Let's face it here, if a person is running Windows, they aren't going to believe that there's a problem until they can't work 'cause Windows gives alert after alert after alert and how can you know which ones to believe unless you're a "techie"? Sure if, you're reading here, you'll know, but 98% of people just don't.
If you're reading here there's a good chance your aren't running Windows and just came for the Schadenfreude.
