Now I know why M$ removed most of the Add Ons ect. from the Internet Explorer Gallery when I installed Win 10 and looked for my favorite Add Ons the cupboard is almost bare (so to speak) and the US one had pages and pages, now you have to use the search box just to find the Google Search, Maps & Translate Add Ons.
