What was claimed? Well, some guy decided that he wanted to crack his (legally purchased, no doubt) copy of Photoshop on his Windows 7 install. Windows 7 then sprung into life to break his crack, defend Photoshop's virtue against his unwelcome advances, protect a load of random DLLs from deletion, and open up the firewall so that Adobe could see that he was up to no good. Yup yup. To add insult to injury, Windows 7 then crippled the dude's sound card. Or something. As is so often the case with this kind of story, the truth is more prosaic.
