Automated Windows Server Installer for Hetzner
Unattended Windows Server 2016 / 2019 / 2022 / 2025 — installed from the Hetzner rescue system in about 40 minutes.
How it works
- 01
Boot the server into Rescue Mode
In your Hetzner Robot panel, enable the Linux Rescue System for the server and reboot it. Connect via SSH once rescue is up.
- 02
Fill the form and generate
Enter your server IP. Gateway and password are optional — they're auto-detected or use a secure default. Pick your Windows version and click Generate.
- 03
Paste the command in your rescue shell
Copy the generated curl … | bash command and paste it into your SSH session. The installer handles everything automatically.
- 04
Wait ~40–60 minutes, then RDP in
The script downloads the ISO, installs Windows, configures networking & RDP, then reboots. Connect via RDP on port 3389 when done.

Frequently asked questions
How long does a Windows Server install take on Hetzner?
Typically 40–60 minutes end to end. The script downloads the official ISO from Hetzner's mirror, builds a custom unattended image, installs Windows, then configures networking and RDP before a final reboot.
Which Windows Server versions are supported?
Windows Server 2016, 2019, 2022 and 2025 (Standard, Desktop Experience). 2022 is recommended for most servers.
Does it work on Hetzner auction (server-bidding) and dedicated servers?
Yes. It runs from the standard Hetzner Linux Rescue System and supports both UEFI and Legacy BIOS hardware, including AMD Ryzen and Intel Xeon auction boards with Realtek NICs.
Do I need to install anything locally?
No. Everything runs in your server's rescue shell from a single curl … | bash command. You only need an SSH client and, optionally, a browser to watch the live VNC console.
How do I reset a forgotten Administrator password?
Use the Password Reset tab. Boot into the Linux Rescue System and run the generated command — it sets the new password offline and applies it on the next boot, with no existing password required.
Is RDP reachable right after installation?
Yes. The installer enables Remote Desktop, opens TCP 3389 in the firewall, configures static networking and stages NIC drivers, so you can connect on port 3389 once the server finishes booting.
