The one about RegSetValue(), according to Microsoft

https://msdn.microsoft.com/en-us/library/windows/desktop/ms724922(v=vs.85).aspx

the last argument cbData is ignored, so I set it to 0, as in some cases was anyway wrong (see "DiskImage").

* Use sizeof() rather than hardcoded value.
Fix one more case on non terminated string.
