April 2018 Windows Update -- Can't see network on all machines.

This is what Microsoft recommends:

Explorer Network Browsing

The Computer Browser service relies on the SMBv1 protocol to populate the Windows Explorer Network node (also known as "Network Neighborhood"). This legacy protocol is long deprecated, doesn't route, and has limited security. Because the service cannot function without SMBv1, it is removed at the same time.

However, if you still have to use the Explorer Network in home and small business workgroup environments to locate Windows-based computers, you can follow these steps on your Windows-based computers that no longer use SMBv1:
Start the "Function Discovery Provider Host" and "Function Discovery Resource Publication" services, and then set them to Automatic (Delayed Start). When you open Explorer Network, enable network discovery when you are prompted.

All Windows devices within that subnet that have these settings will now appear in Network for browsing. This uses the WS-DISCOVERY protocol. Contact your other vendors and manufacturers if their devices still don't appear in this browse list after the Windows devices appear. It is possible they have this protocol disabled or that they support only SMBv1.

I'm not sure this applies, because I'm not using a legacy machine.  It's a two year old Dell XPS

Thanks for the tips Andre.

My network has three computers:

1) Dell XPS 8900 desktop running Win 10 Pro April 2018 update 1803 (~2 years old)

2) Dell StudioXPS 435T Desktop running Win10 Pro April 2018 update 1803 (~9 years old)

3) Lenovo Flex3 1580 Laptop running Win10 Home April 2018 1803 update  (~ 2 years old)

I removed the 1803 update on the XPS 8900, but it re-installed itself. After the reinstall, I can see both the Flex3 and the 435T from the XPS 8900 with full read and write privileges.  I can see the 435T from the Flex 3, but can't see any the XPS8900 from either the 435T or the Flex3.  The XPS 8900 to Flex 3 communication is critical to me, and I can live with it the way it is now, but it would be much more convenient to be able to push files from the Flex 3 to the XPS 8900.  Should I be able to do that?

Do this on the computer giving problems.

Open Start > Settings > Update & security > Troubleshoot
Scroll down
Click Network adapters
Click Run the Troubleshooter

When complete, restart to see if the problem is resolved.

If not, press Windows key + X
Click Device Manager
Expand Network adapters

Right click your adapter
Click Uninstall

Exit Device Manager, restart. Windows 10 should detect the network adapter then reinstall it. Check if you can connect and browse.

also try:

Open Start > Settings > Network & Internet > Status

Scroll to the bottom then click Network reset.

Disable Energy Efficient Ethernet in "Client for Microsoft Networks"

Basic Question:

Should I be able to see and access all the computers logged in to my (private) network from any computer on the network no matter which computer boots first? I'd like to use all three computers as terminals so that I can copy files from one machine to the other.  All machines are used in different locations with different software.

One desktop and the laptop are connected by wifi.  One desktop is hard wired.  As it is now, the first computer I boot sees and has read/write privileges to the whole network.   The other wifi and hard wired computers can't see the computer that booted first.  This was confusing at first because the network owner moved from machine to machine, depending on boot sequence.  It also means that the first computer  booted (network owner) is the only one with Read/Write permissions.

Would it matter that I use the same log on with all three machines?

If I made my network public, but my router is password protected and only three computers have the password, would any other machines be able to access my network?

I have image files of all three computers.  Am I correct in assuming that I won't be able to get an ISO for the version of Windows prior to the April 2018 update 1803?  Am I correct in assuming that after May 10, I won't be able to revert to an earlier version of Windows without using those image files?

Follow up to the Andre's email immediately proceeding.

When I get to "Client for Microsoft Networks" the property box is visible but can't be clicked.
