Recommended Posts


Microsoft have released the latest Technical Preview release of System Center Configuration Manager namely System Center Configuration Manager Technical Preview 1801.

There are two main versions (of Configuration Manager) available:

  •     System Center Configuration Manager (Current Branch)

  •     System Center Configuration Manager (Technical Preview)

System Center Configuration Manager (Current Branch) is designed for use in production, for managing anything from small to very large Enterprises whereas System Center Configuration Manager (Technical Preview) is for lab environments only and is limited to 10 clients. The Technical Preview releases are released monthly, and contain the latest and greatest features being trialed in the product, and usually these new features are the result of feedback from uservoice.

Current Branch releases on the other hand are released only a few times per year and contain stable, tested features that are mature enough to release into production environments.

System Center Configuration Manager Technical Preview 1801 is now available. This release offers the following new features:

  • Run Scripts – You can now import and run signed scripts and monitor the script results.

  • Moving Distribution Points between sites – You can now move an eligible distribution point from one primary site to another primary site or from under a secondary site to a primary site . For information about requirements for moving a distribution point see “Reassign Distribution Point”.

  • Improvements to client settings for Software Center – Client settings for Software Center now has a customize button where you can preview your customizations before deploying them to machines. You can also hide unapproved applications in Software Center.

  • New settings for Windows Defender Application Guard – For Windows 10 version 1709 and later devices, there are two new host interaction settings for Windows Defender Application Guard. Websites can be given access to the host’s virtual graphics processor and files downloaded inside the container can be persisted on the host.

  • Co-management reporting – You can now view a dashboard with information about co-management in your environment.

  • Phased Deployments – You can use phased deployments to automate a coordinated, sequenced rollout of software without creating multiple deployments.

  • Support for hardware inventory strings greater than 255 characters in length – For newly added classes, you can specify string lengths greater than 255 characters for hardware inventory properties that are not keys.

This release also includes the following improvements based on your feedback from UserVoice:

  • Improvements to Automatic Deployment Rule evaluation schedule – You can now schedule Automatic Deployment Rule evaluation to be offset from a base day.

Update 1801 for Technical Preview Branch is available in the Configuration Manager Technical Preview console. For new installations please use the recently updated 1711 baseline version of Configuration Manager Technical Preview Branch available on TechNet Evaluation Center.

We would love to hear your thoughts about the latest Technical Preview! We’re now enabling Configuration Manager feedback through the Feedback Hub app built-in to Windows 10.
