Getting a new PC soon. Is there any way to speed up the update/install process?

So long story short I'm getting a new PC and I usually format it and install a clean copy of windows to remove all of the crapware.

It's been 6 years since I last did this. I have a license for Win 7 Ultimate 64-bit.

Are there any projects around that maintain slip-streamed ISOs with all of the latest updates?

I know about Ninite. Is there anything else I should be aware of?
