The entire Windows Registry database is stored in binary files that are not visible in text editor. These two hidden files are System.dat and User.dat. They are hidden so they can be protected from the risk of being accidentally altered.
The System.dat is composed of computer specifications and hardware configurations while User.dat on the other hand contains all user's computer specifications.
Another Windows configuration file is the Config.pol which you can find in the registry. However, this file is only optional. Accessing this file requires you to save all your operating system configurations via Config.pol then place config file to network. Afterwards whenever the user logs on to the computer the operating system will access the system specifications from the Config.pol and implement it to the user's registry.
The Windows Registry is divided in to six major root key or HKEY_Name sections. This section holds registry keys. Registry keys are very similar to a regular Windows folder. This is because each key can hold subkeys while subkeys can also hold subkeys and so and so forth, similar to the foldering system of Windows.
