 UltraVNC is disabled by default. The `-Vnc` option starts it at launch; DeployCenter then disables the WinPE firewall to allow VNC connections. Use this option only on a controlled deployment network: it disables the WinPE firewall as a whole.
 
+To use `-Vnc`, extract `tools/uvnc.zip` into the parent folder of `DeployCenter`, so the `uvnc` folder sits alongside `DeployCenter`:
+
+```text
+<parent folder>/
+├── DeployCenter/
+└── uvnc/
+```
