Overview

Every account can install Windows Server automatically. You can reinstall any of your servers to Windows Server from the Reinstall tab of the Ascienth console, the same way as any other operating system. See our Server Reinstallation guide. The Reinstall tab offers these versions:
  • Windows Server 2019
  • Windows Server 2022
  • Windows Server 2025

​
Licensing

Automatic installations use the Evaluation Edition of Windows Server, which shuts down after 180 days without a license. If you need the server to keep running beyond the evaluation period, you will need to supply and apply your own Windows Server license. See Server Stopping Every Hour for what happens when the evaluation period ends.

​
Manual Installation

If you need a Windows version or edition that the Reinstall tab does not offer, you can install it manually through the Custom ISO feature of the Ascienth console. See our Manual Windows Installation guide for full instructions, including the VirtIO drivers required to see your disk during setup.
Manual Windows installations are unsupported. We cannot troubleshoot them or install Windows for you, and you will need to be accustomed to installing Windows Server manually through the ISO image. You are also responsible for your own Windows licensing.
