer configuration below the administrative template, Windows components can see the same as Windows Defender. Double-click Windows Defender, double-click to close Windows Defender

and select Enable
to finalize.

Go to the Control Panel and run Windows Defender

Try it. You will be prompted to close this application by Group Policy. In other words, this program is not used now.
