Steps to using Windows 10 'Open with':
In this example, we would like Windows to open our file in the Excel application:
- Right-click over the file you wish to open
- Choose Open with
- Choose Choose another app
- Scroll down and see More options
The Windows Explorer screen will pop up showing your files. Depending on how the program browses, below is the usual location of the Excel.exe but the file path may vary:
C:\Program Files\Microsoft Office\root\Office16\
- Locate and select Excel.exe
- Click Open.
Your Excel application will now be available using a right-click and the menu option “open with...”.
Note: If you wish this app to always open it select the Always button.
