About dialog

Windows Server 2016 build 14257 (rs1_release) is a build of Windows Server 2016. This build was previously only available as an install.wim containing the Datacenter Core SKU, which was shared on 28 June 2020. A full version of this build with Desktop Experience was later uploaded to the BetaArchive FTP server on 4 February 2021.

Installing Datacenter Core SKU from a WIM file[edit | edit source]

Originally, this build was shared as an x64 Datacenter Core SKU install.wim file. The Hyper-V hypervisor must be used for installation. On other hypervisors, the build will freeze at the boot screen after installation.

To install, create a blank VHD file, then partition and format it. Then, use the DISM /apply-image parameter to apply the WIM to the hard drive:

dism /apply-image /imagefile:the\path\to\the\file\install.wim /index:1 /applydir:Hard drive letter:\

After that, add the boot files:

bcdboot drive_letter:/Windows

Next, boot from the hard drive. After installation, it is required to use a password removal tool such as PCUnlocker Live CD to remove the unknown password. Then the user may set the system password and login to the system safely as well.
