Windows 10 build 14357.1000

Windows 10 build 14357.1000 is a build of Windows 10 Anniversary Update, which was uploaded to BetaArchive on 14 May 2020 only in the x64 architecture in the Italian language. This build is notable for being one of the few available Windows 10 builds to be available as an unstaged installation media, meaning all client editions available in the Windows 10 source (albeit labeled as Longhorn) are available for the user to pick from and install during setup.

Editions and keys
The following SKUs are installable in this build:

Installation
Due to a bug with the  file, the system may trigger a   bugcheck when booting to Windows Setup. It can be bypassed by debugging the file with Windows Debuggers during the installation process.

Detailed instruction:
 * A: Extract the BCD file from the installation media (located in  for legacy BIOS boot, or in   for UEFI boot) and put the file into any folders.
 * B: Open Command Prompt with elevated privileges and execute the following commands:


 * C: Overwrite the original BCD file in the installation media with the modified one.
 * D: (Skip this step if Windows is installed on a real machine) Set up the serial port for the virtual machine.
 * For VMware Workstation on Windows host: Add a serial port via the "Add..." button, change the connection type to "Use named pipe", enter the pipe's name (Format:, e.g.  ), then choose "This end is the Server, The other end is an application".
 * For VirtualBox on Windows host: Check "Enable Serial Port" in the "Serial Ports" section, select "Host Pipe", uncheck "Connect to existing pipe/socket", and enter the pipe's name (Format: ).
 * For Hyper-V: execute the following commands in PowerShell:


 * E: Install Windows Debuggers from the SDK (Windows Debuggers Preview in the Microsoft Store won't work).
 * F: Open Command Prompt, change the current working directory to the path where Windows Debuggers is installed (for example in ), and execute the following command:


 * G: Boot the machine from the patched installation media.
 * H: In debugger's command window, press Ctrl to enable verbose mode. When the final force-unload event occurs, quickly press Ctrl or select Break in the Debug menu, then execute the following commands:


 * I: When  hits a breakpoint, execute the following commands:


 * J: Install the system as normal and shutdown the machine before Windows Setup is attempting to reboot the system.
 * K: Repeat steps A and B for the BCD file on the system partition before turning on the machine again.
 * Repeat steps F, H, and I whenever the system is getting into the boot screen.

Alternatively, replacing  and its corresponding catalog file can also bypass the bug.

Miscellaneous

 * Some SKUs, such as Pro with Media Center and Embedded Industry, have Windows 8.1 or Windows Embedded 8.1 branding on the watermark and  banner as they're being retired with the release of Windows 10.
 * CoreARM (Windows RT 8.1) SKU is installable on all machines in the x86 or x86-64 architectures, though the branding is simply named "Windows 10".
 * In ProfessionalS and EnterpriseS SKUs (including its N and Eval variants), the out of box experience will restart automatically when creating a new account. It can be bypassed by pressing Ctrl to reboot Windows into Sysprep audit mode.
 * As a result of bypassing the OOBE, several user interface elements (such as Start menu and Action Center) will be broken.
 * Most of built-in UWP apps (except for Connect, Cortana and Microsoft Edge) are missing.
 * Several pages in Settings app are broken:
 * Camera, Microphone and other subpages under Privacy page in all SKUs except Team SKU.
 * The main Windows Update page in ProfessionalS and EnterpriseS SKUs, including its N and Eval variants.
