Should I restart after updating my system?
Should I restart my PC every time it gets updated?
You do not have to restart your computer every time you update. Certain updates (such as those that affect your operating system kernel) will require rebooting to take effect. When such an update occurs, your session icon in the upper-right will glow red.
You only need to restart when the update manager tells you to. It will also be visible in the menu on the top right of your screen. The cog will be red and a red menu item will ask you to restart.
