[PATCH v2] services: Allow reading binary registry values as DWORDs

[Tim Schumacher]

Some programs/services actually save those values as a registry
value of the type REG_BINARY. As long as the size matches, it
shouldn't be a problem to just interpret it as a DWORD type,
but warn anyways in case someone runs into issues.
