This doesn't work like other memory cleaners that do nothing but force windows to free up memory by using up all the avail. memory. This old trick then causes your system to lag big time!
Cleanmem works in a matter of about 5 sec. It uses a windows api call that is in Windows2000,xp,2003,Vista &; 2008 that tells windows to cleanup the workspace of a processes thus freeing up any memory the process no longer needs. Other memory cleaners end up forcing the memory into the page file slowing down your system. This tool does not. The API call frees up unused memory from programs, when a program needs the memory again it can simply take it back instead of forcing the memory out of ram and into the page file.
A good example is this, say you have quickbooks installed and setup for multi user mode. The quickbooks service takes 37mb of memory just sitting there! when cleanmem is ran it uses only 600kb and wont grow again until it actually is used. The same goes for all processes.
