I had windows 7 preinstalled on my computer. I stupidly went and installed windows 8 consumer preview OVER windows 7. I made a bad decision and now.... I feel so unprofessional (probably because I am) please help!

If you know someone who has a Windows DVD that is the same version as was on your computer you can use that to re-install Windows 7 and activate it with the product key on your computer's COA label.
You can also download an official Windows 7 ISO, which you then burn to a blank DVD and use it to install Windows - once again using your COA product key to activate the system.
