OpenOffice File Association

[AHarrold]

I've installed Open Office 4.1.5 on a new laptop with Microsoft Office pre installed. During the installation it asked if I wanted to change file associations to Open Office which I selected. However on trying to open a word document it opened in MS Word. I went into Start--Settings--Apps--Default Apps--Set Defaults by App--Open Office--Manage, certain file types are set to open Open Office Calc, however the main file types, .doc, .docx etc are blank. If you try to select a default app I get what looks like a blank app, and Look for an App in the App Store, no other apps are listed to select. Back at Start--Settings--Apps, Installing Apps is set to 'Allow Apps from Anywhere'.
I've tried uninstalling Microsoft Office, reinstalling Open Office as an Administrator, and nothing I can currently do will give Open Office the default to open .doc, .docx files etc.
Laptop running Windows 10 Pro

I'm out of touch with modern versions of Windows, bu the traditional method of setting File associations is to right click on a file of the type you wish to associate, then from the popup choose "Open with" and select the file you wish to open that type. At the bottom of the window should be an "Always open with" link (words to that effect). Best to choose this.

If only things were so simple. MS have decided to go the extra mile to make things much more difficult.

I think it still works!
