PPRuNe Pop, as one who's just had their staples out I hope you're feeling okay. I suspect yours was a tad more serious than my lumbar issues.
Belarc, and their nice team could not find the Key that was imbedded in my Asus super-shard. And they/we really tried.
The Key symbol on the bottom of the kit showed just the Windows end of the usual strip. It had not been cut, that's how it came.
Right now I wouldn't buy anything that does not declare the Key loud and clear. Finally, on my third bounce between Asus and MS, the latter sold me a full and free 8.1 for $45. A fair compromise.
