What is a .reg file?

A .reg file is a text-based file format used by Microsoft Windows to store and import registry settings. The Windows Registry is a hierarchical database that stores low-level settings for the operating system and applications. These settings control how Windows looks and behaves, and how applications interact with the system. A .reg file contains a series of registry keys and values, organized in a specific syntax. When a .reg file is executed (typically by double-clicking), the settings it contains are merged into the Windows Registry, modifying the system's configuration. This allows users to easily back up, restore, or share registry settings. Reg files are often used to apply tweaks, fix problems, or customize the Windows environment. They can be created manually using a text editor or exported from the Registry Editor (regedit.exe). Be cautious when running .reg files from untrusted sources, as they can potentially make unwanted or harmful changes to your system.
