Step-by-Step Instructions
Accessing Regedit

Creating a Registry Backup

- Always make a fresh backup of the entire Registry before making any edits.




- Ensure you save the backup in a location that you can easily access later.

- If you're only backing up a portion of the registry, set the range to 'Selected branch' and confirm the field contains the correct key(s).
Exploring the Registry

- If the Computer icon already shows several folders below it, it's already expanded.

- HKEY_CLASSES_ROOT - The most intricate of the Registry's five primary folders, it contains numerous applications responsible for opening or reading various file types.
- HKEY_CURRENT_USER - This folder holds user-specific information, such as personal folders and Control Panel settings.
- HKEY_LOCAL_MACHINE - Here, you'll find information that applies to all users on the computer, including driver and operating system settings.
- HKEY_USERS - Within this folder, you'll find the same information as in HKEY_CURRENT_USER, along with data for all other users on the computer.
- HKEY_CURRENT_CONFIG - This folder stores the current configuration of your computer, which is also found in HKEY_LOCAL_MACHINE, along with any other configurations present on your system.

- For instance, clicking on the HKEY_CURRENT_USER folder should display at least one icon on the right side of the page labeled (Default).

- You can also double-click on folders to expand them.
