How to update Windows in a template

This is the documentation for the deprecated product DCImanager 5. It is no longer updated and may be irrelevant. Documentation for the current version of DCImanager can be found in the DCImanager 6 section.

To update Windows in the OS template:

Connect to the server that runs Windows with the Admin permissions.
Download the OS image from the ISPsystem repository.
Extract the files to C:\win_update\win_template.
Download updates from the official website and locate them to C:\win_update\updates.

Open powershell and enter the commands one by one:

mkdir c:\win_update\wim

cd c:\win_update

DISM /Mount-Wim /WimFile:win_template\win2019\sources\install.wim /index:2 /Mountdir:wim

DISM /image:wim /Add-Package /Packagepath:updates

DISM /Unmount-Wim /Mountdir:wim /commit

Zip the updated file C:\win_template\win2019\sources\install.wim into the archive with the OS image.
Add the OS image into the storage and check its installation on the server.
