Unregister by using the Subscription Manager user interface

You can unregister a RHEL system from Red Hat Subscription Management Server by using the Subscription Manager user interface.

Procedure

  1. Log in to your system.
  2. From the top left-hand side of the window, click Activities.
  3. From the menu options, click the Show Applications icon.
  4. Click the Settings icon, or enter Settings Manager in the search.
  5. In the left side column, select the System options, then on the new screen select Registration.

    The Registration screen displays the current status of your Subscription.

  6. Click the Remove Registration… button and confirm your choice.
  7. Enter your administrator password in the Authentication Required dialog box. The system is unregistered from the Subscription Management Server, and the status System Not Registered is displayed with the Register System… button enabled.

    To continue uninterrupted services, re-register the system with either of the management services. If you do not register the system with a management service, you may fail to receive the system updates.
