All images are perfectly legal to use on your websites, sales pages, auction pages, within your headers, ebook and software box covers, anywhere you like! Within reason of course, I mean you're not going to be able to use a Windows or Linux image as YOUR actual LOGO, that's common sense I would hope. But you CAN use them to signify that your new software works on a Windows or Linux platform.
