You will need to stop using IE as your browser, it is no longer supported. Microsoft installed an update that whenever you open IE, that it would open Edge instead. Change your default browser to either Firefox or Chrome or something else.
Windows 10 or later. However, there was an update awhile back that made IE open the Edge browser instead. Windows 7 can still use IE but its not recommended, also not recommended to have windows 7 when windows 10 upgrade is still free.
