How can you move the folder Dllcache?

The folder DLLCache contains the system files needed to function "Windows File Protection".
This prevents programs from overwriting important files necessary for the proper functioning of the operating system itself.
To change the folder location DLLCache, run the application regedit.exe and select the following key:

[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon]

edit or create (if doesn't exist) the following value:

"SFCDllCacheDir"="%SystemRoot%\System32" (valore predefinito)
