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.

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.

Registry entry files can be created in two ways.
