      After upgrading the master to Jenkins v2.50, the Windows slave (working before) does not start any more, but only reports the following error:

          I also created JENKINS-42743 in order to update the Windows Slaves plugin.
          I will try to deliver a fix today just to have a temporary solution.

          JENKINS-42746 - Make the plugin independent from the XML sample in the core

          In Jenkins 2.50 we have got JENKINS-42724, which has been caused by the usage of the old resource file located within the Jenkins core.
          It is likely a leftover from the migration of the windows-slaves-installer module.

          Since the Windows Slaves plugin has its internal macro resolution logic, the sample should be also inside plugin. A longer-term fix is to make the plugin depent on the Windows Agent Installer module

          Windows Slaves plugin performs a direct access to the resources bundled into the core.
          Hence the file removal was a bad idea though I have not seen the issue in automatic tests and ATH.

          This change also was a last-minute change in https://github.com/jenkinsci/jenkins/pull/2765/ in order to address suggestions from @daniel-beck, hence I didn't test it properly

          The fix has been released in 2.51. I and danielbeck have a follow-up to think about the detached version requirements to enforce update of Windows slaves to the latest version where possible
