Windows 8 build 7878

Windows 8 build 7878 is a build of Windows 8. Seven screenshots of this build were shared in a folder included with build 7746 on 3 May 2020. It was later shared on the BetaWiki Discord server on 4 June 2021.

This build already showcases significant evolution from 7875. The M2 metro OOBE has been introduced, as well as the new AutoPlay (although it is simply a height change at this point).

Finally, similarly to build 7867, it uses the Arial font for the title bar and watermark.
