Defragmenting the Registry

In the following chapters, you will find out how you can use the TuneUp Registry Defrag module to reduce

the size of the registry by defragmenting it and why it is important to do so.

Introduction

The registry is the heart of a Windows system. It is where Windows continuously stores entries (values and

keys). In addition, each newly installed program and every newly connected hardware is entered in the reg-

istry where it records keys and values.

This causes the registry to get bigger and bigger. However, the bigger the registry, the longer the system

needs to find certain information requested at any given moment by a program - Windows then becomes

slower. When a program is uninstalled or when the registry is cleaned up, these keys and values are usually

deleted, but despite this the registry does not get any smaller. Why is this? The space previously taken up by

a deleted key continues to exist in the registry - even if it is no longer used. At some point your registry then

looks like a piece of Swiss cheese - full of holes.

This is a real waste of space at the expense of system performance - not just on the hard disk but also in the

memory. TuneUp Registry Defrag is able to compress the registry so that it becomes much smaller. This

function increases the stability of your Windows system.

TuneUp Registry Defrag analyzes the registry and creates a completely new version of it containing only

the intact data, in the correct order. The old registry is deleted following this step and automatically

replaced with the new version when the computer is restarted.
