Summary
This article explains how Windows reserves a portion of system RAM for hardware and system processes, often without users realizing it. It details what Windows RAM reservation is, why it happens (system stability, hardware mapping, SuperFetch/Prefetch), and provides step-by-step methods to reduce or reclaim reserved RAM, including adjusting virtual memory, disabling SuperFetch, modifying Registry settings, and using third-party tools. The article aims to help users free up memory for better performance, especially on systems with limited RAM.
