private to public network

I have struggled with this repeatedly with Windows 7 and Windows 10. While there are solutions out there that describe how to change a network from Public back to Private (And not all solutions work because sometimes the options are not visible within Network and Sharing Center), I still cannot find out why this happens and it doesn't matter whether it is in a domain environment or workgroup environment. Is there a Windows Update that causes this?  I don't know, can anyone shed some light on this as to why this happens?  Why does a network, out of the blue for no apparent reason, switch from Private Network to Public network making the internet inaccessible?

You can sometimes change the setting by clicking on the NIC profile and change the properties. This does not always work and then you need to remove the connection profile and remake it.

The very newest version of Windows 10 (V1709) fixes this and allows you to change the setting using Windows 10 Settings
Based on my understanding from the article below, Windows will "attempt" to make a determination about the network using NLA.  The article has some suggestions (towards the bottom) regarding how to control this with Group Policy, so you might start there as far as how to force your system to remain on Private and not flip over to Public:

I would like to accept the answer by John Hurst, since we have all upgraded to Windows 10 and the latest 1709 upgrade did fix the issue.
