Types Of Information In The Registry

AccessData Registry Viewer is capable of accessing and decrypting the subkeys in an offline manner (AccessData, 2005b). Registry Editor only shows the logical structure of the registry.

Needless to say, it’s an integral and delicate component of your operating system. All the entries, referred to as keys and subkeys, are sorted into five major categories known as hives. The Windows registry is a database used to store important settings and configuration information for Windows operating systems without which Windows cannot operate.

For example, .NET Framework applications use XML files for configuration, while portable applications usually keep their configuration files with their executables. On disk, the Windows Registry isn’t simply one large file but a set of discrete files called hives. Microsoft introduced the registry back in Windows 3.1, but it was initially used only for certain types of software.

In the Windows 3.1 era, Windows applications frequently stored settings in .INI configuration files that were scattered across the OS. The registry can now be used by all programs, and it helps bring together the settings that would otherwise be scattered in many different locations across the disk. The Windows registry is exactly as it sounds—a central registry. It contains all the configuration settings for the operating system, hardware, user profiles, and software.

Inside a hive file, data stored as part of the hive is organized into containers called cells. A cell might contain a key, a value, a security descriptor (a.k.a. SID) or a list of subkeys or key values. The first element in each cell is a field that identifies its datatype, which is then followed by one or more values of that type. Any vacant space after the cell up to that boundary is free space that the registry configuration manager can allocate for other cells as needs dictate. Thus, any given block in a hive file consists of a collection of blocks, each of which contains a bin, with one or more cells inside the bin, along with empty space among the cells that make up its contents.

Windows Registry

  • Not all applications stick strictly to this recommendation.
  • They have names and can contain one or more bits of configuration data.

  • Each group of configuration data in the Registry is called a key.
  • In the right-hand pane, you see all the configuration data for the key that's selected in the left pane.

The Registry Editor allows you to view all keys and values that are in the registry, as well as change Windows, program, or driver values you feel are necessary. Although .ini files are still sometimes used, most Windows programs rely on settings made to the Windows registry after being installed.

Protected Storage is a service used by Microsoft products to provide a secure area to store private information (Carvey, 2004). Information that could be stored in Protected Storage includes MSN Explorer and Internet Explorer AutoComplete strings and passwords, Microsoft Outlook and Outlook Express accounts’ passwords, and MSN Messenger password. Registry Editor hides these registry keys from users viewing, including administrator. There are tools that allow examiner to view the decrypted Protected Storage on a live system, such as Protected Storage PassView (NirSoft, 2004) and PStoreView (PStoreView, 2005).

When introduced with Windows 3.1, the Windows Registry primarily stored configuration information for COM-based components. Windows 95 and Windows NT extended its use to rationalise and centralise the information in the profusion of INI files, which held the configurations for individual programs, and were stored at various locations. It is not a requirement for Windows applications to use the Windows Registry.

Differences Between The Win95 And Win98 Registry

The registry contains information and settings for all the hardware, software, users, and preferences of your computer and your operating system.

To view and make changes to the Windows registry, the Windows Registry Editor (shown below) may be used. In Windows 3.x, the Registry Editor was known as the Registration Info Editor or Registration Editor.
