Hi,
Microsoft Windows Deployment Services (WDS) and Microsoft Deployment Toolkit (MDT) are both tools that help automate the deployment of Windows operating systems. WDS is a server-based technology that enables network-based installation of Windows operating systems, while MDT is a free, lightweight tool that helps customize and deploy Windows operating systems on desktops, laptops, and servers .
On the other hand, System Center Configuration Manager (SCCM) is a comprehensive management solution that provides a unified infrastructure for managing and deploying software, hardware, and operating systems. SCCM OSD (Operating System Deployment) is a feature of SCCM that enables administrators to deploy Windows operating systems to computers in an organization.
In summary, while WDS and MDT are more suitable for small-scale environments, SCCM OSD is a more comprehensive solution that is better suited for large-scale environments. MDT is free and great for tiny environments without a lot of computers to migrate, while SCCM is a much more complex tool that allows you to do a lot more than MDT does.
MDT operates with admin privileges, while ConfigMgr uses SYSTEM.
