With Customizer XP's Create Shortcut function, you can create a special shortcut for your favorite programs, allowing you to set both the application's processor priority and free RAM, before the application is launched. Using a higher processor priority will increase your favorite program's performance.
Customizer XP's Process Info displays a list of all running programs, and allows you to change the processor priority setting for all programs. Using the Startup Manager, you can take control of all items that will run at Windows startup. The program's Add/Remove function lets you easily edit Windows add/remove items, getting rid of entries for leftover, uninstalled programs.
