Windows 10 - Network Not Showing

I set up file sharing direct between a windows 7 machine and a new windows 10 machine via a Ethernet cable. The windows 7 machine network is not showing on the windows 10 machine, but when I type "file://computername" in the windows explorer address bar I can get the windows 7 machine to be identified in the windows 10 machine's network - and I have no problem accessing files between the two machines.

How can I get the windows 10 machine to identify the windows 7 machine (under the Network) without having to type in the computer name each time as identified above?

Thanks for any comments.

That happened to many ( including me ) when ver. 1511 build 10586.104 came out but was fixed in ver. 1511 build 10586.122 and remains fixed in build 10586.164.
It's possible that you are missing an update, go to search and type in winver and click on it to see what version you are running.

but when I type "file://computername" in the windows explorer address bar I can get the windows 7 machine to be identified in the windows 10 machine's network - and I have no problem accessing files between the two machines.

That's what I had to do also and I made shortcuts by dragging that to my desktop for each networked computer until it was fixed but I left them there "just in case".
Hope this helps.

Thanks for the comments!
