+# Microsoft Server 2025
+
+This directory contains the following node definition:
+
+- `win2025.yaml` - Microsoft Windows Server 2025 node definition
+
+### Image Availability
+
+VHD images can be downloaded from microsoft on a trial basis here:
+
+- [Evaluation Center](https://www.microsoft.com/en-us/evalcenter)
+
+Then the VHD image will have to be converted to a .qcow2 format. Linux qumu-img makes it easy.
+
+For example:
+
+```sh
+qemu-img convert -f vpc -O qcow2 \
+  26100.1742.amd64fre.ge_release_svc_refresh.240906-0331_server_serverdatacentereval_en-us.vhdx \
+  26100.1742.amd64fre.ge_release_svc_refresh.240906-0331_server_serverdatacentereval_en-us.qcow2
+```
+
+### Notes
+
+This node definition uses 16g of RAM and 4vcpu's. Anything less than that and it tends to become buggy.
