How to backup and restore specific Registry keys on Windows 11

The Registry is an essential database for the proper functioning of Windows 11, as it stores configuration settings and options for the system and apps. Since it contains information about hardware devices, applications, user preferences, and system settings, any misconfiguration can cause irreversible damage to the current setup. As a result, it's never a good idea to change its settings. 

However, when you must modify the Registry for a particular reason, you can create a backup of the specific key (or set of keys) instead of backing up the entire database or system.

Furthermore, the ability to export and import parts of the Registry can come in handy when you have to apply the same configuration to other devices running the same version of the operating system.

This how-to guide will walk you through the steps to back up and restore Registry keys on Windows 11.

• Quick note: You can export keys like folders, DWORDs, and Strings. If you choose a folder, everything within that location will be backed up.

6. Select the location to back up the key.
7. Confirm a descriptive name for the ".reg" backup file.
8. Choose the Selected branch option.

9. Click the Save button.

Once you complete the steps, the settings will be exported into a ".reg" file, which you can use to undo changes or replicate the same configuration on another computer.

7. Click the OK button.

After you complete the steps, the contents of the file will merge into the database. Usually, the Registry changes will apply immediately, but in some cases, you may need to restart the computer.

Although the import process can help you restore previous settings, this option won't change any additional settings you may have configured after exporting the keys into the ".reg" file. 

In other words, if you created a backup of a specific DWORD key and added another DWORD or String to the Registry, the import process will only affect the settings you exported in the backup. If you also have to remove other settings, you will have to select and delete each of the keys individually.
