Windows 8 build 7867

Windows 8 build 7867 is an internal build of Windows 8. This build, along with 7900, was shown running on two NVIDIA Tegra and Qualcomm Snapdragon ARM-based SoCs at CES 2011 in Las Vegas, Nevada, 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 and the kernel version number has been changed to version 6.2. It is the earliest known build to make use of an invalid font for both the window caption and watermark, which both point towards Segoe UI Semilight, resulting in the font falling back to Arial. The issue would persist up until build 7901 (client) and build 7904 (server).

A low-quality camera recording of the build itself, which showed the Paint application running on the aforementioned Snapdragon SoC and revealed the full build tag, was later uploaded by former Windows division president Steven Sinofsky on 30 October 2022 along with video footage of builds 7792 and 8090 in issue 104 of their account of events during his time at Microsoft, titled Hardcore Software.

CES 2011 demo differences
Various aspects of this build were either changed or disabled during the CES 2011 demonstration, two of which are likely a result of file replacement originating from newer builds:
 * The characteristic User Tile seen in builds 7788 through 7850 is not present or was disabled.
 * The branding observed within the watermark was temporarily changed to "Microsoft Pre-release Windows Operating System", in a stark contrast to the older Windows 7 branding commonly seen in builds such as 7779 and 7850.
 * The desktop background was changed to 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 (server); although the footage uploaded by Steven Sinofsky depicts the build itself utilizing the latter as the default.
