The utility for any serious Windows tweaker allows users to change hundreds of registry settings from Windows XP, improving appearance, performance and functionality. Prevent others from changing your settings, increase Windows security. Lock down Control Panel applets, Internet Explorer options, even choose which applications can or can't be run on the computer.
You can change Windows XP's performance by selecting to keep the Windows XP core system in memory and not paged to disk (advisable only if you have 512MB RAM or more). You can also optimize the CPU and memory usage for Programs, System cache, or background services.
You can also use the TweakXP.com Tweaking Utility to add "unremovable" Windows components (such as Microsoft Messenger) to "Add or Remove Programs" and uninstall these components after all.
