MemoryCleaner is a straightforward tool to help your machine's memory with a single click.
MemoryCleaner comes displayed from a no-frills but functional UI that is virtually foolproof even for the most novice of users. It shows live counters for physical and virtual memory and a single function button for cleaning. A couple of configurations are available to allow for auto cleaning, like clean when above a user-defined percentage or by time intervals. It can additionally be set to load on system startup if desired.
It doesn't get much more simple than this tiny tool for automatic and user-requested memory maintenance.
