Where to download the lastest Windows ISO (legally)?

I have the dreamspark MS license. However, everytime I have to install Windows on my PC, I get many updates and this process is long and boring. Is there any way to download the lastest Windows ISO with updates?

I'm trying to install Windows 7 (but Windows 8 would also be helpful).

Note: I don't want just download windows. I want to download the OS with the lastest updates, those that are downloaded with Windows update after installing it!!

Thanks!

I don't believe this is legally available. However, you can make your own. The process is called slipstreaming, and there's a guide from TechRadar here. www.rt7lite.com will help you create a slipstreamed ISO, though acquiring all the updates is kind of frustrating.
