Over the years, I have gained the desire to revert my computer to factory settings, or rather to the state of a brand new computer with a freshly installed OS. The only problem is that my computer doesn't have any of the convenient services that allow a factory reset to happen internally and requires the disk. The other only problem is that when I bought my computer it was booted with Vista and had a sticker on it that said I could download Win7 for free since it was coming out in a few months, so I have no disk. I have a product code (on the bottom of my laptop on a sticker) but I believe that is just for Vista. How can I revert my computer to "factory" Win7 settings without buying the installation disk?
