Unlike other tuneup utilities, CachemanXP runs as a system service, minimizing resource usage and tweaking Windows at system-level. Outertech's Windows tuneup utility has been designed to improve the performance of a computer by optimizing several caches and fine tuning a number of system settings. Oneclick-Optimization makes it suitable for novice and intermediate users yet powerful and versatile enough for experts. Backups of settings ensure that all user modifications can be reversed with a single click. CachemanXP uses minimal resources and virtually no CPU time.
