@jaxx0rr said in Does anyone know how to remove this annoying "red O" Opera icon from my system tray? It's driving me nuts.:
@itsmeray @donq both of your methods will not prevent it from starting again once its somehow reinstalled ... my method works 100%
I also took a look at the Start Up tab in the task manager and after you delete that registry key and reboot the opera app we're all hating on isn't even available to disable. Now that I've looked I can say with assurance that you did something wrong or you didn't open the registry editor as instructed. If you don't run it as Administrator and aren't logged in to Windows 10 with an account with Admin privileges my guess is the fix will fail. I would not advise as donq suggested that you delete it. I'm thinking I may want to take a look at it someday. I just don't want it running all the time and sucking up resources. Most of my Windows machines are virtual so resources are at a premium.
