Keyboard Typing Wrong Characters Windows [Fix]

It can be extremely frustrating when your keyboard suddenly starts typing the wrong characters on your Windows PC. You may press one key and see another letter, symbol, or number appear on the screen. In some cases, the keyboard may type shortcuts automatically, switch languages unexpectedly, or enter symbols instead of normal letters.

This issue is common on both Windows 11 and Windows 10, and it can happen because of incorrect keyboard layouts, Num Lock settings, outdated drivers, language changes, stuck modifier keys, or hardware problems. 

In this guide, you will learn several methods to fix a keyboard that types the wrong characters in Windows. 

Keyboard Typing the Wrong Characters Windows 11/10 [Fix]

If your keyboard is typing the wrong characters in Windows 11 or Windows 10, first check whether the correct keyboard layout and language are selected. Then disable Num Lock, run the Keyboard Troubleshooter, update or reinstall the keyboard driver, and check for stuck modifier keys like Shift or Alt. Restarting the computer and reconnecting the keyboard can also help resolve the issue.

Why Is Your Keyboard Typing the Wrong Characters?

Before jumping into the fixes, it helps to understand what usually causes this problem. In many situations, the keyboard itself is completely fine. Instead, Windows settings or software changes are responsible.

Some common causes include:

• An incorrect keyboard layout was selected in Windows
• Num Lock accidentally enabled on laptops
• Sticky Keys or other accessibility features are interfering with typing
• Outdated or corrupted keyboard drivers
• Dust, debris, or hardware damage affecting keys
• Language settings are changing automatically
• External keyboards with regional layouts different from Windows settings

Now let’s go through the solutions one by one.

Step 1: Restart Your Computer

Sometimes the easiest fix is also the most effective. A temporary software glitch can cause your keyboard to behave strangely. Restarting Windows refreshes system services and clears minor bugs.

To restart your PC, go to Start > Power > Restart.

After the computer restarts, test your keyboard in a simple application like Notepad. Type several letters, numbers, and symbols to check whether the issue is gone.

If the keyboard still types incorrect characters, continue with the next method.

Step 2: Check the Keyboard Language and Layout

One of the most common reasons for wrong characters is an incorrect keyboard layout. For example, Windows may accidentally switch from a US keyboard layout to another regional layout.

When this happens, symbols and keys may no longer match what is printed on your keyboard.

To check your keyboard layout in Windows 11, go to: Start > Settings > Time & Language > Language & Region

Under the Preferred Languages section, select your language and click the three dots next to it. Then choose Language Options.

Under the Keyboards section, verify that the correct keyboard layout is installed. If you use a standard US keyboard, select US QWERTY or English (United States).

If you see an unfamiliar layout, remove it by selecting it and clicking Remove.

In Windows 10, go to: Start > Settings > Time & Language > Language

Select your language and click Options to manage keyboard layouts.

After making changes, restart your computer and test the keyboard again.

Step 3: Turn Off Num Lock

Laptop keyboards often use shared keys for letters and numbers. When Num Lock is enabled, some letter keys may type numbers instead.

For example:

• U may type 4
• I may type 5
• O may type 6
• J may type 1
• K may type 2

To fix this, locate the Num Lock key on your keyboard. It may appear as:

• NumLock
• Num LK
• NmLk

On many laptops, you may need to press: Fn + Num Lock

Once Num Lock is disabled, try typing again.

If you are unsure whether Num Lock is active, open Notepad and test the affected keys.

Step 4: Disable Sticky Keys and Filter Keys

Windows accessibility features like Sticky Keys and Filter Keys can sometimes interfere with normal typing behavior.

These features are designed to help users with mobility needs, but they may accidentally activate keyboard shortcuts or delay key presses.

To disable these features in Windows 11, go to: Start > Settings > Accessibility > Keyboard

Turn off the following options:

• Sticky Keys
• Filter Keys
• Toggle Keys

In Windows 10, go to: Start > Settings > Ease of Access > Keyboard

Disable the same settings.

After turning them off, restart your PC and test the keyboard.

Step 5: Run the Windows Keyboard Troubleshooter

Windows includes built-in troubleshooters that can automatically detect and repair keyboard-related problems.

• In Windows 11, go to: Start > Settings > System > Troubleshoot > Other Troubleshooters
• Find Keyboard and click Run.
• In Windows 10, go to: Start > Settings > Update & Security > Troubleshoot > Additional Troubleshooters
• Select Keyboard and click Run the Troubleshooter.

Follow the on-screen instructions carefully. Windows may automatically apply fixes if it detects a problem.

Once the process is complete, restart your computer.

Step 6: Update the Keyboard Driver

A corrupted or outdated keyboard driver can cause incorrect typing behavior. Updating the driver can often solve the issue.

• To update the keyboard driver, press Windows + X.
• Then select Device Manager.
• In Device Manager, expand the Keyboards category.
• Right-click your keyboard device and select Update Driver.
• Choose: Search automatically for drivers

Windows will search for the latest compatible driver and install it if available.

After the installation finishes, restart your PC and test the keyboard again.

Step 7: Reinstall the Keyboard Driver

If updating the driver does not help, reinstalling it may fix corrupted driver files.

• Open Device Manager again by going to: Windows + X > Device Manager
• Expand the Keyboards section.
• Right-click your keyboard and select Uninstall Device.
• Confirm the removal if prompted.

After uninstalling, restart your computer. Windows will automatically reinstall the keyboard driver during startup.

Once Windows loads again, test the keyboard.

Step 8: Check for Stuck Shift, Alt, or Ctrl Keys

Sometimes modifier keys like Shift, Alt, or Ctrl become stuck physically or electronically. This can cause your keyboard to type symbols or unexpected characters.

For example:

• Holding Shift changes letters to uppercase
• Alt Gr can type special symbols
• Ctrl shortcuts may trigger commands

Press each modifier key several times to ensure they are not stuck.

You should also inspect the keyboard for dirt, crumbs, or debris around the keys.

If you use an external keyboard, disconnect it and reconnect it securely.

For wireless keyboards, replace the batteries and reconnect the Bluetooth or USB receiver.

Step 9: Test the Keyboard in Another Application

Sometimes the issue is limited to one specific application instead of Windows itself.

Open different programs such as:

• Notepad
• Microsoft Word
• Your web browser
• Search box in Windows
• Type several characters in each app.

If the keyboard works normally in some applications but not others, the issue may be related to that software rather than your keyboard.

In this situation, updating or reinstalling the affected application may help.

Step 10: Check for Windows Updates

Microsoft regularly releases updates that fix bugs, compatibility problems, and driver issues.

• Installing the latest updates may solve your keyboard problem.
• In Windows 11, go to: Start > Settings > Windows Update
• Click Check for Updates.
• In Windows 10, go to: Start > Settings > Update & Security > Windows Update
• Select Check for Updates.

Download and install any available updates, then restart your PC.

Step 11: Try an External Keyboard

If you are using a laptop keyboard, connecting an external USB keyboard can help determine whether the problem is hardware-related.

Plug in a USB keyboard and test it in Notepad.

If the external keyboard works properly, the built-in laptop keyboard may be damaged or malfunctioning.

Possible causes include:

• Liquid damage
• Dust buildup
• Worn-out keys
• Loose internal keyboard connection

In this case, professional repair or keyboard replacement may be necessary.

Step 12: Scan for Malware

Malware and unwanted software can occasionally interfere with keyboard input or system settings.

Running a security scan can help identify hidden problems.

To run a Windows Security scan in Windows 11 or Windows 10, go to:

Start > Settings > Privacy & Security > Windows Security > Virus & Threat Protection

Click Quick Scan.

You can also choose Full Scan for a more detailed inspection.

After the scan finishes, restart your computer.

Step 13: Perform a Clean Boot

A background application or startup program may conflict with your keyboard.

A clean boot starts Windows with only essential services.

• Press: Windows + R
• Type: msconfig
• Then press Enter.
• Go to the Services tab.
• Check the box for: Hide all Microsoft services
• Then click Disable all.
• Next, go to the Startup tab and select Open Task Manager.
• Disable unnecessary startup applications.
• Restart your computer and test the keyboard again.

If the problem disappears, one of the disabled programs was causing the issue.
