At least some of their developers do….
An absolute classic. I was trying to download Microsoft Media Player 10 (to reinstall it, because ONCE AGAIN, MS Windows and MS Media Management and MS PowerPoint are not all talking to each other when it comes to multimedia!!), and on the instructions page to get Windows Authentication, I saw an interesting thing… an image of the Firefox download manager.
OK, so follow me here. In order to download MS Media Player, I must authenticate that I am using genuine Microsoft software. In order to do that, I must download a plug-in. The guy who designed and tested this at Microsoft does not use Internet Explorer, however, he uses Firefox, and took a screenshot of his own download for the official Microsoft help page. Check it out here (if you can get in).
As Nuf Sed would say, “Beeooootifull”
