I am borrowing a friends laptop and have my own version of windows 7 installed. Now I am returning it and want to uninstall the os. My friend will install his own operating system at some point. I want to return basically an empty computer. How do I uninstall windows 7 and completely empty the computer without replacing the os or reverting to a previous os or something?
As a follow up question: Don't you only have a few installs of windows 7 using one key? Is it possible to do something like deactivate the product key on that laptop or something? I'm not really sure how this system works. Thanks for all your answers to the previous question
