I was wondering since the VAIO button settings can be modified through the control center, is there any way to make it into a desktop shortcut, similar to the button on the bottom right corner on windows 7? If so how?
Open Vaio Control Center and under the button options select ‘Launch Application’ > Click ‘Settings’ > and navigate to Desktop > to the right of ‘File name’ select ‘All files’ from the drop down menu > Click on the ‘Show Desktop’ icon > Click Open then click OK and Apply.
If that fails to work you may first need to manually create a taskbar shortcut. Have a look at the following link for details of how to do this.
