How to make jenkins agent service on windows

• First download the jnlp file from browser
• Right click go around and set the file type to open using javaws command. This steps may not needed
• Start cmd terminal as Admin and go to the download folder
• Run javaws -verbose (have to set -verbose otherwise it just exits)
• When it runs and connected, click File / Install as Service
• Quit that program
• Check in the service it should start. But for some reason we need the option -noCertificateCheck in then
• In the service findout where the java wrapper is. Get into that folder (d:\jenkins) look at the config jenkins-slave.xml - edit and put that option in.

echo "start jenkins agent"
cd /home/jenkins
java -jar agent.jar -jnlpUrl https://jenkins.xvt.technology:4343/computer/<NODE_NAME>/slave-agent.jnlp -secret XXXXXXXXXXXX -workDir "/var/jenkins" -noCertificateCheck &

Someday I can make it as fully systemd service unit file with whistle and bells but for now
