CachemanXP is a system service designed to improve the performance of your
computer by optimizing several caches, auto-recovering RAM and fine tuning
a number of system settings. Auto-Optimization makes it suitable for novice
and intermediate users yet it is also powerful and versatile enough for
computer experts. Backups of settings ensure that all user modifications
can be reversed with a single click.
Due to the system service nature it requires Windows NT4/2000/2003 or XP
to run, uses minimal resources and virtually no CPU time. The help file
includes a screenshot based system performance guide.
