WINDOWS REGISTRY

What is the Windows Registry?

Think of the Windows registry as a control center for your computer. Windows settings, individual program settings, and other important configuration information are stored here.

Accessing the Windows Registry Editor

In Windows 7, press the start button, type regedit, and press Enter.
In Windows Vista, press the start button, type regedit, and press Enter.
In Windows XP, press Start > Run (WINKEY + R) and type regedit and press Enter.
When the registry loads you will be presented with a screen that looks like Figure 1. The registry is made up of the following components:

• Keys
• Subkeys
• Values
