The Windows operating system makes it very easy for people to set individual user preferences within Windows and within different software and hardware programs.  The mechanism that allows this to happen is the Windows registry.  The registry is a complicated series of files and folders that store all the information regarding preferences and settings.  The thing is, the registry tends to get cluttered and corrupted over time as you use your computer dynamically.  The only solution is to get the best Windows XP registry cleaners you can find and run them on a bi-weekly basis.  Often these programs can help you immediately and speed up your computer, especially if it’s being bogged down by a cluttered registry.
