After build 10162 I found that Windows Spotlight option is missing in the Lock Screen Settings on my desktop PC (It did appeared in build 10130 & earlier). However, the option appears on my tablet. I used the same installation image and that makes me feel very strange. Wondering if you guys are having the same issue. P.S. I've got a few guesses: Perhaps windows spotlight is only available on mobile devices or Wi-Fi is needed. But that doesn't make any sense.
