For one or another reason you may be in need of changing your network type from Internet to Private in Windows 8.1/10. For example you can’t join HomeGroup when you connected to Internet type network (being on Domain or Private network is a requirement for this, as well as IPv6 enabled on your network adapter, plus bunch of services in running state). But in my case I had an issue when I installed Windows 10 TP on my main desktop which I usually access via RDP from my laptop. I lost RDP connectivity just because Windows 10 defined my Ethernet connection is of Internet type instead of Private, and I seen this more than once (when changing Windows 10 builds). I’m really wondering how it detects/decides on network type?. Of course you can go and adjust firewall rules for Internet network profile, but this is wrong approach. Though it was something what I used as a quick fix as a way/place where you change your network type from Internet to Private is a bit counter-intuitive/difficult to find.
So I’m just noting how to do this on Windows 8.1/10. In order to change your network type from Internet to Private you should do the following:
Go to Settings (either by accessing respective charms icon or by pressing Win + I) > Change PC Settings > Network > Connection. There you have to click on your connection and enable “Find devices and content” option. Once this is enabled your network type is changed to Private.
