Versions:
RAMKeeper is a lightweight RAM cleaning utility for Windows, published by Ashish Patel and currently available in version 1.1.0, the only released version of the software to date. The application is distributed as a remarkably compact 163 KB static binary with no runtime dependencies and no installer required, making it suitable for portable use. Its core purpose is to reclaim system memory by purging the standby and cached memory list through the native Windows NtSetSystemInformation API, allowing memory to be recovered immediately without requiring a system reboot. RAMKeeper runs silently in the system tray, staying out of the way during normal use while remaining accessible. The software includes a status window that displays a RAM sparkline visualization alongside a history of previous cleaning operations, and a per-clean log provides a record of each memory purge. Cleaning can be triggered manually through the global hotkey Ctrl+Alt+R, or automatically through configurable auto-clean modes based on a memory threshold, a fixed interval, system idle state, or a schedule. To prevent unwanted interference with specific applications, process exclusions can be defined so that selected programs are left unaffected by cleaning operations. Additional convenience features include balloon notifications to report cleaning results and an option to start automatically with Windows. As a system utility, RAMKeeper falls into the memory optimization and system maintenance category and is relevant for users who want to free cached memory on demand, reduce memory pressure on machines with limited RAM, or automate routine memory cleanup without installing a heavier suite of tools. Its combination of a tiny footprint, silent tray operation, flexible trigger options, and detailed logging makes it a focused single-purpose tool rather than a general-purpose optimizer, addressing one specific task—standby memory reclamation—in a minimal and self-contained package.
