How to stop IE from launching Edge on "unsupported" websites

Microsoft has released an update this month which prevents some websites from loading in Internet Explorer; instead presenting the following page saying "The website you were trying to reach doesn't work with Internet Explorer" and launching the webpage in Edge.

How can I disable this "feature"? I require Internet Explorer for some websites.

1. Open regedit
2. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Ext\CLSID
3. Find the key named {1FD49718-1D00-4B19-AF5F-070AF6D5D54C} and change its value from 1 to 0
4. Restart Internet Explorer

After some time (maybe on reboot?) this key will change back to 1 again, so you might want to put it on a Scheduled Task for on logon.
