Windows 10 build 16212 (rs_edge_case) is an internal build of the Windows 10 Fall Creators Update. It was unintentionally distributed to desktop users irrespective of their enrollment into the Windows Insider Program on 1 June 2017,[1] along with a Windows 10 Creators Update post-RTM build from the rs2_release_svc_d development branch, and five days before its rs_prerelease compile.
Three separate mobile compiles from the rs_devices, rs_iot and rs_xbox branches were also unintentionally pushed out to all audiences on the same day.[1][2][3]
Hidden features[edit | edit source]
Control Center[edit | edit source]
This build, just like other internal builds, contains a control center, that can be activated by enabling the velocity ID 1195122 using the mach2 tool. As with other builds, activating the Control Center causes the Action Center to no longer display quick action buttons.

Cortana in system tray[edit | edit source]
Just like other internal builds, it is also possible to move Cortana to the system tray area by enabling the velocity ID 11314742 with mach2. Unlike other builds, this build contains a toggle that allows the user to switch between "SDK" and "RAF", which will change the style of Cortana's output.
