Mine are legitimate too. As long as you installed it deliberately, knowing exactly what it involved, that's fine. The first release was a critical update and I doubt many users knew what it involved.
I've had problems with WGA under Vista (legitimate copies) and don't use Vista now partly because of this.
At the end of the day, I don't like being snooped on, find it inconvenient and think it's just the beginning of something more sinister.
I've seen public-facing monitors saying they're running stolen software (they weren't) and I've spent the early hours explaining that updating several computers with new disks and RAID arrays doesn't make me a pirate (I'm not.)
Soon we'll be calling MS to explain why we want to watch a film in the dining room when we watched it in the living room just yesterday. I hope not but if we all just roll over and accept these 'advantages' they'll become more intrusive.
My original post was more about MS's attempts to sneak WGA onto PCs without the user knowing.
I'm sceptical as to just how innocent WGA is (or will become) after MS used (and continues to use) such underhand methods to try to install it.
