Win2k updates from local drive?

I did a "nuke and pave" on a PC last week and took the opportunity
to save a copy of everything from the WUTemp folder before rebooting.

I installed 2000 slipstreamed to SP4, then all the latest hardware
drivers, DirectX 9.0c, Media Player 9 plus the codec update,
IE6 SP1*, all the stuff that's needed and available to download
normal, full installers for.

Even with all that updated, there are still 33 critical updates
to get via Windowsupdate. That's 20.4 Megabytes. PLUS a few of
the "optional" updates that're really required.

Next, I checked on my personal 2000 Pro box and it needed a
couple of critical updates, so I copied all the files into the
WUTemp folder and,,, Windowsupdate ignored them and downloaded
the two patches off the internet.

Is there a way to make Windows 2000 automatically install all these
updates from a local folder on the same PC? I've found ways to
do it from another PC setup as a server on a LAN, but I don't
have a "spare" box to do that with and I work on a lot of PCs
that don't have a NIC. I'd really like to be able to put all
these updates onto a CD-R and have a way to make Windows install
them from there.

It would certainly let me get PC's fixed up a whole lot faster
instead of sitting around for three or four hours waiting for
what needs to be Win2k SRP1** to download.

Of course I _could_ install these all manually, one at a time,
but having to reboot the PC over 30 times doesn't sound like
a whole lot of fun. Then there's the possibility that some
won't properly register, causing the Windowsupdate site to
constantly claim they aren't installed, then failing to install
them because of "old" file version mismatches. (There are a
lot of improvements that could be made in the update process.)

*I did the trick to make it download all of it for all Windows
versions, then modified the setup files to force it to use the
local files instead of going to the internet or a server on a LAN.
(I'd like to know WHY Microsoft hasn't updated the IE6SP1 download
with any of the numerous patches that've been released since! It's
long past time for IE6SP2 with all these updates incorporated.)

**I'd much rather have two or three SRP's (Security Rollup
Packages) a year, then a yearly Service Pack that combines all
the previous SRPs. MS put all the "final" updates to NT4 into
a SRP because they didn't figure there was enough to call it
SP7.
