Recently, I've upgraded from Windows 8 to Windows 8.1. Now I have Windows 8.1 x 64 SL Edition. Everything is working like charm. But I noticed that the betta fish start screen background is missing. I have seen many start screens featuring betta fish like the screenshot below;
Below is a screenshot of available start screens in my windows 8.1.
How can I get betta fish into my start screen? I don't want to add betta fish like downloading the blue fish background to my PC, and use it since it will give me no customization, and I will get just the blue fish. I want it to be customizable like other backgrounds (like changing the color)
