Likewise, but I only reserved this morning because I'd been lazy about windows update. You need KB3035583 and KB2952664 for Windows 7 for those of you who don't let windows update do whatever it wants. Keeping in mind you can always reserve it on any type of pirated copy, but it seems like only Daz copies are carrying over as genuine. I ended up having to run a script I found on the MS forums and manually download 3035583 to get my upgrade notification to even appear.
You can check if you'll pass and be genuine for 10 or not by opening IE and going to

You'll need to let it run it's plugin. I was able to check in Firefox after doing the process on IE.
