I've had this problem on two different Windows PCs now, both running Windows 10 Pro: I run/enable Across Center I look at Device Manager, and find "my Intel(R) Wireless Bluetooth(R)" device is disabled. If I open properties, I find the device status is: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)" I've already followed advice in these forums for switching back to the Microsoft Bluetooth stack. I've been unable to do so. I uninstalled Intel Bluetooth drivers from Programs and Features. I deleted the Intel Bluetooth service from my services using sc delete. I even temporarily disabled Windows File Protection/System File Checker (!) and deleted all files I could find named ibt*.* under C:\Windows . Still, these files come back after a reboot, and Windows insists on using Intel Wireless Bluetooth. I tried following instructions in your FAQ for selecting the Microsoft Bluetooth stack, but without success (there is no "Generic Bluetooth Adapter" option available to me when I choose "Let me pick from a list of available drivers on my computer"). At this point, I don't see what more I can do without putting the integrity of my PC at risk. Any suggestions are appreciated.
