Please tell me you know nothing about the Windows Registry without telling me you know nothing about the Windows Registry.
In case the snark by itself isn't useful: Windows provides the Registry Editor which, as its name implies, lets you modify the Registry using a GUI.
If you prefer a text-based method, you can modify the Registry by loading in human readable (and editable) .reg plain text files.
Powershell also provides a CLI environment, if that is preferred.
