Microsoft is pushing out updates to System Center Configuration Manager at an incredible pace and to assist with that 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 are on the other hand released only a few times per year and contain stable, tested features that are mature enough to release into production environments.
A new year has arrived and with it, another release. System Center Configuration Manager Technical Preview 1701 is now available, and it offers the following new feature
- UEFI inventory data – Hardware inventory can now determine whether the device is UEFI-enabled.
- Express files support for Windows 10 Cumulative Update – Configuration Manager can support Windows 10 Cumulative Update using Express files. This functionality is only supported in Windows 10 version 1607 with a Windows Update Agent update included with the updates released on January 10, 2017 (Patch Tuesday). For more information see https://docs.microsoft.com/sccm/core/get-started/capabilities-in-technical-preview-1612#express-installation-files-support-for-windows-10-updates.
- Validate Device Health Attestation Data via Management Point – You can now configure management points to validate health attestation reporting data for cloud or on-premises health attestation service.
- Updated Content Library Cleanup Tool – The command line tool (ContentLibraryCleanup.exe) used to remove content that is no longer associated with any package or application from a distribution point (orphaned content) has been updated with fixes for known issues.
- Host software updates on cloud-based distribution points – Beginning with this preview version, you can use a cloud-based distribution point to host a software update package.
- Support for Microsoft Azure Government cloud added to Operations Management Suite (OMS) Connector feature – You can now configure an OMS connector for the OMS workspace on Microsoft Azure Government cloud.
- Additional boundary groups improvements – Clients now find software update points using Boundary Group associations.
This also includes several improvements to operating system deployment, many of which were the result of your User Voice feedback:
- Support for more applications for the Install Applications task sequence step
- Expire standalone media
- Support for additional content in stand-alone media
- Configurable timeout for Auto Apply Driver task sequence step
- Package ID is now displayed in task sequence steps
- Windows 10 ADK tracked by build version
- Default boot image source path can no longer be changed
