  2. Next enter the following: remove-appxpackage and include the full package name.  This example would require the following remove-appxpackage RyersonUniversity.GoMobile_1.0.0.13_x64__qkhm82779sy0y - Confirm

    Note: -Confirm 
    can be added to the end of the command to provide a confirmation from the individual running the command to ensure the task is to be completed.

Once completed, the troublesome modern application has been removed.
