you can force the automatic unload DLL when they are no longer used by the system by freeing the memory space dedicated to the cache and avoiding certain situations in a performance degradation.
Run the application regedit.exe and select the following key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer]
edit or create (if doesn't exist) the following value:
"AlwaysUnloadDLL"=dword:1
You must perform a reboot of your PC to activate the feature.
