How to safely remove LAN?

[Terry Pinnell]

I'm a standalone user of this XP Pro (SP2) PC, with a simple broadband
connection via router. Networking remains a black art subject to me.
But a year or so ago my son installed a facility (LAN?) to allow me to
easily transfer data from my old PC to this one. I've long since
removed that cable and PC, which I no longer need.

So, to make occasional trouble-shooting of various problems easier,
and to potentially improve performance, can I now remove any
components of this LAN please?

I suspect this may not be a clear enough description, due to my
ignorance of this aspect, despite many years of fairly complex PC
usage. So I'll happily provide any other information if it helps,
including screenshots, service lists, Task Mgr details, etc.

If there's a more appropriate group, please advise.

Go into My Computer > Tools > Disconnect Network Drive
Go into Windows Explorer
Look for a drive icon with a HAND under it
Properties > sharing and security > uncheck any boxes Reboot

Let me know if I was correct

Thanks Ken. That gave me the message "You have no network drives to
disconnect." What is a 'network drive' anyway please?

Unfortunately there isn't really enough information here. Is there
something that you see, an application perhaps, that you could identify?

It may be that what was installed can be seen through the properties for the
network adapter. But you don't want to go removing components there, as
some are definitely needed for your broadband connection.

On the upside, there is likely little or no negative impact on system
performance if you leave things as they are.

LAN stands for Local Area Network, and these days it usually means that
you've got a router that allows connection of several systems. The router
plugs into your broadband connection, handles any logins, and also provides
a good level of protection from the outside network (the WAN, or Wide Area
Network).

Control Panel\Network Connection and highlight the LAN connection and use the delete
key and remove. That is all there is to it

Thanks Patrick. I'll take your advice and leave it installed then! But
I fret about all those entries I see if I run Process Monitor for a
second, that appear to be concerned with networking, like this tiny
sample lasting a few microseconds showing Tcpip processes?

It just seems that if my CPU is constantly checking network stuff,
when all I have is a router, then it must be slowing it down.

*Every* action involving TCP/IP is concerned with networking.

It just seems that if my CPU is constantly checking network stuff,
when all I have is a router, then it must be slowing it down.

The communication with the router is part of networking, and so is the
result if you bypassed the router and connected directly to your cable or
DSL modem. The only difference is what it's talking to.

The fact that a processor checks a process doesn't mean that it's slowing
down the PC in any humanly detectable way.

If you want to know what the performance difference is, and I'm not
recommending this, uninstall TCP/IP and other networking components, and go
into Device Manager and disable the network adapter, disconnect the network
cable and reboot. If you find that there is any detectable performance
difference, then you likely either have a very old PC, and/or it's infected
with malware.

Is there some actual reason, other than checking logs, that you feel your PC
has slowed down? If so, what are those reasons, and what is actually
running?

Thanks Patrick. Yes, there are several manifestations of intermittent
poor performance. For example, recently I've noticed a significant
performance drop in PaintShop Pro 8. It seems to hesitate before doing
almost anything, far from brisk as it normally was. And there are
others. Not as objective as I'd like, but I definitely feel a
'hesitancy' on occasions and that's when ProcMon seems to be heaving
with this Lsass.exe stuff.
