With Windows 8.1, putting a Web browser into full screen requires just a single key. Whether you're using Internet Explorer, Firefox or Chrome, the F11 key opens and closes full screen mode and the same commands for zooming in and out of the page apply to each browser. If you have Windows 8.1, 8.1 RT, 8.1 Pro, or 8.1 Enterprise, you also have the option to create an account with assigned access, forcing Internet Explorer into full-screen mode. Sometimes called "kiosk mode," assigned access can be ideal if other people (particularly people you don't know or children) will be using the computer. When logged into this account, users can't make the browser window smaller or access any other apps.
Full Screen and Zoom Shortcuts
Launch Internet Explorer, Firefox or Chrome. Press the F11 key to put the browser into full-screen mode. The Web page fits the entire screen. Press the F11 key at any time to exit full-screen mode.

Press the "Ctrl" and "0" (zero) key at the same time to return to the page size to normal.
Lock a Browser in Full-Screen Mode
Make sure you are logged in with an administrator account on Windows 8.1 RT, Pro, or Enterprise. This will not work on Windows 8.1 standard version.
Move the cursor to the bottom right corner of the screen and move it up, then select "Settings." Click "Change PC Settings" and then "Accounts."
Click the "Add Account" option and then click the "Sign in Without a Microsoft Account (Not Recommended)" option. This is going to be a limited account so a Microsoft Account isn't necessary in this case. Select "Local Account."
Enter a username like "Kiosk" and select a password as instructed on the screen.
Log out of Windows and log in with the new Kiosk account. Log back out again. This step ensures the new account gets created correctly. Log back in with your administrator account.
Navigate through Settings, Change PC Settings and Accounts once again. The new Kiosk account is now listed. Click the "Set Up an Account For Assigned Access" link.
Select "Choose an Account," then click the "Kiosk" account.
Select "Choose an App" and select "Internet Explorer." When you log in with the new Kiosk user account, it will automatically open Internet Explorer in full-screen mode. Users cannot exit Internet Explorer or exit full-screen mode. To log out of Kiosk mode, press the Windows key five times and then log in with your normal Windows account.
