Expanding on Johannes Rössel's answer: here's how to do the swap (assuming you are using a US keyboard and English language version of Windows)
- Click the Start button and type "keyboard language". Select "Change keyboards or other input methods".
- A "Region and Language" window will appear with the "Keyboards and Languages" tab selected. Click on the "Change keyboards..." button.
- The "Text Services and Input Languages" window will appear. On the "General" tab, in the "Installed services" section, look for "English (United States) -> Keyboard -> US". If it is there, skip ahead to step number 7
- Click the "Add..." button. The "Add Input Language" window will appear.
- Expand the "English (United States)" tree and the "Keyboard" sub-tree under it.
- Put a check mark next to the "US" option, then click "OK". Return to the "Text Services and Input Languages" window.
- In the "Default input language" section, click the drop-down menu and select, "English (United States) - US".
- In the "Installed services" section, click "United States-International" if it is listed, then click the "Remove" button. Repeat this for any other keyboards listed until only the "US" keyboard is listed.
- Click the OK button. Return to the "Region and Language" window, then click the OK button.
**Some programs will not notice this change until you reboot your computer.
P.S. to anybody who wants to up-vote this solution: Please consider up-voting Johannes' answer as well. I had this same issue once, and I would not have remembered this if it wasn't for Johannes' answer.
