Might it be helpful to beef up the SystemInfo command to return more specific information about the version of Windows running as an aid to troubleshooting? For example:
The full Windows version can be had programmatically from:
Environment.OSVersion
The release number, as in “the 2004 update”, can be had from the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
under
ReleaseID
(at least for Windows 10. The installation date is there too, albeit as the number of seconds since January 1, 1970)
