Hello Jaq,

From Start Menu >> Run, type regedit and this will open the registry editor. Navigate to the path below :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

If the registry key Storage DevicePolicies key does not exist, you will need to create it.
Download the batch file called add.bat from below link, and double click after download the key will be automatically added to registry.
