How to make the Windows system automatically release resources

If someone asks you, how does the computer make the Windows system automatically release resources? Here I share the tips I have learned over the years!
Automatically Release System Resources Every time you run a program in Windows, system resources are reduced. Some programs consume a lot of system resources. Even if the program is closed, there are still some useless DLL files running in memory, which makes the system slow down. However, we can modify the registry key value, so that after the software is closed, the unused DLL files in the memory are automatically cleared to recover the consumed system resources in time. Open the Registry Editor.
Find“HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\explorer” Primary Key
Right click on the right window and create a new string named "AlwaysUnloadDll"; ;, then modify the key value of “AlwaysUnloadDll” to “1”,
Exit the registry and restart the machine to achieve the goal.
This is not very simple! I believe that no matter what kind of rookie has learned!
