By default the new Netflix application remembers a users login information for use each time you enter the movie browser. However, what if you should change your username or password via the Netflix website? Unfortunately at this point instead of allowing you to re-enter your information the Netflix app simply returns a login error and sends you back to the start menu. In order to re-enter our login information and once again be able to login to the Netflix app we need to clear the registry entries containing the login information.
To get started we need to launch the Windows Registry Editor by opening the start menu and enter “regedit” into the search box and press enter. A dialog will appear asking you to confirm, since the program needs administrator privileges to run. Once inside you’ll see a folder style listing on the left and a few entries on the right. In the left hand pane navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Media Center\Extensions\Netflix.
Delete the Netflix folder or just the entries on the right hand side to erase the saved login information and once again be able to re-enter your login information. Just relaunch Windows 7 Media Center and enter the Netflix application and you should once again receive the login prompt.
For those not comfortable with editing the registry we’ve got a registry file available for download right here. Just download the .reg file and double-click to run then confirm that you’d like to apply the changes to your registry. Afterward re-launch Windows 7 Media Center and you should be presented with the login screen next time you enter the Netflix application.
