Unlike other tuneup utilities, CachemanXP runs as a system service, minimizing resource usage and tweaking Windows at system-level.

CachemanXP will backup your system settings (so you can always revert any changes!). The Auto-Optimize feature will examine your system and tweak it for best performance. With one click of a button! From version 1.60 on Auto-Optimize tweaks also the DNS Cache for improved Network and Internet performance.

Here is an example of a system tweak:
• Most Windows users know and dread this Automatic Updates dialog.
• In the middle of your work or entertainment session Windows can display this dialog. Since you want to go on with your work, you click on Restart later.
• But Windows will not leave you alone. The dialog will reappear every 5 minutes, no matter what. It gets even worse, it will stay on top of all other programs, in some cases even in front of a movie you are watching.
• If you use CachemanXP to tweak your system, you can prevent this dialog from showing up and restart your system when you are done with your work.
• The tweak lets you only decide when to restart your system, the updates will still be installed!
• With two clicks in CachemanXP you can get rid of this dialog for ever.
• Go to the Tweaks tab.
• And turn on the Don't show Automatic Updates restart dialog checkbox.
