Following are some of the major features offered by System Center CONFIGURATION Manager (SCCM):  

• Operation System Deployment: SCCM provides an organization with all the tools it needs to deploy an operating system to client computers in a network - either via an image installation or via a scripted installation.
• Patching & Updating of OS: After installing the operating system successfully, SCCM starts patching and updating the systems. WSUS is used in most organizations to patch and update servers. SCCM, however, leverages WSUS' advantages and provides IT, administrators, with active patching in addition to WSUS.
• Asset TRACKING: Following the installation of a required operating system and any subsequent updates or patches, such systems must be kept up to date with further timely updates or patches. With SCCM, you can keep track of the hardware and SOFTWARE assets of the system.
• Remote Control: Whenever a user or system encounters an issue requiring further assistance from an IT administrator, they can remotely access the system to assess the issue. Using SCCM's remote-control feature, IT administrators and support engineers can access the system remotely.
• Reporting: SCCM COMES with a report generation tool that can generate reports based on the criteria outlined by the IT administrators. There are different types of reports based on what is required, such as reports of missing patches or updates, reports of standard configurations, inventory reports, etc.
• Internet Client: SCCM is a truly powerful tool that enables remote access to devices like mobile devices or remote systems without necessarily bringing them into the VPN network. Now, this can be done via an Internet client and an installed PKI (Public Key Infrastructure) certificate. These prerequisites will enable SCCM to AUTOMATICALLY connect to that system anywhere in the world to inventory, patch, update, and monitor it.
• Desired Configuration Management (DCM): It is the feature that complies with the IT guidelines laid down by an organization, and the standard configuration of a system cannot be modified/altered. With DCM, you can ensure that your managed systems are compliant with key configuration settings that are important to your organization. It ensures that all systems have the same software setup, drivers, updates, and configuration settings.
