There are few more things you need to know about registry.

1. Registry consists of five sections of which HKEY_CURRENT_USER stores the settings of currently logged in user. It is recommended that you store the settings under this key. Settings are stored generally in HKEY_CURRENT_USER/Software//

2. You can store machine wide settings (applicable to all users using the computer) under HKEY_LOCAL_MACHINE key. However, read/write operations to this requires administrative rights. Your application must be running in administrator privilege to write to this key.

3. Make sure that your registry reading mechanism returns default values if it is not found in the registry as well as write the default values to registry. This way, you will never run out of setting values.

4. Registry can be edited and can be read. If you are planning to store username/password combination in registry, make sure you encrypt it before you store it. Further, to make sure that it is not used on any other computer also, you should encrypt it with some machine specific information.

Hope this helps you.
