Custom OS Template (Windows)

An organisation administrator can create a customised OS template for spinning up remote desktops – it’s also a handy way to activate your own licence on the operating system.

Follow the steps below carefully; they’re essential for building a working image.

Important:

About Disk Partition
1. A customised template needs either a single disk partition or two partitions: one EFI/Boot partition and a second for system and data.
2. LVM partitions aren’t supported, so please don’t use them.
3. An incorrect partition scheme will stop disk auto‑resizing and machine naming from working.

 

Windows

1. Install “Red Hat VirtIO SCSI pass‑through controller”

   When you see the “Where do you want to install Windows?” prompt, click “Load drivers” and pick the matching driver. The storage drive will then appear.

2. Initial Setup

     Click I don’t have internet when asked “Let’s connect you to a network”

     Select Continue with limited setup on the “There’s more to discover…” screen

     Enter any username but leave the password blank

3. Install Virtio‑win drivers and guest agents

    Once the machine has started and you’re logged in, open CD Drive E and run Virtio‑win‑guest‑tools to install the VirtIO drivers along with spice vdagent and qemu guest agent. Click Next and OK to finish.

4. Disable Hibernate 

    Right‑click “Command Prompt” and choose “Run as administrator”, then enter powercfg.exe /hibernate off and press Enter.

5. Enable Shutdown/Restart Windows 10 without Any Prompts

     In the Registry Editor, go to the key HKEY_USERS\.DEFAULT\Control Panel\Desktop.

     Create a new String Value called AutoEndTasks and set its value to 1.

      

 

6. Check if the required services exist and set them to “Automatic Start”

7. Install and configure TightVNC for proper VNC connections

    Download the TightVNC installer for Windows from https://www.tightvnc.com/download.php.

    Run the installer and, once finished, disable authentication.

Install Tightvnc

    Open “TightVNC service configuration” and adjust the settings.

Configure tightvnc

 

8. Enable Shared‑drive

    Shared‑drive makes it possible to exchange files between cloud desktops during a training course, or between your own PC and the cloud desktop. It uses WebDAV technology. You’ll need to map the drive before you can use it – see the screenshot below for the steps.
