Memory Booster frees up memory in RAM by sending messages to Windows to clean up the workspace and for processes it no longer needs (Clear Processes Working Set). It is not a placebo memory optimization engine and will not force any memory out of RAM.
Memory Booster will make a Windows API call that tells Windows to clean up the workspace of all processes thus freeing up any memory, processes no longer needs. It will do this periodically to help improve the speed and the stability of your system.
This method will not free up a big amount of RAM, but instead will improve the stability and performance of your computer. This will also cure memory leaks and in some cases has been able to unfreeze programs. Because it uses a Windows API call, it’s safe to run.
