The Windows registry is the central database of Windows. It contains information and settings for hardware, every program installed on the system, and user settings. Whenever a user makes changes to Control Panel settings, or installed software, the changes are reflected and stored in the Registry.

     
 

Your registry keeps growing while you are using the computer. Over time, a large number of obsolete, redundant, and invalid entries and registry holes accumulate within the registry, causing it to grow at an unwarranted rate, and eventually damaging, corrupting, and fragmenting the registry. A good registry cleaner will clean up and fix your registry errors and make your PC run faster and more smoothly.

“Excellent program. I've tried several optimizers and Perfect Booster is my favorite! It did improve my PC performance and never caused any trouble to me (my PC crashed before using some other registry cleaners). I'm so glad that i finally found one that can be trusted!”

“Perfect Booster is the Best of the bests!!! Very friendly UI, and works just as it's supposed to. I deleted more than 600 registry items, and my machine is running smoother than it has in quite a while. I've used this utility dozens of times with no problems. Highly recommended”
