Multiple instances of "Internet Explorer" and Internet Explorer (32)"

On my Win10 x64 home computer, I find that a I can't always start Internet Explorer (ver 11). I'll click on the icon, the "working" symbol spins for a second and nothing happens.

Then I open Task Manager, and I find about 10 or 12 instances of Internet Explorer and IE (32) running/open. If I then "End task" for each one. I can then get Internet Explorer working again.

For some reason IE is not closing fully when I end the session. It appears that I can continue opening/using IE until I get about 10 or 12 instances running then I can't open or use IE again until I close of all the open IE processes in task manger.

Has anyone else seen this? Any idea what might be causing it?

Hi,
1. Try IE in safe mode:
Run Internet Explorer in Safe Mode (without Add-ons)

- use Option 2.

If that works ok, selectively enable add-ons in IE11 and see if you can find out what's causing the problem.
Post the result.

If it doesn't, proceed with this:

2. Try 'uninstalling' IE and reinstalling it.

Windows key + X, click Control Panel
Click Programs and Features
Click Turn Windows Features On or Off
Untick IE 11
Restart
Now reverse this - and tick IE 11.
Restart
Try starting IE11 and post the result.
