Question : How to lower commit charge in windows XP

My commit charge seems to always grow, as if the memory does not get release after I close programs.  I also tried to run Tune Up Utilitie's memory optimizer but it didn't help. Is there an other way to lower the commit charge?

The commit limit may be increased by either creating additional pagefiles or, if pagefile expansion is enabled, by expanding an existing one. The operating system will expand the pagefile automatically, if possible, when the total commit charge approaches the limit. In such an event a popup window will be displayed stating that "The system is running low on virtual memory."
