Open two Excel files in two different windows

How to open two Excel files in two different windows, at the same time and with two Excel programns opened? The task seems easy, yet by default, Windows 10 opens both files in the same software, i.e. Excel 2016. So you have to navigate between the files, but can’t see them at the same time. It is therefore useful to have two windows, or even better, two screens to compare two Excel files.

Start by opening the first file with Excel 2016

To open the first file, launch Excel 2016 and search for the file to open via File > Open > Browse.
