Giới Thiệu · Tweaking Utility
This utility is for any serious Windows tweaker. Change hundreds of Registry settings in Windows XP, improving appearance, performance, and functionality. Prevent others from changing your settings, locking down Control Panel applets and Internet Explorer options, even choosing which applications can or can't run on the computer. You can change Windows XP's performance by selecting to keep the core system in memory and not paged to disk (advisable only if you have 512MB RAM or greater).
You also can optimize the CPU and memory usage for programs, the system cache, or background services. Version 2.2 fixes the bug with time expiration.
