Windows 10: Why is my background being invaded by this blue stuff?

Sometimes when I move my mouse over my applications, they just decide to turn blue for no reason. I don't know why and I've tried to clear my cache and other stuff with my AVG software like updating my drives. Whenever I use the cursor select feature using the left or right click this weird blue stuff also appears and lingers wherever I move my selection box. Sometimes the entire screen will turn blue at once while clicking around and sometimes my cursor selection inverts and instead wherever I use cursor selection the blue background turns normal again, I have no idea why this is happening an

Unnecessary background stuff – list?


I did that a few weeks ago but it’s still slow. So, like I said, I need a list of unnecessary stuff with brief explanations. Example, I want Microsoft Edge. But I don’t have it open and it says it’s running in the background. What does that mean? If off, does that affect its function-performance………what? There is a lot of stuff like this and I don’t want to have to keep turning off, going back to check, turning on again, not remembering what I did, or did not do etc. I want to do it once and forget it.

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.
