Go to your desktop. Make sure no programs are on/open in the taskbar. You also want to hide the clock on the taskbar for this prank. And move your mouse out of the screen. Good. Now click on your keyboard PrtScnSysRq. It’s top right corner of your keyboard. This will take a picture of your desktop. Go to paint and press Ctrl+v to paste in the picture. Save it.
Now, go back to your desktop and right-click anywhere you want and select (if you’re on xp) Arrange Icons By and then Show Desktop Icons. This option was already checked, so when you click it again it will be unchecked.
For Vista users, right-click and select View, and then Show Desktop Icons. You may also select Show Widgets if you took your picture with Widgets in the first place. This will also uncheck them.
DONT WORRY YOU CAN ALWAYS GO BACK AND CHECK THEM.
Then go down(or up) to your taskbar and right-click it and select Lock taskbar. This will already be checked so when you click it, it will be un-checked.

Then right-click it again and click on properties.
Then select Auto-hide the taskbar.

So when your mouse isnt on the taskbar, the taskbart will go down. You can get it back by moving your mouse over it.
Almost done! Right-click the desktop and select properties. Go to change the desktop wallpaper with the picture you saved of the desktop before. Click apply and ok.
When you’re friend will go on he wont be able to click on any programs or anything. It will look like it is frozen. But if he/she moves his/hers mouse down the task bar will come pop up. Also good thing you hid the clock too in the first place otherwise the victim could see that its 19:04 for the past 10 minutes
That’s it!
