XP Repair Pro is a popular registry cleaner and PC optimization software designed to work with Windows XP - although it is also compatible with Windows Vista.
It is perhaps one of the more popular registry cleaners, as it has had over 1.42 million downloads in just under 2 years. It has also received favorable reviews from software review giants such as Cnet's download.com and Softpedia.
The latest "2008" version is capable of detecting and repairing over 60,000 of the most common errors that you may experience with a windows computer.

Features:
XP Repair Pro is packed with the usual features you would expect from a registry cleaner, as well as several additional ones you may not expect.
The first feature available to registered users of XP Repair Pro is an additional program called "Stop Starting". This is a free easy-to-use application which allows you to stop certain programs from starting up automatically when your computer loads. This will considerably increase the load-up time of your PC, as well as improve general performance.
Now if you're PC savvy, you'll know that it's possible to do this manually - but it can be a complicated process, which means this additional application is great for those of you who aren't as PC savvy.

XP Repair Pro also features and Advanced Registry Editor, which allows you to comfortably edit your registry settings manually. This is very handy if you're familiar with your windows registry, but isn't likely to be needed by the majority of users.
One of our favorite features about XP Repair Pro is the "software crash monitor". This feature will automatically monitor your computer processes, and if it detects something that is likely to cause an "illegal error" and cause your PC to freeze, lock-up, or crash, it will stop it from happening. This feature allows your computer to be much more stable.
XP Repair Pro features a Live Update facility, similar to that of Microsoft's. This means you will automatically receive free updates. In 2008, XP Repair Pro are planning a large update which will include a file shredder (to safely delete files without chance of recovery), privacy cleaning tools, and more.
In total, 8 new features are planned. When this is released, XP Repair Pro will become the most feature-packed registry cleaner and PC optimization software on the market.
