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 by gus33000 on 28 June 2020.

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. You must be sure to use the Hyper-V hypervisor for installation. On other hypervisors, the build will freeze at the boot screen after installation.

1. Create blank VHD file, then partition and format it.

2. 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:\

3. Add boot files:

bcdboot the letter of the partition where the system is installed:/Windows

4. Boot from your hard drive.

5. After installation, you will not be able to login as administrator, you need to use a password removal tool such as PCUnlocker Live CD to remove unknown password. Then you can set your log in password and login to the system safely as well.
