Try our Computer Help forum. I'm locking this one.
By the way, the second hit in google told me all I wanted to know. If you had posted in the other forum, I woudl have told you. Did you know also, that many dll's have this information in their file properties (but, I agree, not all, so it could well be that this one hasn't). Did you try?
All I can find anywhere online is that this is a dll (one of the more useful answers, by the way), and you can download it; or conversely it's not a Good Thing and you should get rid of it. It's been on my computer for ten years, and there seems to be utterly no info about what this DLL IS, what it does, or if the screen might go dark if I delete it.
