How to Apps Run in a Window

• Windows 10 apps have permission to run in the background so they can update their live titled, fetch new data and receive notification. You can resize and move around, and they have titles bars at the top so you can maximize, minimize and close with a click. 
• Click the app's option button to do basic things like search, share, print or change settings . Select App Commands from the drop-down menu for even more option; the option you see will vary by app.
