How to disable the lock keys notification? Acer Aspire 4738

Sorry for the late reply, my internet has been messing up...

Anyway, all you have to do is to go to the Launch Manager folder in program files and there is a folder name CloseApp, inside that folder, just run CloseHookApp.exe and everything will still work fine and the notifications will be gone. If you want to keep the notifications disabled just set you computer to run the exe at startup, I would recommend putting it on a delayed start as this method will only work AFTER launch manager has started.

Look for Launch Manager.
Right click icon then 'Open Containing Folder'.
(Should be c:\Program Files(x86)\LaunchManager)
Open subfolder 'OSDRC'.
Delete the files CapsLock_On.png and CapsLock_Off.png (or move them elsewhere).
You can do the same for any of the other icons that are troublesome.
