lost bluetooth function after windows 10 Fall Creators update.

I updated my Dell tablet this morning to latest build, I immediately lost bluetooth . Not even listed in Device manager. When I ran Bluetooth trouble shoot, the result was that my Atheros Bluetooth UART Transport driver cannot Start ( code10) . I did not try to uninstall driver and restart computer . However after I rolled back to previous version of windows10 , Bluetooth started working again.

I seldom use this laptop . How do I stop windows from trying to update version again ? Tks

Previous version of Windows 10 worked well in my dell tablet. The creator's version broke the bluetooth function . I have not checked for new drivers at the Dell website.

I tried to do that yesterday. But the installation process got stuck and never completed. I rebooted and found that the bluetooth version remained unchanged. I lost bluetooth and to manually turn on bluetooth and allow discovery . The version of bluetooth at Dell website is not the same as the current one in the tablet. When I requested to update from device manager , it returned that I have the latest version already . I am going to leave it for the time being since its working fine ......until the OS wants to update to to fall creators version again

I tried that previously but did not work. In fact the bluetooth icon did not show up at all when I clicked on view all. Anyway I will try again after the next update.
