Beware of aggressive APM on Windows 10 Build 1809

If your spinning disks are making clicking noises:

In Windows 10 the registry key is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStorAC\Parameters\Device

Create a new dword value named EnableAPM with a 0 value and hdd head parking is gone.

Note that iaStorAC might be iaStorA or iaStorAV in some cases.
