After upgrading to Windows 8.1, users have came around various issues in the last few weeks. Like the one problem we’ve recently shared here, there are many other questions unsolved. We have just came around the issue of failing Bluetooth drivers after upgrading to Windows 8.1. The problem was actually the failure of driver to initiate the Bluetooth service. When we checked the driver properties, we got:
Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)
As you can see in the image above, there is clearly mentioned that something is wrong with the registry entries for the driver, thus we should correct it to solve the issue. Here is how to:
FIX : Bluetooth Drivers No Longer Working After Upgrading To Windows 8.1 Using REGEDIT
1. Press + R and put regedit in Run dialog box to open Registry Editor (if you’re not familiar with Registry Editor, then click here). Click OK.
2. Navigate here:
3. In the right pane of this location, look for the multi-string registry strings (REG_MULTI_SZ) named UpperFilters, LowerFilters, UpperFilters.bak, LowerFilters.bak. If you find any one of these strings like (UpperFilters), the one I have highlighted in the above image, right click on it and select Delete.
4. Now close the Registry Editor and reboot to get results, you’ll find that the problem is solved already:
Hope you find the fix useful!
