On Windows 10, the Calculator app has a new “Always on Top” mode, which allows you to keep the app always visible, and it’s a handy feature when working with multiple windows, such as Excel spreadsheets and shopping online.
How to enable ‘Always on Top’ for Calculator app
Use these steps to enable or disable the “Always on Top” feature on Calculator:
Open Start on Windows 10.
Search for Calculator and select the top result to open the app.
Click the menu button from the top-left and select the Standard option.Quick tip: The Always on Top feature is only available for the standard calculator mode.
Click the Always on Top (Keep on top) button, next to “Standard,” to turn on the feature. (Click the same button again to turn off the feature.)
Once you complete the steps, you’ll see a new compact version of the Calculator app that always stays visible no matter how many applications and windows you’re currently working on.
