In this article, we’ll tell you all about the Windows Registry Editor and what it’s used for<\/strong>.<\/p>\n

The Windows Registry Editor is a key part of Microsoft Windows, and yet, it’s something that very few users (or even some administrators) know anything about. The registry is essentially a database <\/strong>where Windows stores all the settings<\/strong> used by applications, hardware and even the operating system itself. Whatever configurations you might have set up in the past or might create in the future will be stored in the registry.<\/p>\n

The Windows Registry first appeared on 31 December 1994 as part of Windows 3.11 and is still used today by the latest editions of Windows, both client and server versions. Before this, the early versions of Windows and MS-DOS <\/strong>used to store configuration data in text files called configuration files (.ini)<\/strong>.<\/p>\n

Some of these files were stored in shared locations and they could be used to change the way the computer behaved for all users, preventing special settings for specific users. This meant that, to make any changes<\/strong>, you had to find the right text file and manually edit it<\/strong>. Furthermore, with all the files in the same place and no security controls, there was a significant risk of things going wrong<\/strong>.<\/p>\n

However, when the Windows Registry arrived <\/strong>all this changed. This new way of managing system settings had a number of advantages<\/strong>. It was essentially a single database <\/strong>where all settings were stored, and it had a single interface for making changes called the Registry Editor<\/strong>.<\/p>\n

The registry also allowed you to create different configurations for each user. Each time a user logs on, all the settings for their applications and systems are loaded from the registry.<\/p>\n

The structure of the database <\/strong>is essentially an inverted tree<\/strong>, which makes it easier to find the configuration key you’re looking for. However, the learning curve is not exactly a smooth one, and it might take a bit of getting used to at the beginning.<\/p>\n

The registry also has various different features <\/strong>that allow you to make partial or complete backups and even export your configuration data to another device.<\/p>\n

When we say that the Windows Registry works like a database, it’s not just because it stores data. It’s also about the way it handles operations<\/strong>. For example, it ensures the integrity <\/strong>of any inputs and uses resource blocking <\/strong>to prevent the same key being written in two different locations. It also has ACID properties<\/strong>.<\/p>\n

NOTE:<\/strong> ACID properties are what a database needs to be considered transactional – Atomicity, Consistency, Isolation and Durability.<\/em><\/p>\n

More recent versions of the Windows Registry allow transactional operations with ACID properties through the use of the Commit\/Abort function <\/strong>to either confirm or revoke <\/strong>changes.<\/p>\n

Despite the huge amount of data it stores, the Windows Registry can be broken down into three basic elements<\/strong>:<\/p>\n
