+## Windows sandbox
+
+SmolVM can boot a Windows 11 guest as well as Linux. Hand it a Windows image and you get the same Python and CLI you use for Linux — run PowerShell, upload files, set environment variables, and run many sandboxes in parallel from one baseline image.
+
+```python
+from smolvm import SmolVM
+
+with SmolVM(
+    os="windows",
+    image="~/.smolvm/images/win11.qcow2",
+    ssh_user="smolvm",
+    ssh_password="smolvm",
+) as vm:
+    print(vm.run("Write-Output 'hello from windows'").stdout)
+```
+
+Build your own image from a Windows ISO:
+
+```bash
+smolvm windows build-image --iso ./Win11.iso \
+    --virtio-win-iso ./virtio-win.iso \
+    --output ~/.smolvm/images/win11.qcow2
+```
+
+Windows guests need a Linux host with KVM. Host mounts, network controls, and snapshots are Linux-only today. See the full [Windows guide](https://docs.celesto.ai/smolvm/guides/windows-guests) for details.

 ## Coding agents
 
 It sucks to “press enter and accept changes” every few seconds while using coding agents. SmolVM makes it easy to isolate the agent coding environment from the host (laptops).
