Like every other version of Windows, Microsoft has created a special desktop wallpaper for Windows 10. While Microsoft opted for daisies in Windows 8 and an aurora in Windows Vista, the default Windows 10 wallpaper uses a Windows logo just like Windows 7 did. It's not just any old logo, either. Microsoft travelled to a San Francisco studio to build two installations to create the Windows logo out of light. The software company used camera mapping techniques, lasers, and projectors to create the new hero image that will be used on millions of PCs that ship with Windows 10.
The result is a dark and misty logo with light that beams out and around the edges of the famous Windows logo. It matches the dark theme of Windows 10 well, but it appears the wallpaper won't be animated so the full effect (shown in Microsoft's video) won't be available on your desktop. This new wallpaper will start appearing on desktops once Windows 10 ships on July 29th next month.
