I want to install windows agents as a service, following that manual
https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+as+a+Windows+service#InstallingJenkinsasaWindowsservice-InstallSlaveasaWindowsservice(require.NET2.0framework)
But there is no "File" > "Install as Windows Service" menu!
Me is dumb. should have been using the last version from the beginning
