[host] windows: read ProductName from registry if possible

Browse Source 
For Windows 10, it so happens that the major.minor is 10.0. This is not
usually a given, e.g. on Windows 7 where it would read 6.1, on
Windows 8 it would read 6.2, and on Windows 8.1 it would read 6.3.

This is obviously undesirable, so we should just read the ProductName
from registry if possible. This results in something like:

    OS Name: Windows 10 Pro for Workstations (Build: 19043)
