How do I delete a Registry key or value?

Deleting a Registry key or value is done by using the Windows Registry Editor tool. To delete a key or value, follow these steps:

1. Open the Windows Registry Editor by typing “regedit” into the Run command box.

2. Navigate to the key or value you want to delete. You can do this by expanding the folders in the left-hand pane.

3. Once you have located the key or value, right-click on it and select “Delete” from the drop-down menu.

4. In the Confirm Key Delete dialog box, click “Yes” to confirm that you want to delete the key or value.

5. The key or value will now be deleted.

It is important to note that deleting something from the registry is an irreversible action. If you are unsure of what you are doing and delete a key or value, it could cause your computer to malfunction or cause other software to become inoperable. Therefore, it is important to always back up your registry prior to making any changes.

Note: Deleting a key or value is different than disabling it. Disabling a registry key or value does not remove it from the registry; instead, it simply prevents it from being used. To disable a key or value, you must change its permissions to deny access.
