I'm looking for more information about customizing Surface Collage that came preloaded on a Sony Vaio L Series. Specifically if there is a way to change the default background. I have searched for any support for this software but I haven't found any.

Hi, It appears that the question is related to Microsoft Surface, since we have specific support for this, it is recommended that you contact Microsoft Surface Support for help: Microsoft Surface Support Options Thanks.Nicholas Li - MSFT
