Running Windows 8.1 Pro on a desktop.  Cannot disable Bluetooth nor wireless.  Airplane mode visible (in PC Settings > Network > Airplane Mode) but grayed out.  The toggling on/off options for Bluetooth and wireless not available.  Bluetooth and wireless both work fine (hardware is fine).  Bluetooth and/or wireless can still be disabled from device manager, there should be a on/off toggle but is not there.  What am I missing?

Please run a system file check (SFC)
All instructions are in our Wiki article below...
Should you have any questions please ask us.

System file check (SFC) Scan and Repair System Files

I ran

sfc / scannow

No errors reported

dism /online /cleanup-image /restorehealth

errors fixed

dism /online cleanup-image /checkhealth

nothing found

Any ideas?  I was checking to see if maybe a group policy object could have disabled it, but that's not it.

 What am I missing?

Please try the suggestions I made there.

Also, I recently became aware of a tool from the Windows SDK (I think that's where I got it.) called Inspect.exe  It's supposed to be used for checking UI for accessibility but obviously it gives more information about solving obscure usability issues too.  It helps to have two monitors to use it.   ; )
