I have a 3 year old laptop running Windows 10 Anniversary Edition. It is having some issues that had me purchase a new laptop. I'll call the old laptop A and the new one B.
A and B have both been set up with the same Microsoft account. The network settings for both of them are identical: Network Discover is on, File and Printer Sharing off. They are on a private network behind a router, both on wifi. Under "Homegroup", A says it is ready to create. B says it is ready to join.
With File Explorer, under Network, both laptops show B listed, but A cannot see anything in it. Neither one lists A.
The first puzzling thing was related to the desktop. I had not transferred any files or pictures from A to B yet. (Family crisis, didn't have time.) On A, I have the background display set to a slideshow in a specific folder which only resides on A's hard drive. It is not stored in the cloud anywhere. B has a few pictures that came preloaded on it. I chose one of those factory pictures for the desktop background display. I walked into the room where A was, and THAT picture was on the desktop background. I changed it back to slideshow, to a different folder of pictures that resides on A's hard drive.
Today, I powered up B, and shortly after the desktop loaded, the background changed to one of the pictures from the folder that only resides on A's hard drive. I'm curious about why that happened.
I don't really understand networking and I don't need to set up any file sharing between these two laptops. A is going to be out of commission when I have the time to get B set up properly. I'm just curious about why the display settings on one impact the other.
I'm trying to get the Anniversary Edition installed on B, but so far, B is refusing to find it. Aha, even as I typed that, B finally did find it and it's probably getting it from A, judging from the download speed. (I have satellite internet, download speed is not great.)
This is a trivial topic compared to most others here and not a problem per se, I just wondered if anyone might have the time for a quick explanation.
