File Explorer Edit Icon

I'm looking for the way to get the 'edit' icon to work again on the ribbon of File Explorer (on the Home tab).
Before I got my new computer, I was able to highlight an html file and then click on the Edit button and SharePoint Designer would open.
However, I can't get it to work now and I don't know why.
I have:
1) Gone to Internet Options > Programs
It's set for SharePoint Designer to be the default editor
2) Gone into SharePoint Designer > Tools > Application Options
It's set to be the default editor
3) Gone to Settings > Default Apps > Choose default apps by file type
But I don't want SPD to be the default to open it, just edit it.
4) Gone to Settings > Default Apps > Choose default app by protocol
Again, I don't want SPD to be the default to open it, just edit it
5) Gone to Settings > Default Apps > Set defaults by app
SPD is not listed in there and if I look at the IE (I don't use Edge), it's set for default for opening everything and not option in there for changing the app for editing an html file

I'm stumped. Where else IS there to go so the Edit icon will be usable and open SPD?

 

What Operating System? (Win 7, 8.1, or 10)

 

I'd guess at W10.

 

Oops...forgot that. Yes, Win10 with all updates.
