    Project: cMDTBuildLab (
      * Remove dependency for PsIni module
      * Remove cleaning of MDT Captures folder: each new captured WIM is builded with timestamp date at file name for history tracking,
        you can delete or move old images from external scripts
      * Run Reference VMs as Job at Hyper-V host: it's faster
      * Remove "ConcurrentRunningVMs" param from config: cMDTBuildLab build maximum to 8 concurrent VMs.
        Tune need count with count of reference Task Sequences in the REF folder
      * Remove cleaning of CustomSettings.ini after build: this is a job for DSC configuration.
        Configure DSCLocalConfigurationManager on MDT server with
            ConfigurationMode = "ApplyAndAutoCorrect"
            ConfigurationModeFrequencyMins = 60
      * Possibility of sending build results to E-mail
