Windows 10: Will resetting Windows 10 to factory settings if 7 was the stock OS reset it to 7 or 10?

I am considering buying a refurbished laptop from Amazon. The OS that was installed when the laptop was new was Windows 7, but the owner upgraded it to 10. If I bought it, I would probably wipe the drive for a clean slate. Would going to settings and reset this PC and removing all files reinstall Windows 10 like it would if that was the stock OS or would it reinstall 7?

How to reset whole netsh? (Windows 7)

Was wondering has the commands changed somehow since on Windows XP and on Windows Vista 'NETSH INT RESET ALL' cleaned entire netsh up from top to bottom.

Now on Windows 7 this same command says no go and only way I can see it is by building .cmd/.bat which does something like:

Code: netsh winsock reset all netsh int 6to4 reset all netsh int ipv4 reset all netsh int ipv6 reset all netsh int httpstunnel reset all netsh int isatap reset all netsh int portproxy reset all netsh int tcp reset all netsh int teredo reset all[/quote] now the king of the hill of bugs is this doesn't actually do even it's job even after reboot. values setup to are not reset to defaults. (I know I could add more entire list of entries there is, but looking for clean delete/wipe settings & default everything not to dump entire list of resets.)

So, anyone got a plan B?
