Starting with Windows 10 version 1809, including , you no longer need to download a standalone installer from a website. Instead, the tool is included as a "Feature on Demand" within the operating system. Prerequisites for Installation

In the era of Windows 7 and earlier, administrative tools were often included by default or installed via a bulky, standalone downloader. With Windows 10, Microsoft transitioned these tools into Features on Demand (FoD). Windows 10 20H2, released in the latter half of 2020, stabilized this approach. Unlike previous versions where an administrator might search for a specific "ADUC download" on the Microsoft Download Center, the process became integrated directly into the operating system settings.

A critical aspect of discussing the "download" of ADUC for Windows 10 20H2 is addressing the confusion that arose around this time regarding the term "RSAT." Historically, users searched for "RSAT download." However, with the release of Windows 10 20H2 and subsequent versions, Microsoft officially deprecated the acronym "RSAT" in favor of "Windows Server Remote Management." Despite this rebranding, the community and the user interface within 20H2 still largely referred to the tools by their legacy names.
