All apps have disappeared from start screen from my VAIO laptop. How to restore them?
There are three causes for this error:
The icons have been deleted. Try opening Recycle Bin because there is a chance they're stored in that location.
The icons have been hidden. You can bring them back by going to Computer > Tools > Folder Options > View > Show hidden system files and folders.
The option which manages this option was disabled. To enable it, right click the desktop then select View > Show desktop icons.
