1) The Windows boxes are up to date. Microsoft releases a new version of 
Windows 10 every 6 months but continues to release updates for the older 
versions. This is similar to what Ubuntu does except that Microsoft 
doesn't label some versions as LTS and so far haven't dropped support 
for any version of Windows 10.

2) I don't want to directly connect to a Windows box. That would require 
opening up more ports on the router and giving hackers more targets.
