If your keyboard isn’t typing the correct characters, you may have the incorrect input language selected. Modern operating systems come with ability to type in many languages, and if you have multiple languages enabled it’s really easy to accidentally switch between them. If you’re using a laptop without a number pad, your NumLock key may be the culprit.
Check the NumLock key. Many laptops will convert a good chunk of the keyboard into a number pad if NumLock is enabled. Press NumLock or Fn + NumLock to make sure that it is disabled. Try typing again to see if your keys are fixed.  If this doesn’t fix your problem, you may have the wrong language selected. Click the link below that matches your operating system:

- Windows 8 and 8.1
- Windows 7 and earlier
