Open REG File

These are registry entry files, that's where their acronyms come from.

REG files are simple applications that, when executed, add instructions or modify keys or values ??in the Windows Registry.

Basically, REG extension files consist of plain text files, which contain keys or entries and are saved with the .REG file extension, which when executed, after a confirmation message, Windows adds the values ??they contain to the Registry.

Windows' register

The Registry is a kind of database with Windows settings and many of the installed programs.

With these REG files, we can easily and quickly make changes to the operating system's structure, preferences, and application behavior.

REG files and Windows security

Over time, it has been shown that malicious programs can make changes to the structure of the operating system, making use of the registry, with REG files.

Therefore, we must be sure of the source where a REG file comes from, since we could be putting the security and stability of our operating system at risk.

Create a REG file

Registry entry files can be created in two ways.

Manually, by editing a plain text file, adding the necessary values ??and changing the default extension from TXT to REG.

Exporting a key, from the Regedit registry editing tool.

Software to open and work with a REG file

REG files are executable and you only need to double-click on it to make it work.

The most common application for a REG file is to update the Windows Registry.

In other words, the REG file, in Windows, is an executable file that, when you double click on it, an update of the registry is executed.

  2. Select the section of the registry that you are interested in modifying

Open a REG file

Because REG files store the registration key, serial number, and other user registration information for a particular program, certain precautions must be taken when manually opening that file.

It is IMPORTANT to know that the process of updating the Windows registry is an advanced process and that it is usually delicate, therefore, it should be done if you know exactly what you are doing.
