Registry Database for MS Windows 2000
Tuesday, January 26th, 2010Registry is the name of Windows hierarchical database, that Windows uses to store options and configurations for a Microsoft Operating System.
The registry contains set-up for components of low-level operating systems and the applications based on that platform. Registry is used by device drivers, the kernels, SAM, user interface, services and all the third party software.
To boost computers performance, the registry also gives a method to use counters.
The Windows Registry was first launched in the market with Windows 3.1 to store important configuration information for COM-based components.
The use of registry, with the induction of Windows NT and Windows 95, was expanded to include the organization of abundant INI files for each program whose use was previously made for storing settings of configuration for programs on Windows.
Keys and values are the two basic components of the Windows registry.
Stored inside the keys are the pairs of name/data known as registry values.
The Windows API functions, querying and manipulating values of registry, get value names in a different way from the key path. They may also use handle which identify the parent key.
Although, the term is a little bit confusing, with values resembling associative arrays, wherein standard definition suggests that a key is the name portion of value.
In Windows 3, keys were devoid of containing arbitrary names/data pairs, instead they contained only one unnamed value that needs to be a string.
The biggest advantage of Registry in Microsoft Windows is that it can be edited manually with the help of regedit.exe or regedt32.exe in the Windows directory.
However, sloppy registry editing can lead to a slow XP or losses that cant be reversed. So, performing registry backups must be the priority, and the same has been advised by the software giant Microsoft and various other professionals, authors and editors of business magazines.
A straightforward implementation of the present-day registry tool surfaced in Windows 3.x operating system, dubbed as “Registration Info Editor” or simply “Registration Editor”.
This was a database of applications primarily used to edit inserted OLE objects in documents.
However, it should be remembered that both the editors have several differences.
For the first time, the two programs were merged into one by Windows XP, which adopted the traditional REGEDIT.EXE as interface and added to it the functionality of REGEDT32.EXE.
However, the distinctions do not occur with Windows XP as well as the newer versions REGEDIT.EXE being the improved editor and REGEDT32.EXE being purely a stub invoking REGEDIT.EXE.
The Registry Editor enables users to do the following functions easily:
- Loading, manipulating and unloading registry hive format files (Windows NT-based systems only)
- Setting permissions based on ACLs (Windows NT-based systems only)
- Bookmarking user-selected registry keys as Favorites
- Finding particular strings in key names, value names and value data
- Remotely editing the registry on another networked computer
Linux platform too allows for editing the registry with the assistance of an open source tool called Offline NT Password & Registry Editor.
