he Structure of the Registry
The Registry has a hierarchal structure, although it looks complicated the structure is similar to the directory structure on your hard disk, with Regedit being similar to Windows Explorer.
Each main branch (denoted by a folder icon in the Registry Editor, see left) is called a Hive, and Hives contains Keys. Each key can contain other keys (sometimes referred to as sub-keys), as well as Values. The values contain the actual information stored in the Registry. There are three types of values; String, Binary, and DWORD - the use of these depends upon the context.
There are six main branches, each containing a specific portion of the information stored in the Registry. They are as follows:

There are three types of values; String, Binary, and DWORD - the use of these depends upon the context.
There are six main branches, each containing a specific portion of the information stored in the Registry. They are as follows:
• HKEY_CURRENT_USER - This branch links to the section of HKEY_USERS appropriate for the user currently logged onto the PC and contains information such as logon names, desktop settings, and Start menu settings.
• HKEY_LOCAL_MACHINE - This branch contains computer specific information about the type of hardware, software, and other preferences on a given PC, this information is used for all users who log onto this computer.
• HKEY_USERS - This branch contains individual preferences for each user of the computer, each user is represented by a SID sub-key located under the main branch.
• HKEY_CURRENT_CONFIG - This branch links to the section of HKEY_LOCAL_MACHINE appropriate for the current hardware configuration.
• HKEY_DYN_DATA - This branch points to the part of HKEY_LOCAL_MACHINE, for use with the Plug-&-Play features of Windows, this section is dynamic and will change as devices are added and removed from the system.
Each registry value is stored as one of five main
• REG_BINARY - This type stores the value as raw binary data. Most hardware component information is stored as binary data, and can be displayed in an editor in hexadecimal format.
• REG_DWORD - This type represents the data by a four byte number and is commonly used for boolean values, such as "0" is disabled and "1" is enabled. Additionally many parameters for device driver and services are this type, and can be displayed in REGEDT32 in binary, hexadecimal and decimal format, or in REGEDIT in hexadecimal and decimal format.
• REG_EXPAND_SZ - This type is an expandable data string that is string containing a variable to be replaced when called by an application. For example, for the following value, the string "%SystemRoot%" will replaced by the actual location of the directory containing the Windows NT system files. (This type is only available using an advanced registry editor such as REGEDT32)
• REG_MULTI_SZ - This type is a multiple string used to represent values that contain lists or multiple values, each entry is separated by a NULL character. (This type is only available using an advanced registry editor such as REGEDT32)

• REG_SZ - This type is a standard string, used to represent human readable text values.
• REG_DWORD_LITTLE_ENDIAN - A 32-bit number in little-endian format.
• REG_DWORD_BIG_ENDIAN - A 32-bit number in big-endian format.
• REG_LINK - A Unicode symbolic link. Used internally; applications should not use this type.
• REG_NONE - No defined value type.
• REG_QWORD - A 64-bit number.
• REG_QWORD_LITTLE_ENDIAN - A 64-bit number in little-endian format.
• REG_RESOURCE_LIST - A device-driver resource list.
Editing the Registry
The Registry Editor (REGEDIT.EXE) is included with most version of Windows (although you won't find it on the Start Menu) it enables you to view, search and edit the data within the Registry. There are several methods for starting the Registry Editor, the simplest is to click on the Start button, then select Run, and in the Open box type "regedit", and if the Registry Editor is installed it should now open and look like the image below.
Using Regedit to modify your Registry
Once you have started the Regedit you will notice that on the left side there is a tree with folders, and on the right the contents (values) of the currently selected folder.
Like Windows explorer, to expand a certain branch (see the structure of the registry section), click on the plus sign [+] to the left of any folder, or just double-click on the folder. To display the contents of a key (folder), just click the desired key, and look at the values listed on the right side. You can add a new key or value by selecting New from the Edit menu, or by right-clicking your mouse. And you can rename any value and almost any key with the same method used to rename files; right-click on an object and click rename, or click on it twice (slowly), or just press F2 on the keyboard. Lastly, you can delete a key or value by clicking on it, and pressing Delete on the keyboard, or by right-clicking on it, and choosing Delete.
Note: it is always a good idea to backup your registry before making any changes to it. It can be intimidating to a new user, and there is always the possibility of changing or deleting a critical setting causing you to have to reinstall the whole operating system. It's much better to be safe than sorry!

A wise administrator once said, "The more you know about the Microsoft® Windows® registry, the more dangerous you are." In a way, this is true because when you know nothing about the registry—except for the horror stories you've heard about its destructive power—you're much more careful when making changes than you'd probably be if you knew the entire registry structure inside and out. What this means is that regardless of your skill level, you can inadvertently make a change to the registry that will destroy Windows. Fortunately, there are often steps you can take to correct the action. In this article, I'll show you some techniques you can use to repair a damaged registry.
Using Safe Mode
The easiest way to fix a damaged registry is to boot Windows into Safe Mode and run REGEDIT to make the corrections. Many times this technique will work even when registry problems prevent Windows from booting in Normal Mode, because Safe Mode uses a minimal set of drivers and registry instructions. Of course, for this technique to truly work, you must know where you made the initial mistake in the registry and what needs to be changed to make the correction.
Using the Import Feature
As you may know, the Registry Editor has the ability to import and export the registry to and from a text file. You can do this by using the Import Registry File and Export Registry File commands on the Registry Editor's Registry menu. If you plan on making modifications to your registry, you can export the registry to a text file. If something were to go wrong, you could later import your original registry back in.
