Windows 10: Other computers in network not showing; shows old network instead.

Preface: I am running a laptop which I upgraded from windows 7 to windows 10. I also have a desktop that is still running windows 7. One of the hard drives on my desktop is shared, and I often-enough will copy files from my laptop to my desktop. The laptop connects wirelessly and the desktop is wired.

Today however, I could not get my laptop to see my desktop on the network. It is connected to the network; I am receiving internet just fine.
When I first click the network tab in the navigation pane, it does not list any section for any computers. So I tell it to refresh, and after a moment, it now displays three computers, all of which were ones I would see on the network from a house I no longer live in.
Now as it just so happens, one of those computers is my desktop, as I had it back then, but when I try to access it, it just gives me the spinning wheel for a while, and then just says it can't access it. If I click "diagnose" it doesn't find anything that's wrong. This is pretty much the same result I get form trying to connect to one of the computers from my old house.

I haven't changed any settings, and I was indeed able to connect to that computer at this house just a week or so ago.

Not sure what the problem is, but I haven't tried much other than resetting the computer. I'm open to suggestions.

Try this.
Windows 10 changed from smb2 to smb3

Command prompt / administrator and type two lines together like that :

sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsi
sc.exe config mrxsmb20 start= disabled

Reboot the pc when done.
