This is a Microsoft ad. It doesn't have any computers in it, or any software, or peripherals, browsers, web portals, or servers. The most Microsofty thing in it is a former employee. That, and the ad makes no sense. So, Why?
My best guess is that MS considers the Vista problem a problem of image more than substance. When the "Project Mojave" ads - secretly switching your detergent with a mystery operating system that didn't suck and turned out to be Vista - failed, they decided they need to trot out the one thing about MS people do seem to like - Bill Gates.
