Setting Up a Secure System
and restart the system to check out its diagnostics and fi nd out what kind of computer it
is. It’s a geek thing, but all geeks do it.
You will doubtless encounter such geeks wherever you set up your presentation, but espe-
cially at trade shows and conventions. (We geeks love trade shows and conventions.) Your
mission is to prevent them from stopping your presentation.
The best way to prevent someone from tinkering with your presentation is to get the input
devices out of sight. Hide the CPU (the main box of the computer), the keyboard, and
the mouse. If the PC uses USB for keyboard and mouse, you can safely disconnect them
while the computer is running; with older-style keyboard and mouse connectors, you can’t
because an error message appears when you do so that interferes with the show. If you
must keep the keyboard or mouse connected, don’t cover them with anything that might
restrict the airfl ow or you might end up with an overheated PC. You can also set up the fol-
lowing security measures in your presentation fi le:
On the Slide Show tab, click Set Up Slide Show and make sure you have chosen
Browsed at a Kiosk. This disables the ability to advance the presentation on mouse
click while the slide show is running. The only way to stop the show will be to use
the keyboard. This works best for self-running shows where the slides advance
automatically.
If you make the keyboard available for user navigation, the Esc key will also be available for stopping the program. A
utility is available that disables the Esc key at www.mvps.org/skp/noesc.htm .
Show the presentation using the PowerPoint Viewer program rather than
PowerPoint itself. That way nobody can access PowerPoint and create a new presen-
tation to show. For further security, remove the PowerPoint application completely
from the PC on which the presentation is showing. The PowerPoint Viewer does
not come with PowerPoint 2013, but it can be downloaded for free. Go to http://
office.microsoft.com an d search for PowerPoint Viewer. Set a startup pass-
word for your PC so that if people manage to reboot it, they won’t get into your PC
to tamper with its settings. This is usually set through the BIOS setup program. If
you can’t do that, set a Windows startup password for each of the user accounts.
(Do that through User Accounts in Control Panel in Windows.)

Assign a password to a PowerPoint fi le, as you learned in Chapter 2, “Creating and
Saving Presentation Files,” to prevent it from being opened, modifi ed, or both.
Although this will not prevent a running presentation from being stopped, it will at
least prevent it from being altered or deleted. However, if it is already open, hack-
ers will have full access to it, and if you set it to have a password only for modifi ca-
tions, a hacker could save it under a different name, make changes, and then run
the changed version.
