On every new version of Internet Explorer I usually expect the lame (really lame) integrated download manager to be improved. What I did not expect is for it to become even worse. The "metro" version of IE10 has the worse download manager I've ever encountered. Even Internet Explorer for Windows 3.1 was far better. If you hide a current download you will not be able to un-hide it. And if you need to cancel it, the only option available is to completely shut down your internet connection.
Then you would think: don't hide the downloads. Well, it so happens that the Download Notification area does NOT shrink your browser real-state space. It displays on top of it. That means that even if you are viewing a page that is not the source of your download, you will NOT have access to any information on the bottom of the page. You have to wait for the downloads to finish to finally see the bottom of the page, unless, of course, you hide the downloads, never to see them again until they finish or fail.
And finally, no download history.
IE10 download manager is simply the crappiest ever. In fact, that one issue made me download and install Firefox on my Brand new W8 machine.
