Windows – AMD vision engine control center missing options

This is a common problem with default settings of Catalyst Control Center. To fix:

• open Catalyst Control Center
• go to My Digital Flat-Panels
• choose Scaling Options
• slide the slider all the way to the right (so that it is a 0%)

I figured out that the application responsible for these two icons is a background service called "VAIO Event Service", which is started with Windows. It's generally not a good idea to stop this service, because in doing so, various shortcut keys stop working. The service description also mentions that power management is disabled.

Simply put: the icons cannot be disabled without losing some functionality of your VAIO notebook.

It may nevertheless be insightful to share how I figured out which app was responsible for the icons:

1. Firstly, to get some more information about the application responsible for the tray icons, I expanded the notification area and clicked "Customize..." to open the Windows Notification Area Icons window. From there, I determined that the application name is "VAIO Control Center".
2. I then used Sysinternal's Process Explorer to review all running tasks that contain that application in the description column. Sure enough, there was a match. In the mouse-over tooltip, the match revealed that it was associated with a service.
3. In the Windows Services window, I located that service and stopped it. The icons immediately disappeared from my tray, but I could no longer disable the touchpad with the Fn+F1 shortcut.
