How to Always Load Internet Explorer 9 in Full Screen Mode


Internet Explorer 9 has a minimal interface by default, with the tab bar and the toolbar and address bar on the same line. However, you can gain even more viewable space by pressing F11 to go to full screen mode.

If you like full screen mode and want to use it most of the time, you can have Internet Explorer open in that mode automatically, by editing a setting in the registry. To begin, enter “regedit” (without the quotes) in the Search box on the Start menu. When the results display, click regedit.exe or press Enter when it’s highlighted.

NOTE: Before making changes to the registry, be sure you back it up. We also recommend creating a restore point you can use to restore your system if something goes wrong.


If the User Account Control dialog box displays, click Yes to continue.

NOTE: You may not see this dialog box, depending on your User Account Control settings.


Navigate to the following key in the tree on the left.

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main

Double-click on the FullScreen item on the right.


Change the Value data to “yes” (without the quotes) and click OK.


Close the Registry Editor by selecting Exit from the File menu.


Now, Internet Explorer will always open in full screen mode. Remember, you can turn full screen mode on and off by pressing F11.

    Why would a user add a registry entry, when a simply right click, properties, run maximized is the standard method for changing the default window size?

    @jasray: Because some web site told him to.

  3. Lelouch

    @jasray: Because that’s maximized. NOT full screen.

    The other option is to go the whole hog and download the windows 8 release preview. It comes with IE10 which runs full screen anyway, and as an added bonus, has far better support for HTML5 and CSS3

    Why would you even use IE

    @jasray: As Lelouch said, you aren’t talking about the same thing, but also, because it’s just cool to know about options/settings that aren’t readily visible on the surface!

    @Rutger: because it’s fast- and improved a lot in IE9.

    There’s no need to edit the registry to always open IE 9 in full screen mode.

    Here’s another way to open IE in full screen mode everytime you open IE 9 without touching the registry at all. Open IE 9, Press F11 and then close IE 9. Now everytime you open IE 9 it open in full screen mode.

    Ooops! Full versus Maximized–got it. Soory/thanks Lori. Then Allan has a simple fix. Thanks Allan.
