Latest WIN 10 Update

I never used homegroup but LAN networking stopped too. I'm trying THIS

I haven't tried this but it seems to address your problem.

Homegroup Disabled

When I first saw your post I thought it might be related to a problem I was having with a network-attached storage device I was using. The 1803 update disables SMBv1 which they say is a terribly vulnerable file sharing protocol. Unfortunately a lot of older NAS devices, like mine, rely on it. This could also be your problem. I re-enabled it despite the dire warnings not to. Here's more info on that.

SMBv1 Disable/Enable

FYI. You can no longer disable or remove OneDrive. Perhaps it is related?

You're lucky you didn't lose your network altogether. A number of network cards are being killed or even crashing Windows while loading (Wifi mostly) in this latest update.

Part of the problem is old drivers that are no longer compatible. MS provides a number of drivers, but Win 10 upgrade cannot properly remove the old drivers and fails to flag it to download new drivers BEFORE crashing the system.

Interesting you have lost just file sharing. I haven't heard about that yet.

I have been ignoring the cloud ever since I have heard about it hehe... Sounds like I better get started to using it... I'm probably using the cloud and don't even know about it...

For some reason I just feel better having my backup files on my own hard drive here in my hands... Who knows who is viewing my files when in the cloud...

I remember way back when in the early 1960s WINDOW days MS was sending everybody's files to a place in Australia for whatever reasons...
