Step 1: Remap the Keyboard
1. You must download a free application from RandyRants called SharpKeys and install it.
2. Launch the application and click the "Add" button to add a new keymap.
3. Select the key that you want to map from the column on the left and choose the key that you want o map it to from the column on the left.
4. Click "Write to registry" and either logout or restart the computer to commit the changes.
To remove this prank, just open up the Sharpkeys program again and select the keymap you created and hit the "Delete" button. Then hit Write to Registry and restart again.
