The Registry

The Registry is a database used to store settings and options for Microsoft Windows 95, 98, ME, NT, 2000, and XP. It contains information and settings for all the hardware, software, users, and preferences of the PC. Whenever a user makes changes to a Control Panel setting, File Associations, System Policies, or installed software, the changes are reflected and stored in the Registry.

The Registry has a hierarchal structure. Although it looks complicated, the structure is similar to that of Windows Explorer. The Registry can be edited. It is strongly recommended that you leave this to the experts. You can muck up your computer if you unwisely modify the Registry.

Backing Up The Registry
It is a very, very good idea to backup the Registry manually at least once a month. It only takes a few moments and could prevent headaches later. The Registry Editor is able to import and export registry settings to a text file, identified by the .reg extension. You will use this export feature to backup the Registry.

1. Click the Start button, and then click Run
2. In the Run box, type “regedit” (without the quotes), and then click OK
3. When the Registry Editor opens, click on the Registry menu item.
4. Click Export Registry File.
5. In the File Name, box type in what you want to call this backup. A suggestion would be to include the date in the name. For example, you could call the backup you do today, "Registry Backup 2004-12-11."
6. Click the Save In box and select the Desktop. (You should transfer the file to a disk later. It’s rather large, so use a CD, Zip disk, or other large capacity, removable media.)
7. For Export Range, be sure All is selected, and then click OK.
