#A quick note on the API call itself. This is the same API used by Microsoft in its empty.exe in the Windows 2003 Resource kit. This is also the same api that all .Net programs use by default when you minimize them and their memory lowers. So now instead of being just for .Net, Cleanmem lets you use it on all your programs.
