If you previously chose to register using any one of the following methods, you cannot change your registration method at a later time.
- E-mail
- Internal fax
- External fax or Postal Mail
When you use one of the above three methods, you subsequently receive a confirmation number back from Microsoft. Until you enter that confirmation number in the ORW, you will be prompted for it each time you start one of the Office programs. The ORW does not have the ability to change registration methods after you have submitted your information.
