Windows 7: How do I make a Windows 7 OS Disc?

I got a new computer with Windows 7 installed on it. I like to occasionally format my hard drive and start from scratch. Before I have anything else on the hard drive, I'd like to create a Windows 7 installation disc. I've read a bunch of the threads on this site and although many are close, none seem to match exactly what I want. I tried going through Control Panel but it was going to be 33GB for a system image - that's not what I want. Just a disc with Windows 7 installation so that I can format the hard drive.

Thank you.

You have an oem pre install.

Grab an installation iso from My Digital Life

I don't understand what is in those links, but thank you for the reply. What I'm looking for is 1 disc that I put in the drive, restart the computer, then reformat and re-install windows. Again, thanks for the reply - I was beginning to think I was the only one who could see the message.

Go to the link SIW posted, download the iso you want, then use ImgBurn to burn it to a dvd.

Clean Reinstall - Factory OEM Windows 7

Thank you. That appears to be what I was looking for. 7 hours seems quite excessive for a download time but I've been begging for the last hour so I won't be a chooser now. Thank you for the help (both).
