As one tries new software, and new applications are not always up to scratch, the system registry gets more and more "dirty" - that is, there appear keys with no parameters or wrong keys that slow down system startup and performance. To manually delete those keys would be way too insecure. Use RegScrubXP for this purpose.
     RegScrubXP is a registry cleaner for Windows 2000/XP. It clears all the unnecessary keys, leaving you with a perfect registry that leads to better and more stable system performance. You can let the program scan for problem keys and then select the ones you feel safe to delete, or pick your own way through the registry and fix the wrong keys yourself. There are also additional tweaks for Windows XP users, including changing current user name and more.
     The tool is invaluable for those who need to get rid of junk keys on their NT-based system. Download it today and see for yourself.
