It’s this time of year again when you can make your tech illiterate coevals regret they’re friends with a geek. Or if you’re smart, use the occasion to remind them that they know someone who can solve anything. Up to you. Either way, have fun!

Mess With Desktop Icons

If you’re looking for a super easy and 100% harmless way to trick someone, play with their desktop icons. First, take a screenshot The Ultimate Guide on How to Take a Screenshot The Ultimate Guide on How to Take a Screenshot Most people would think taking a screenshot was a simple and straightforward process, and that it would be much the same on every platform they encounter.

Desktop Properties

If you want to make this slightly more frustrating, change the wallpaper to the screenshot you took earlier: right-click the desktop, go to Personalize, click on Desktop Background in the lower left, and browse for the respective image.

Custom Desktop Background

The desktop will look exactly like it did before, only that none of the icons will be clickable.

Flip The Screen

In Windows, you can change the screen orientation: right-click the desktop and select Screen Resolution. Under Orientation, choose one other than the default Landscape. To turn the screen upside-down, go with Landscape (flipped). As a result, everything will be upside down.

Change Mouse Settings

You can do a lot of fun things with someone’s mouse. Search for Mouse and go into Mouse Properties. Here you can switch the primary and secondary buttons, i.e. left- and right-click funtionality, customize the pointer style, increase or decrase the pointer speed (super annoying!), or adjust the scroll speed of the mouse wheel.

Enhance Their Workspace

Maybe your friends are not foolish enough to give you direct access to their computer. In that case, attack their workspace.

Click the Change keyboards… button, then click Add, browse to English (United States), expand Keyboard, and check United States-Dvorak.

    Happy April Fool's Day. I tried the flipping the desktop trick.

    My wife hunted me down that morning and said, "We have a problem. You know those movies where the Devil is around and the cross is turned upside by itself? The desktop icons on my computer are upside down and the mouse is making the cursor work backwards!" Really? . . . ah yes -- my April Fool's joke.

    She loved it.

    Back in the old days of DOS command lines, a neat trick was to type: PROMPT $P$G FORMAT C: /Y

    This resulted in the command line reading:

    C: FORMAT C: /Y [cursor].

    Guaranteed to cause consternation.

    If you were feeling really mean, then a quick COPY CON command would add it to AUTOEXEC.BAT, so it didn't go away after a reboot..

    Good for winding up salesmen in computer shops, too.

    Combine the desktop icon, flipping screen and mouse trick. The last time i've done it, it took almost 2 hours just to get it right.

    There's an extension for Chrome called ncage that replaces all images with pictures of Nicolas Cage. It's a good SFW alternative to the one Pedro mentioned.

    I don't actually touch type - I look down at the keys- but I type pretty fast so I figure I could survive! This would be quite helpful, except I was somewhat thinking more along the lines of schoolwise pranks.

    My all-time favorite is changing the browser icon's target to a custom program that displays either spiders or a bsod screen and then shuts down the computer.

    No one opens email attachments around April 1 (esp not if you have played a prank on them before, wonder why), so you have to prepare it a few weeks in advance. The easiest is to send it as a 'legit' program (last time I did this, I said I'd made a program that runs Chrome as x64 or something), and make the installer schedule some havoc on April 1.

    Do a print screen of their desktop, save the pic as the background and disable/remove the shortcuts and/or icons. Then watch them trying to load their programmes.

    My favorite prank is installing chrome extension that makes all pages to gray, or flip only web pages, getting them to use laptop upside down. Another one is Jimmy Wales asking for founding for Wikipedia in ALL pages it really annoyed my roommates.
    I also had a script that changed every image in one Web page with naked girls. It was very good seeing they freaking out with virus in they computer, running all kind of Antivirus.
