Group Policy method, Isn't that time limited also? I have read (right or wrong) that even doing it via Group Policy, eventually, Windows 10 will update itself regardless, so I didn't bother pursuing that avenue after my experience with disabling the Win Update Service, assuming all bases would be covered by Microsoft one way or another.

I did some digging into this and the nerd squad all say the same thing,, eventually, all versions of w10 will update because of security issues. This can be delayed with the Business gizmo in pro but only about 6 months, So it's a loosing battle. I have Sonar Splat and Home Studio on
3x W 7
1X W 8.1
3x W 10
 
We'll see how it pans out. My main DAW is 8.1 and so far it's smooth sailing. I'm pretty fed up with re authorizing AD2 and iLok and e licencer just because W10 screws this up.

You could also additionally to ensure not accidental discover IP again by your computer to block access on router if possible (your ethernet card has unique MAC address).
 
For instance exclude that computer from beeing served by DHCP service on router and if possible (depends on router - creates direct rule to block it).

This method will kill the local LAN as well.
If you want to completely disable the internet you just need to disable the network adapter in device manager, that's it. Sure add a rule if you are paranoid it may get reenabled.
If you want LAN but not internet then remove the gateway.

This may not be what you are looking for, but there is a freeware program you can get that allows you to right click your mouse over it's icon in the task bar after you've installed it to turn the internet connection on or off, you can turn it off for a predefined amount of minutes or for good until you want to turn it back on again using the program. You can also schedule when you want your PC connection to the internet on or off.
