Sir, not INTERNET EXPLORER.
Microsoft explorer, it's the thing that makes all your icons and taskbar show up and stuff.
If you want to see, do CTRL + ALT + DELETE and delete the explorer.exe process. If you want to bring it back after, do ctrl+alt+delete again and press "run program" and just type in explorer.exe.
I downloaded it from some forum from megaupload and stuff.
Program i used was mkvtoolnix
