Slipstreaming updates into a Windows 7 SP1 ISO

[Charlie]

I want to slipstream all the post SP1 Windows 7 updates into one ultimate ISO so when I reinstall Windows I won't have to update for like 2/3 hours. There use to be programs that would do this, but alot have gone or the download links no longer exist, does anyone know a way, even if it's manual I don't care.

If anyone has even the slightest idea of how to do this manually or knows of a new program that does this I would be happy.

I'm assuming the most time consuming part of updating is downloading the files? If that's the case you could just download all of the updates and burn them to a DVD so that you don't have to wait for them to download and you can just install them immediately. On the other hand if you're looking to compile all of the updates into one file so that you can just install them that way i'm not sutre how you would do that.
