For several years with Windows 10 I have been using Cortana to find a file by name, and then open the file location in Explorer.
For some months now the only right-click option has been "Open in Browser".
This really bugs me, because the browser is slower for file operations (rename, etc), and I'm stuck with a browser app to open the file.
A possible factor may be that the search results are typically from a cloud location, ie. OneDrive. However they are seen as a local drive on my computer. If Cortana finds a file which is strictly on a local drive then a right-click gives me the option to "Open file location"
To investigate, I've searched for advice on Cortana, its settings and search results, and the typical advice is how to select the browser (Edge or Chrome, etc.) for the search results. The Cortana settings don't seem to have anything related to this.
How do I restore the old option to open in Explorer?
And this is what it looks like now that it's fixed:

It seems to have been a Windows 10 bug. The fix described below didn't work for long, but the problem has just gone away for a couple of months now. File search results from Cortana now give the option to open in File Explorer, it's the first option, and it works (ie. doesn't open in the browser).
