Hello Dentoz, and welcome to Seven Forums.
It sounds like you may have more than one website (ex: Internet Explorer Gallery) set as your home pages. Double check using the tutorial below to see if you have more than one home page set for IE. If you do, then you could remove any that you don't want to open as your home page(s).
Internet Explorer Home Page - Add or Change
The Internet Explorer Gallery
is a Microsoft website that helps you to personalize your Internet Explorer for how you access your favorite content and services by providing pinned sites, add-ons, and tracking protection lists to download and install.
Hope this helps,
