Lost trying to make Hyper-V functional

I was attempting to follow a straight-forward seeming tutorial at eightforums, regarding enabling a virtual switch, for a not-yet made virtual machine. I want to try out some virtual OS's on my PC, just to see what happens - I would like to test drive Win 10 if that is feasible.
 
When I attempt to create a virtual switch, the option to create an external switch is unavailable. 

 
This may or may not be related to something I discovered about my NIC, after reading an online posting, from some site or other, regarding similar Hyper-V difficulty. The box next to the Hyper-V Extensible Virtual Switch property was not checked. I checked the box, immediately prior to making a screen capture with One-note clipper. 
 

 
just checking the box did nothing, when I still couldn't create an external switch, and went back to look at my NIC's properties, that box was unchecked again. I attempted to install the Protocol for the Hyper-V Extensible Switch, and that's when things went sideways. Most or all of the other property boxes became unchecked, and I lost internet access. I don't know why that happened.
 
I used system restore to restore my NIC settings to how they were, and decided I should get some help, since I am obviously a little out of my depth here.
 
Anyone clue me in as to how to get Hyper-V functioning so I can run a virtual OS with internet access?

Moved from Windows 8

Opening hyper-v manager over on the left side do you see your computer name?

yes

Go to network and sharing center and change adapter settings. Right-click the nic and go to properties and sharing. Put a check in the box.

this pops up

In case there is any question - I clicked 'No', since I am sure that selecting 'Yes' would have resulted in losing Internet access like happened previously.

Is this an external nic or internal one?

In your network properties uncheck the box for Hyper-V Extensible Virtual Switch & then try it.

the NIC is on my motherboard

 

that box is already unchecked. I think that checking that box leads to disabling every other function of my NIC, at least that is what seems to happen

That's strange mine is the opposite if I put a check in it. Says doing this will disable Hyper-V Extensible Virtual Switch. I have the exact same nic as you. Maybe try downloading a new nic driver from your motherboard manufacturer? I can create switches fine with it unchecked.

 

Edit: Try uninstalling the protocol and reinstall it.

Maybe it is something else entirely then?

 

I will look for a more recent driver 

Not sure what your motherboard model is, but I have a Asus and they do have a Windows 10 driver specifically for lan that is dated 07/31/2015 when it came out.

That's the driver I got now on my system Asus.

 

Realtek LAN WIN10 32bit&64bit V10.1.505.2015

mine 8.38.115.2015

 

mine was released 1/15/2015 and is for windows 8. I think there is a more recent one 8.040, which I am downloading

updated to latest driver for my NIC and rebooted. No difference

 

uninstalled Hyper-V Extensible Virtual Switch protocol, and re-installed it. Still no option to create external Virtual Switch in Hyper-V manager
