SvcHost.exe (NetSvcs) using up tons of RAM

Here's a screen cap of my Resource Monitor screen on my laptop with Win
7 64-bit HomePrem:

As you can see SvcHost.exe (Netsvcs) is using over 2.2 GB in the Commit
memory and over 1.5 GB in Working Set memory. And there at least 3 other
processes over 250 MB, combining with it to use up about 70% of the 8 GB
of RAM on this laptop. What could be causing this much memory to be
used, mainly by Netsvcs?

As administrator, you can put wuauserv (part of Windows Update)
into its own svchost. Then, when it goes nuts, there is only the
one service inside that SVCHOST and you know for sure it is the
root cause.

sc config wuauserv type= own

You can apply this update. It reduces RAM consumption by
wuauserv. But, it does not fix the root cause, which is
unbounded CPU usage during "supersedes calculations".
You might find one core of the CPU is busy for half an hour.

The same wuauserv problem existed on WinXP as well.
Microsoft just doesn't want to fix it.

On Windows 7, you can try installing "the highest version of
Internet Explorer", followed by "cumulative update for
IE for the month of September". In other words, patch IE
as high as it will go. That will reduce the CPU consumption
when Windows Update runs. Instead of half an hour, it might
run for ten minutes instead.

svchost.exe is used to roll multiple services under one process. To see
what processes have been rolled into an instance of svchost.exe, use
SysInternals' Process Explorer. Right-click on a svchost.exe, select
Properties, look under Services tab. Alternatively, for a terse list,
just hover the mouse over a svchost.exe process to see the popup that
lists the mashed together services. Might clue the culprit service.
