First Things First

Before trying anything, make sure your system has been updated to the latest Windows version. It’s possible that the reversed Caps Lock problem was brought about by a bug, so updating your PC could easily fix that.

If there are no new updates, you can do a system restart. It’s a simple gesture that may restore normal functionality to your Caps Lock key.

Additionally, the DISM and SFC built-in utilities may be able to help if the problem is the result of system issues or corrupt data on your PC. Running DISM and SFC is easy, but you’ll need to open Command Prompt by typing “CMD” in Windows Search to start the process.

1. Ensure Caps Lock Isn’t Stuck

Most of the time you can tell when a key on your keyboard is stuck – but it’s not always so obvious. If you are unsure whether the Caps Lock key is truly stuck, follow the steps below to figure it out.

  1. Type “on-screen keyboard” in Windows Search.
Typing "on-screen keyboard" in Windows search.
  1. Click the Caps Lock key to activate it, then click it again to deactivate it.

  1. If the region around it is blue, it means the key is stuck.
  1. Go back to your physical keyboard and try cleaning the area around the key. You can try sliding a thin object, like a needle or cotton swab, under it and gently pushing up on it. Alternatively, you can try taking out the key entirely (not recommended for laptop users), cleaning it, then putting it back in. While holding your keyboard upside down, give it a good shake, then try repeatedly pressing the Caps Lock key to check whether it works.

2. Reconnect the Keyboard

If you’re using a desktop computer, the problem with the Caps Lock key could be due to a faulty connection. To fix this, disconnect the keyboard from the computer and plug it back in. If you’re using a Bluetooth keyboard, try pairing it again to see whether that resolves the issue.

3. Run the Keyboard Troubleshooter

The built-in Keyboard Troubleshooter may be able to assist you in resolving the reversed Caps Lock issue. Follow the steps below to try it:

  1. Open the Settings app by pressing Win + I.
  1. Select “System -> Troubleshoot.”
Accessing the "Troubleshoot" menu in System Settings.
  1. Select “Other troubleshooters.”
Clicking on "Other troubleshooters" option in System Settings.
  1. Click the “Run” button next to “Keyboard.”
Running the "Keyboard" troubleshooter in Windows.
  1. Allow the troubleshooter to scan for issues. If it finds any, it will proceed to fix them.
  2. Restart your PC to save the changes from the troubleshooting.
  3. In Windows 10, open Settings and search for “Find and fix keyboard problems.”

4. Update or Reinstall the Keyboard Drivers

Incompatible keyboard drivers could also be behind the reversed Caps Lock problems you’re seeing, so it’s important to either update or reinstall your keyboard drivers. Follow this by restarting your PC for the changes to take effect.

5. Disable Filter Keys in Accessibility

Filter keys is an accessibility feature that tells the keyboard to ignore repeated keystrokes. It aims to help people suffering from physical issues, such as hand tremors. If you’ve turned Filter keys on by mistake, it may be causing your Caps Lock to behave incorrectly. Follow these steps to turn the option off:

  1. Open Settings by pressing the Windows + I keys together.
  1. Click on “Accessibility -> Keyboard.”
"Keyboard" section under Accessibility.
  1. Turn “Filter keys” off by clicking on the toggle bar.
Togging "Filter keys" off in Accessibility.
  1. In Windows 10, go to “Settings -> Ease of Access -> Keyboard” to find the Filter keys option.

6. Turn Caps Locks Off in Word

If you’ve been using Microsoft Word, it could be possible that you’ve inadvertently turned on Caps Lock while using the program. Follow these steps to disable it.

  1. Open Microsoft Word on your PC and open a document.
  1. Right-click the status bar at the bottom.
Clicking on the status bar in Word.
  1. Make sure there’s no green checkmark next to “Caps Lock” and that it says “Off.”
  2. At the same time, you may have enabled the “All caps” option for a particular paragraph but keep typing in uppercase. To undo this, highlight the text and right-click it.
  3. Select “Font” from the context menu.
Clicking the "Font" option in context menu in Word.
  1. Under “Effects,” deselect “All caps.”
Unticking "All caps" option in Font properties.

Finally, if nothing has helped so far, you can do a system restore and return your system to a configuration when the reversed Caps Lock issues weren’t present. Note that you can only use this method if a restore point has already been created.
