+  Install / update / remove the TrafficAudit backend as a Windows service.
+
+  The service is a WinSW (Windows Service Wrapper) host: trafficAudit.exe reads
+  trafficAudit.xml and runs "java -jar traffic-audit-server.jar".
+  Because it is a real Windows service it starts at boot with no user logged on,
+  is listed in services.msc / Get-Service, and is restarted by the Service
+  Control Manager when the java process dies.
+
+  Run from an ELEVATED PowerShell in the backend folder
+  (the folder that contains the jar, application.yml, docs, web and trafficAudit.exe):
+
+    powershell -NoProfile -ExecutionPolicy Bypass -File install-service.ps1

+    powershell -NoProfile -ExecutionPolicy Bypass -File install-service.ps1 -JavaPath 'D:\jdk8\bin\java.exe'
+
+  What it does:
+    1. locates java.exe (JAVA_HOME -> PATH -> JavaSoft registry -> Program Files)
+    2. writes that absolute path into trafficAudit.xml (<executable>)
+    3. installs or reinstalls the service and starts it (unless -NoStart)
+
+  Notes:
+    - Re-running is idempotent: an existing service is stopped and reinstalled.
+    - Logs: logs\trafficAudit.out.log / logs\trafficAudit.err.log (10 MB x 10 roll).
+    - Do NOT enable the scheduled-task autostart (install-autostart.ps1) at the
+      same time: two hosts would race for the same jar and port 8090.
+    - Keep this file ASCII-only; Windows PowerShell 5.1 reads a BOM-less .ps1 as ANSI.
