After the recent Japanese landscape, and Mountain’s Glow themes, Microsoft published a new wallpaper pack – “Lake Baikal” – containing 15 images on the Store and is available to download for Windows 10. The theme description says Baikal lake that lies in the southern Siberia, Russia is the largest and deepest freshwater lake in the world.
After installing the theme, open Settings app, visit Personalization > Themes and select “Lake Baikal” to see its wallpapers on desktop. Do note the wallpaper pack doesn’t bring any audio effects to Windows 10, these are just images only.
Microsoft has added “photosensitive seizure” warning and notes the images should be used on desktop only. To install this theme, you should be using Windows 10 build 14951.0 or higher on your computer. To check Windows 10 version or the build you’re using, run the “winver” command in the Run dialog.
