Default Duplications in network

Wireless network links three PCs:
Laptop Win7 Pro
Downstairs Win7 Home
Upstairs XP
but this displays today as
Laptop Win7 Pro
Laptop Win7 Pro
Laptop Win7 Pro: User
Downstairs Win7 Home
Downstairs Win7 Home
Upstairs XP
Upstairs XP
(and I have access to Upstairs but not Downstairs . . .)

Does this mean anything in particular?

I've no idea, but it might help others to help: it displays today as the
above _on what_ - the laptop, the XP, or both?

How many networks are you running ? Are you using Ethernet
and Wifi at the same time ?

Are you a user who has followed a tutorial to
use both HomeGroup and WorkGroup at the same time ?

Windows 7 can use LLDP (link layer discovery protocol) to
build a GUI network map. The GUI portion was removed from
Windows 8 and 10, so only Win7 has this. I don't think
it would add any value in this case, as legacy subsystems
are doing the network detection you see currently. I have
no idea what this might display, or whether it would give
any hints. AFAIK, this subsystem has no impact on regular
network operation. LLDP is not used to actually find
things to file share with, for example.

Another possibility, is DHCP gave out a new set of IP
addresses (lease renewal). Maybe you reset a router
to defaults and set it up again ? The Windows OSes
"remember" previous discovered machines for a short
time. And that's the most worrisome part about the
Windows networking, is the insistence on saving
"stale" detections. When I change OS drives on my
second active computer, I will find the old identifier
still in my Network Neighborhood. If I were to turn off
all the computers, and let them discover from scratch,
that could clean it up.
