CleanMyPC Registry Cleaner. This software is very easy to install and immediately on the first time of its launch on the local computer, allows the user to take an instant backup of the current registry. This is very important because, if for some reason you have manually deleted a good part of registry you can reboot the computer in the safe mode and can restore the registry information.

To backup the registry simply click on the “Backup Windows Registry” button and the computer will take around 2 minutes to store the backup file in user’s specified location on the local hard drive. The next thing that you can do is to select the “Scan & Clean” option from the let Navigational panel. This will allow the application to scan through the registry for File Extensions, Application paths, Registry Integrity, Com/ActiveX entries, Uninstall Entries, Font Entries, Shared DLLs, Help Files Information, Windows Startup Items, History List and finally a File/Path Reference (only for advanced user).

You can be amazed by the fact that, if there are more than 400 errors reported by the registry cleaner on your windows XP machine they can be fixed in a single click on the “Fix selected problems” button. Only 10 problems are repaired as you are running a trial version of the software before. You don't have to waste any time but immediately purchase the original version and rescan your system registry and get every error fixed after which your computer reboots. Once you come back online it is faster and applications are opening instantly which gives you a 30 – 40 seconds delay previously. Your computer boot-up time is reduced to 1-2 minute from 5-7 minutes. This is simply awesome.

You can now use the “Defrag Registry” option which will reduce the registry size to a lot smaller to your surprise. Apart from that the “Startup organizer” allows a user to look at the startup items running on your computer which can play a significant role in downgrading your computer’s performance. Uncheck those items which you don’t want to initialize and start with a computer startup.

Finally an awesome “Privacy Eraser” option allows the user to kill every major browser’s (like IE, Firefox, AOL, MSN, Opera) cache, cookies, off line files, URL history, saved user name and password and index.dat file used by Internet Explorer, to save up on disk space. You can also clear a lot of windows and Office based cache and temporary files as well.
