I'm experiencing the same problem. Haven't resolved it on my computer yet. Win 8.1, not in Homegroup, not in Domain, etc. etc., like most of you, not running Hyper-V (though it is a possibility and is installed, I frankly have no idea what the heck it IS
much less how to START or USE it), but also, ...
I have no "NwCategoryWizard" entry in the registry anywhere. It's not a key or a value or anything else. The sub-folder under
*HKCU\Software\Microsoft\Windows NT\CurrentVersion\Network* is a folder named
Location Awareness. This folder has only the default-key in it, with no value set. A full search of the registry for the string "NwCategoryWizard" finds nothing.
Harrumph.
I'm interested in finding a resolution to this problem (lacking the "Find Devices and Content" slider, and all the associated corruptions which its absence implies) simply to TURN ON MY DANG BLUETOOTH ANTENNA.
I had hoped maybe I could click my way through THIS solution as a step toward THAT solution. But I'm getting nowhere. The computer is still under warranty at HP, but the only service they've offered is that they'll let me ship it to them so that they can
restore to factory-condition settings etc., which might as well be an admission that "we have no bleeping idea, and neither does Microsoft."
Keep this thread going, maybe someone will find a solution?
