LOL sooz. I didn't have the "gear" icon. I had nothing, no fave star, no home page button. Just this page showing. I couldn't close it because I also had no "x" and no address bar.
I DID actually make sure the items were unchecked and even checked the box that says "do not suggest, blah, blah" but it would not let me apply that, so I just hit cancel with the boxes unchecked. It still applied it.
I finally got my control panel to load and made the switch to my Google homepage. Had to disable my antivirus to do the restore and then, guess what? Windows update was still sitting there when I came to work. I'll see when I get home, but I'm pretty sure the update didn't do this because it worked fine for hours afterwards yesterday and this morning for a while.
For all I know, I hit a key that does that............

With my work laptop, I am always accidentally hitting keys that do funky stuff when I'm trying to type. roflmao! My little fingers, that are slightly deformed (missing the lower knuckle, a genetic anomaly) have a mind of their own sometimes.
