      Description

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

        <numExecutors>12</numExecutors>
        <mode>EXCLUSIVE</mode>
        <retentionStrategy class="hudson.slaves.RetentionStrategy$Always"/>
        <launcher class="hudson.os.windows.ManagedWindowsServiceLauncher" plugin="windows-slaves@1.2">

          <password>{xxx}</password>

        </launcher>
        <label>kernel windows x86_64 release</label>
        <nodeProperties/>
      </slave>
      

      Any advice is greatly appreciated. - Thanks.
