Installing a windows slave is currently looking like knight fight!

JNLP looks like the simplest solution, but we can't rely on this solution to setup automatically slaves with scripts and turn Jenkins as a service. There are many pittfalls with rights, registry tricks and .net FW or java security...

The jenkins-slave.exe is not reliable at all neither... to do the job.

We definitively need a much better slave installation method that allows scalable and scriptable slave installation without asshole. There are plenty of sofware who does this for years, so I don't understand why Jenkins can't!

Jenkins is not only used in Linux world!!!
