Configure Google Chrome to open .docx files in Microsoft Word instead of just downloading them
It is possible and not difficult too. First, download one .docx file. Then, from the download bar at the bottom, click on the chevron to right of the name of the downloaded .docx file. From the context menu that appears, select "Always open files of this type".
You can undo this anytime using the Settings page.
You can add the chrome official extension to do that (otherwise chrome will just download the file):
