Too bad. That sounded so good.
Well, mine is 1809 with that latest update & with both Ethernet & Wi-Fi adapters. With only one computer, I never do file sharing & hardly even knew that Network folder existed (or anything else about it). The folder is empty until I switch to
Private at "START, Settings, Network & Internet, Change connection properties"...

Then, it fills with stuff...
.
I plugged in my Ethernet. It turned ON & Wi-Fi also remained ON. After a
reboot, not only did nothing disappear, but a second "computer" called "full_biscuit" was there. I checked its properties & it appears to be an Amazon thing.

But the question is - am I unafflicted with the Network folder problem?
