Confirm Key Delete Message in Windows Vista

Sometimes, as part of a troubleshooting step or certain "registry hacks," you may need to delete a registry key from the Windows Vista Registry.

Assuming you know the exact location of the registry key in the Windows Registry, removing a registry key is a very easy task.

However, considering how important and sensitive the registry is, be sure to follow these instructions precisely!

Follow these easy steps to delete a registry key in the Windows Vista Registry.

Note: The steps below require working with the Windows Registry. Making changes other than the ones described below could cause system problems.

Difficulty: Easy

Time Required: Deleting Windows Registry keys in Windows Vista usually takes less than 10 minutes

Here's How:

  1. Click on Start.

  2. In the search box, type regedit and hit your Enter key. The Registry Editor program will open.

  3. Using the > icon, navigate down through the registry key branches until you reach the subkey (the folder on the left) that you're wanting to delete, or the subkey that contains the value (on the right) you're wanting to delete.

  4. Backup the registry key you're about to delete. As sure as you may be that removing this particular key or value will get you the results you're after, it's always a good idea to create a backup just in case you need to restore the information back to the Windows Registry later.

  5. If you're deleting the registry subkey, make sure it's selected on the left. If you're deleting a specific registry value, make sure it's selected on the right.

  6. With the subkey or value selected, choose Edit and then Delete from the Registry Editor menu.

  7. If you're deleting an entire subkey on the left, you'll be prompted with this Confirm Key Delete message:

    Are you sure you want to permanently delete this key and all of its subkeys?

    If you're deleting one or more individual values on the right, you'll be prompted with this Confirm Value Delete message:

    Deleting certain registry values could cause system instability. Are you sure you want to permanently delete this value?

  8. No matter the confirmation message, click on the Yes button to remove the key or value.

    Note: Changes in the Windows Vista Registry are made immediately. There are no Save or Undo options like you may be used to in other programs.

  9. Close Registry Editor.

  10. Restart your computer. Depending on the keys or values you may have removed, you may need to restart to see the changes take effect in Windows Vista or in another program.

  11. If deleting the registry key or value didn't do what you expected it to do, you can always restore the registry key using the backup you created in Step 4.
