Windows 8 Pro DSP Winter Special Campaign (DSP版 Windows 8 Pro 冬のトクトクキャンペーン)
The Windows 8 Pro DSP Winter Special Campaign Media featured Yū and Ai Madobe.
The Media consisted of two downloadable Theme Packs, each includes two wallpapers, Yū and Ai system sounds with a few differences between both Packs, and two .deskthemepack files integrating each both wallpapers and the voices of one of the two twins.
Data
It is unknown how exactly the data was originally presented, probably it was some .zip file. Even though its content was made available in subsequent Media such as the Windows 8.1 Pro DSP Release Commemorative Packs compiling data from past campaigns, the 2012 Winter Media in its original form is considered as lost with no way to access it anymore nor known verified archive.
Wallpapers
The wallpapers uploaded on the Database are .webp losslessly derived from the original .psd files found in the Windows 8.1 Pro DSP Release Commemorative Packs. Alongside the .psd were provided 3200 × 1800 or 3400 × 1900 .jpg files, though it is unknown whether these were exactly the same files from the original 2012 Winter Media.
