Windows 10 build 11103 (rs1)

Windows 10 build 11103 (rs1) is a build of Windows 10 Anniversary Update. This build was leaked in both the x86 and x64 architectures only in the Enterprise SKU.

Setup
Due to bugs in this build, you'll have to copy all .dll and .exe files from the sources folder of the ISO to X:\sources, otherwise setup will complain about install.wim being corrupted and you will not be able to boot. This can be done by opening Command Prompt via Shift+F10 and typing both xcopy  and then doing the same but replacing *.dll with *.exe.
