How To Restore Registry Keys in Windows 7

If you've backed up a registry key in Windows 7, or even if you've backed up the entire registry, you'll be happy to know that restoring it is very easy.

Maybe you're seeing problems after a registry key change or the issue you were trying to correct wasn't resolved by your recent Windows Registry edit.

Either way, you were proactive and exported a registration file just in case something happened.


Follow these steps to restore previously exported subkeys to the Windows 7 Registry.
Note: The steps below require working with the Windows Registry. Making changes other than the ones described below could cause serious problems.

1. Locate the Registration File you exported before making your changes to the Windows 7 Registry.
   Having trouble locating the file? Assuming you actually did make an export from the registry, look for a file ending in the REG file extension. Check your Desktop, in your Documents folder, and in your C:\ drive.
   
   
2. Double-click on the REG file to open it.
   
3. Next you'll be prompted with a message in a Registry Editor window:
   Adding information can unintentionally change or delete values and cause components to stop working correctly. If you do not trust the source of this information in [REG file location], do not add it to the registry. Are you sure you want to continue?
   
   
4. Click the Yes button.
   Important: This isn't a message to be taken lightly. If you're importing a REG file that you did not export or one you downloaded from a source you can't trust, be aware that you could cause considerable damage to Windows 7 (depending on the registry keys being changed).
   
   
5. Assuming the registry key(s) import was successful, you should receive the following message in a Registry Editor window:
   The keys and values contained in [REG file location] have been successfully added to the registry.
   
   
6. Click the OK button in this window.
   The registry keys contained in the REG file have now been added to the Windows 7 Registry. If you know where the registry keys were located, you can open Registry Editor and verify that the changes were made as you expected.
   
   
7. Restart your computer. Depending on the changes that were made by importing the registry keys, you may need to restart to see the changes take effect in Windows 7 or in your programs.
