Are you referring to this? I'm going to try this now next time I install Windows and see how it works out.
Edit: This looks like gold to me, but that could just be the long days and inability to really comprehend new material at the moment fully.
Edit2: This looks like it has the ability to create a SlipSteam ISO as well. Some one correct me if I am wrong?
It will create a limited slip stream ISO. My experience with this product is that it does a far from complete job of gathering updates but enough to allow you to finish the updating process manually with Windows update online. It fixes the bokenness of the Windows update but doesn't find and install the remainder of the updates. The slipstream ISO will contain only the updates tat WSUS gathers. It stores it in a folder called ISO. I haven't actually tried this but I noticed the folder.
If this really does what I think it does I will be so happy.
Sorry habbajabba - this is actually in your MajorGeeks link at the bottom. I should have read into it more!
Edit3: Man, my memory is shot! You posted about this really early on and I missed it somehow.
