Why is this so? The reason is nearly always a corrupt registry which has become bloated with data and useless files. Every time you install or uninstall a program incompletely, fragments of the program will remain in the registry causing it to become choked with data after some time.

The registry is something which all Windows PCs have. It is basically a database of entries which the operating system uses to run the machine. When it becomes bloated with too many fragments of data the operating system has to find its way through all the excess entries to locate the data it needs to run the computer and programs. This causes a very noticeable slow down and balkiness in the operation of the machine.

The only way to correct this problem is to remove all the unwanted data entries from the registry. All windows PCs have a function called Regedit which is intended for just this purpose. You can access Regedit by clicking START-RUN then typing Regedit in the box. When you are ready to start using Regedit you must first back up your registry so that you can restore it if something goes wrong. This is done by clicking FILE then selecting EXPORT. Name the backup file so that you can find it and save to your desktop or elsewhere.

You can now proceed to go through the registry entries and remove any you do not want. When you examine the registry entries you will see that you are faced with a formidable task. Unless you really know what you are doing it will be obvious to you that you need help at this point. Just remove one wrong entry and you can completely disable the computer which we certainly do not want to do.

Fortunately help is readily available in the form of an online registry cleaner application which can do the job quickly and safely. A good registry repair utility will backup your registry then delete all unecessary entries from the registry. This will easily and safely clean the registry in a matter of minutes and return the computer to being the sweet running fast machine it was before the registry became corrupt.

We purchased several of the most popular registry cleaner applications and tested them to see which was best. We found that they vary greatly in ability to detect errors in the registry. The best registry cleaner applications could detect many more wrong entries than some of the others.
