I lost all but one of my COM ports, now I can't talk to one of my bluetooth device.

Hi Trimeric,

Open "Device Manager"
Select menu "Action" -> "Add legacy hardware", then Click "Next"
Select "Install the hardware that I manually select from a list (Advanced)" -> then click "Next"
Scroll down, then select "Ports (COM & LPT)", then click "Next"
Select "Manufacturer" as your need, (in this case, I'm selecting standard type or default option) then click "Next"
Finish!

Let me know, please. kinds Regards

Douglas, thanks for the head start on this issue.  But, something major is missing.  I've been fighting this issue for the last three days.  I even lost my image and drives.  Now with a new system reboot, I have two mirror systems.  One very bad and the other somewhat workable.  I tried your method two days ago and yes I can generate a new Comm Port.  But! Windows looks at it as failed hardware that isn't connected.  I've finally got back my USB drives; however, I've tried loading a "new" software program with lots of big money behind it.  It continues to fail.  I have removed it from the system several times.  Oh, back to the system failure.  The new drive (better said echo drive) has all of my data and software programs.

Back to the Comm Port and failures.  It all started with a Windows update around Friday (March 15, 2019) or the morning of Saturday the 16th.  I wasted my restore points and thought I was going to have to rebuild my entire system - any ideas will help.  Oh, I'm running Windows 10 Pro version 10.0.17763 Build 17763.  Thanks. LCW

Hi Douglas,

Thanks for your reply. I tried the 'Add legacy hardware' approach, it didn't work. The device manager showed new com ports being created, but they were not working, and upon looking at the properties of the newly created ports, it said windows don't know the settings for these newly created ports.

I reverted back to the previous build of Windows 10. This brought back all my com ports and I have been using them as before. This is an intermediary fix, I know, but I am pressed for time and that was a quick fix.

Thanks again for your reply, please let me know if you know some other way of handling the problem.
