Fix: Keyboard typing wrong letters on Windows 10

Some Windows 10 users have reported a weird problem where their keyboard is typing the wrong characters. The issue is certainly peculiar since a lot of users report it on brand new computers and keyboards.

Affected users report that typing up a character will output another. For example, one user reports that pressing the Q key outputs Q0 or M while pressing M outputs @.

After investigating the issue, we managed to observe that the most common culprit is a glitched Standard PS/2 Keyboard. However, there are occurrences where affected users discovered that the default output language or AutoCorrect was causing this behavior.

If you’re currently struggling with the same issue, this article will provide you with some troubleshooting steps. Below you have a collection of methods that other users in a similar situation have used to resolve the issue. Please follow each potential fix in order until you find a method that takes care of the Keyboard typing wrong characters on Windows 10 error. Let’s begin!

Prerequisites

Before we start with the actual troubleshooting guides, let’s get a few obvious things out of the way.

For starters, if the keyboard is only outputting one character regardless of which key you press, verify whether that particular key is stuck. If it is, unstuck it and see if the issue is resolved.

Another potential problem causer is the FN + Numlock combo on laptops. Some laptop keyboard will behave erratically when NumLock is turned on. Disable NumLock by pressing Fn + the Numlock key on your laptop and see if the issue persists. You can also try to press Ctrl + Shift to see if you’ve not accidentally toggled a scrambled keyboard.

Next, see whether your USB port is acting up (if applicable) by connecting your keyboard to a different USB port and seeing if the issue repeats.

And finally, connect a spare keyboard and connect it to the machine that is experiencing the keyboard typing the wrong characters. If you don’t see the same behavior with this keyboard, there’s a strong chance that the keyboard itself is broken and the issue is not caused by a conflict or internal driver.

Method 1: Changing the language

Different languages have different input keys. The reason why your keyboard is outputting the wrong characters might be because you have the wrong input language set up as the first choice.

Some users have managed to resolve the issue by changing the default input language to their preferred language. Here’s a quick guide on how to do this and resolve the keyboard typing the wrong characters issue:

  1. Press Windows key + R to open up a Run box. Next, type “ms-settings:regionlanguage” and hit Enter to open the Region & Language tab of the Settings app.
  2. In the Region & language tab, scroll down to Preferred languages  (under Languages) and use the arrow icons to boost your preferred input language to the top spot.
  3. Once your preferred language is on the top spot, reboot your computer enforce the changes and see if the keyboard typing the wrong characters has been resolved at the next startup.

Method 4: Disabling or modifying AutoCorrect settings

If the issue is only occurring in Microsoft Word, it is very likely that this behavior is caused by AutoCorrect. Some users have reported managing to fix the keyboard typing the wrong characters issue after discovering the AutoCorrect was altering the inputted characters in Word.

Here’s a quick guide on how to check whether an AutoCorrect option is causing this behavior and correct it if necessary:

  1. Open Microsoft Word.
  2. Use the ribbon at the top to click on File > Options.
  3. In the Word Options menu, expand the Proofing tab and click the AutoCorrect Options button.
  4. Start looking for any entries that might convert your inputted into other characters.
  5. Once you do the required modifications, hit Ok to save the changes and restart Word to see if the issue has been eliminated.
