Windows Update using over a GB of RAM constantly

Very strange. I don't have 3083324. It's not in my hide list or my don't install list.
Plus it not offered.

It's not in my hidden list or list of updates to avoid either. It showed up as "important" - not sure why it's not offered to everyone.

EDIT: Okay it has now made it's way onto my list of updates to avoid and I've removed it.

I haven't seen KB3083324 yet not on 9/3... or today
Of course I haven't been offered any updates yet though :)

I have fixed this (two different PCs) by manually installing June 2015 Update Agent. As far as I can remember, I had to stop BITS in order to install it.

I downloaded KB3075851 using my browser.

My 1st attempt to install KB3075851 failed.

Once I stopped the BITS and WUA services, KB3075851 installed.
It instantly fixed the RAM and CPU issues (mostly).
There is still a bit of CPU churn (25%) but RAM usage has dropped from 2GB+ to ~200MB.

It still (apparently) took over 2 hours to generate the update list.
When I tried to install a few updates my VM behaved normally.

After a few minutes it had downloaded them and after another few minutes they were installed.

WU may be working now so a bit of CPU and mem is expected until updates are done for. On my machines CPU and mem dropped to normal values.

Agreed.
If there are still updates to be installed (not including Hidden or Optional) it will keep using CPU power. :)

Once all of the updates (not including Hidden or Optional) were installed, the CPU usage dropped to 0 and the RAM usage dropped to ~20 MB (a significant improvement on 2GB+).

A weird thing I've noticed is that once I click "Install updates", it takes a certain amount of time before it actually starts downloading them.
The time seems to be equal to ~0.8 minutes per update selected (on my PC).

I selected today's 11 updates and it took ~9 minutes before WU actually started downloading anything.
Last night, my VM took ~16 minutes to start downloading 20 updates.
The 3 updates before those took ~2 minutes to start.

TrustedInstaller does an integrity check on all downloaded files, correlates results, and works out the order of install, before allowing the install of the first update.

Did you mean "... does an integrity check on all system files, ..."?

I meant before WU starts to download the chosen updates.
That is to say, no network activity is detected until after the mysterious delay.

After the update downloads have finished, there is almost no delay before the installation begins (on my PC).

It must be a VM "thing".
My "real" W7 install only suffers a delay of a few seconds per update (before downloading begins).

I don't believe my "real" W7 is 20x faster than my W7 VMs (since I notice no performance differences apart from boot time).

I have to say I have never noticed this Note at the bottom of the settings page :/
