My Office apps have taken control over my Office 2007

[BTJ]

Hi



I have a new win 10 PC which was delivered with an app called "my office". Consisting of outlook, one drive, word, excel, PP, and more. I only use the outlook. Then I have MS Office 2007 installed and from that I use word, excel etc. BUT every time I from win explore will open a document it will open in a "My Office" app. BUT I will only use my 2007 Office. Also when I use "open with word 2007" the "my Office word" open. How to stop "My Offices" word, excel etc to open?
