+ Parameters Description:\r

+ driver is loaded, and it is released by the system after the system unloads\r
+ the function driver from memory.\r
+\r
+ RegistryPath - represents the driver specific path in the Registry.\r
+ The function driver can use the path to store driver related data between\r
+ reboots. The path does not store hardware instance specific data.\r
