Windows 8 build 7900

Windows 8 build 7900 is a build of Windows 8. This build, along with 7867, was shown running on two NVIDIA Tegra and Qualcomm Snapdragon ARM-based SoCs at CES 2011 in Arizona, USA to demonstrate the capabilities of the then-evolving ARM32 architecture.

As this build's lab isn't working on new features, but on ARM compatibility, there are only minor changes in the user interface: the window title is centered instead of being aligned to the left, the caption buttons are slightly bigger than in Windows 7, the branding has been changed to "Microsoft Pre-Release Windows Operating System" (interestingly, unlike the later build 7871, and closer to 7875), and an IE 9 build is used instead of IE 8 RTM.

The characteristic User Tile seen in builds 7788 through Windows 8 build 7899 isn't present here or is disabled. The desktop background utilizes the one seen in the RTM build of Windows 7 in place of the blue-green gradient Milestone 1 wallpaper that was used since build 7788.
