Background applications

Hi Robert,

We understand that you don't want some apps to run on the background of your computer. What we suggest is to
control which apps are allowed to run in the background. To see which apps have permission, just follow the below steps:

• Open the Start menu or Start screen and select “Settings.”
• Click or tap the “Privacy” icon in the Settings.
• Scroll down to the bottom of the list and select “Background apps.”
  
• You’ll see a list of apps that have permission to run in the background with an “On/Off” toggle.

Just bear in mind that, apps normally run in the background to update their live tiles, download new data, and receive notifications. If you want an app to continue performing these functions, you should allow it to continue running in
the background.

Feel free to update us with the results.
