Here is how I made the AR3012 working again on Windows 10 20H1.

  1. remove AR3012 & its drivers completely from 20H1, later let 20H1 detect it as Generic Bluetooth Radio.
  2. download Qualcomm driver v10.0.1.15 from Microsoft Catalog website, install this driver via driver upgrade.
  3. after v10.0.1.15 being installed, you might see additional device named in "Bluetooth LE" as the one in the Kirill's figure.
  4. try to connect any BT device you couldn't connect after upgrading to 20H1, make sure the AR3012 really WORKS.
  5. then download any Qualcomm driver v10.0.3.x (as Kirill mentioned, the newest one is v10.0.3.22, or let Windows Update do it later), upgrade  the driver of AR3012 again with this one.

Notice: NEVER uninstall the v10.0.1.15 while/after upgrading to v10.0.3.x, or the AR3012 will fail again after reboot.

Microsoft Generic Bluetooth Driver -> Qualcomm BT driver v10.0.1.15 -> Qualcomm BT driver v10.0.3.x,

if you did followed the steps, your AR3012 should be working as usual, even after reboot. 

Qualcomm Atheros Communications - Bluetooth - 10.0.1.15 (x64)

Qualcomm Atheros Communications - Bluetooth - 10.0.3.22 (x64)

I guess the "Bluetooth LE" is the critical point of this issue.

(I DID hate the crappy W10...... what's M$ doing now? let users recall how windows unstable in 1990s? )

NOTE by MELERIX: by the way, as it is an older driver, it does not support the new Windows 10 shutdown mode called fast startup*, so every time you shut down Windows and then restart it, the device appears with an error, so you have to* disable the fast startup of Windows 10*, in the power options of the control panel.*

    Hello, had the same problem and found fix: find and install manually ar3012 driver ver 10.0.1.0 (21.05.2015)

    I've tried driver 10.0.3.18 and 10.0.3.22 - they don't work in current windows 10.

    I'm glad that step helped, then. Let me know if there's anything else.

    Also when ready please mark the post which helped most as the Answer, to help others. A decent rating is also appreciated, to replace the bad rating I was given earlier.

    I have even been in the command prompt and used the DISM checks.

    I have contacted Qualcomm direct regarding this matter and they say I have the most up to date driver installed.

    I think I may have to get a plug in bluetooth adapter as none of my bluetooth devices connect to the PC but they all connect to the laptops.

    Thank you for your time

    Are you aware that the blue links are illustrated tutorials which themselves have dozens of steps included, making the total number of steps I gave you way more than could have even read in the six minutes it took you to rate my post unhelpful. So how would you know if you'd tried 50-60 steps total included?

    I'm still willing to help you if you'll go through the steps I gave and report back results for each step. The steps are sequenced so they may work better in the order I gave.
