Hello Doc Brown, and welcome to Seven Forums.
Answers inline. :)
Scenario:
I've taken a base Win 7 install iso, then created a slipstreamed iso which includes SP1 and many updates. When I install this in Virtual Box, it installs perfectly. But I find I missed a few updates so WU asks me to install these. Fine so far. Question: What is the correct process to create a new iso that includes these missed updates and possibly future updates? I tried starting with the iso I created but I can't seem to get the new updates to be incorporated.
You should normall be able to add new updates by using steps 5, 7, 12, 12G, and 15 when doing the tutorial. What is it doing or telling you when you try to add updates?
I'm wondering because if I want to create a newer iso as time goes by, do I need to keep all the update files that I downloaded. That's a bit of disk space to hold on to, almost 20 GBytes at the moment.
If you have the HDD space, then keeping all of the MSU files for the Windows Updates would be the safest thing to do in case you ever needed to start over, or just wanted to create a new ISO with them. This way you do not risk having to download them again.
I don't really see this answered. It's stated that you can't do an repair update from the slipstreamed Win7 w/SP1. Is it known why that's the case? Assuming that I created an iso that had exactly all the latest updates and matched what's installed on my system at the moment, it seems that the version should be the same. Why does Windows reject that as a valid repair update candidate?
Something about the process that is used to create the slipstream disc just makes it unusable to use to do a repair install with. I don't know the exact reasons for why though.
When you have many updates, does the order you specify them matter? If so, how would we know the proper order? Some of the missed updates are much older. (I apparently didn't go back to a far enough date in my selection process.)
For the best results, they should be included in the same order that they would have been installed in Windows Updates. You would just go by the "Date Installed" and the order listed in
View update history and in
Installed Updates.
As I was trying to figure out how to get 100+ updates I found that if I go to the Windows Update Catalog, I could search and filter and, assuming I selected all the ones I needed, download them all in one swoop. Saved a bunch of time!! You can find it by searching on Windows Update Catalog. Maybe it's been mentioned before, but didn't see it in this thread.
Yeah, that's the fun part there is to make sure you have the correct ones selected.
Hope this helps,
