If you set the Firewall to the max (disable ANY incoming traffic), it will more or less be invisible. Depending on how advanced the network equipment is there, the NORMAL clients won't be able to scan you (normal Windows, iOS, Android devices), while the top admins in charge of high level network equipment will pick up on your presence if you do anything network related (browse the internet etc).

If you wish to browse and get email (that is, accept incoming packets) you cannot really hide.

There is nothing different in Windows 10 in this regard than any earlier Windows going back decades.

So is this a Windows 10 issue for you (so then, specifically what)?

Or is this a general Windows security issue?

We remember in Windows 7 there was an option in the OS that would disable the device from broadcasting itself to the LAN.  We did this before but can't seem to find how to do it..

Use fixed IP address, set firewall to close EVERYTHING.
Control Panel > Network and internet > Network and Sharing Center, go through all the options, disable everything.

Here is the Microsoft TechNet on disabling broadcasting.

It does not mean you can hide from everyone.

Of course, we understand that there other ways LAN admin can do to identify presence of our PC connected to their network, but as long as we can stop the PC from sending the LANs it connects broadcasting its presence, it's what we want.

Ok we will check.

Check the article again.

1. Go to Network and Sharing Center and turn off Network Discovery
2. Go to Advanced properties for the NIC and turn off LLTD (Link Layer Topology Discovery)

But wouldn't that affect our normal day-to-day LAN communications? (we don't want fix one thing and damage another normal Windows function)


[there was a procedure in Windows 7 that we just can't find]

I have not seen any setting (Windows 7, 8 or 10) that will allow free access to LAN and at the same time hide from the LAN. That is a Holy Grail that does not really exist. You can run but not hide.

Removing Link Layer should not impede LAN (try it) but it will impede Internet.

Turning off Network discovery does not impede LAN access - map by script.

We need Internet.

What we are looking for is the ability to actually halt the Windows apps to broadcast its presence in the LAN that it would be connected.  In previous version we have done this and had no problem with LAN or Internet.  Windows 10 has to have it also.

Still looking.

What you fail to understand is Windows 10 is NOTHING like Windows 7. Just because you found an obscure way in Windows 7 (that was probably a security hole) is no reason to believe the lack of security will be maintained in Windows 10.

What are you running and hiding from?

This is no issue at any of my clients.

Are you saying that this cannot be done in Windows 10?

I do not see any way to do it in Windows 10. Certainly no native way. Unless you can post it, there is no native way in Windows 7 or 8.1 either.

That is more a hack than any native service and not really necessary in my environment.

The same registry entries are in Windows 10 if you wish to use them.  You can add the key.
