Windows XP is the most popular operating system till now. Millions of people use windows XP Professional and Windows XP Home though despite of release of windows vista and windows 7. I also have Windows XP Professional on my one PC and I don't want to upgrade or replace it. It's the most stable version of windows which consumes much less memory than the vista and 7.0.
Though windows XP is one of the fastest operating system, but sometimes one can see his/her computer becomes slower and slower. There are various reasons of your computer becomes slower or responds slowly. One of the reasons is due to registry. Windows Registry sometimes become a junkyard or corrupted. You have to clean the registry regularly. If the registry is clean then your computer will become a bit faster.
So if you want to clean your registry I can suggest a nifty software which I found most useful. There are many other softwares for cleaning and repair registry of windows XP. But the Registry Easy is easy to install and very easy to use it. It offers plenty of options to customize your needs. Just check this out and feel the difference.
