PrioSet
is a simple program launcher that lets you set the system level
priority of any application. PrioSet can relieve your processor
by lowering the share of resources that goes into background
processes. Just set their priority to 'Idle' and they won't
bother you anymore. You can also make sure the CD burner program
gets enough processor power by selecting 'Real time' mode. Command
line arguments are also supported. (PrioSet has only been tested
on Windows XP. No system files will be overwritten during installation.)
