There are a couple reasons for this. There were two different process graphics. There was the bar at the top for system process and the pop-up for process...process...you know what I mean. All processes are combined and condensed in that bottom flyout. You can pin it to be always open if you always want to see what is going on. As far as the trashcan, it is down there too. Way back in the day, having a trashcan icon in the lower right wasn't that big of a deal because the displays were so small. Dragging and dropping was quick and easy. But now with the bigger monitors, there is a lot of real estate to cover from the left tile list to the right. As MacTech54 pointed out, hitting delete is now the preferred method of clearing a tile. There is also a new and maybe better way to clear the process tile list. There is now a "Clear" button right above it. This will clear the contents of the process tile list.Attachment 384770
