+# Testing the Firezone Windows client on a Windows server VM
+
+## Prepare VM
+
+1. Download and install Oracle VirtualBox <https://www.virtualbox.org/wiki/Downloads>
+1. Prepare a VM with 50 GB of hard drive, 2+ GB of RAM, and 2+ CPU cores (More resources will help Windows set up faster. We can reduce resources before testing Firezone)
+
+## Download VM image
+
+Download the 64-bit ISO from <https://www.microsoft.com/en-us/evalcenter/download-windows-server-2022>
+
+(Server 2019 requires a sign-up: <https://info.microsoft.com/ww-landing-windows-server-2019.html>)
+
+You should get this file: `SERVER_EVAL_x64FRE_en-us.iso`
+
+The Windows license is valid for 180 days
+
+## Install Windows Server
+
+1. In VirtualBox, mount the ISO as a CD/DVD
+1. Boot the VM and use F12, then 'c' to boot from CD/DVD
+1. When Windows asks what version to install, choose "Windows Server 2022 Standard Evaluation (Desktop Experience)
+1. Choose "Custom" to delete the old Windows install, if any, and re-install
+1. If there's any partition from a previous install, delete and recreate it
+1. Tell Windows to install on the primary partition
+
+## Windows first-time config
+
+1. Allow the PC to be "discoverable by other PCs and devices on this network", this might be needed for Firezone to work
+1. In the Server Manager, click "Manage", click "Server Manager Properties", check "Do not start Server Manager automatically at logon", and click "OK". Close Server Manager.
+1. Make any quality-of-life changes you want such as fixing the taskbar
+1. Open `https://ifconfig.net/` in Edge and clear out the Edge first-time setup
+1. In the VirtualBox menu, click "Devices", click "Insert Guest Additions CD image", and then install the VirtualBox guest additions, so you can drag-and-drop files into the VM easily.
+1. Perform a clean shutdown from within the Windows VM.
+1. In VirtualBox, take a snapshot of the VM so you can roll back to this state after installing Firezone.
+
+## Testing Firezone
+
+1. Copy-paste an MSI built from CI/CD into the VM and install Firezone
+1. Test Firezone as usual
