Do i need to start from the original disc? Do i ISO it or turn it into a wim?

This is going to be a stupid question, Is there any sort of guide for this? A beginners guide to it all? I've messed around with RT7 a long time ago and from what i understand W7T is the go to version at the moment, However i'm totally lost as to what on earth i should be doing. My goal was just to create a new image of windows 7 with all the updates applied and maybe a few tweaks here and there. Nothing to insane at all. Thanks
