- The most common causes are inadvertent language changes, configuration problems, or physical keyboard failures.
- The combination of quick language adjustments, physical cleaning and diagnostic tools Windows solves most cases.
- If it persists, try another keyboard, update BIOS and search malware helps rule out complex causes.
Have you ever found yourself typing something on your computer and suddenly realize that what appears on the screen doesn't correspond to the keys you're pressing? This problem, more common than it seems in Windows, can arise for different reasons: from a simple accidental configuration to problems with hardware or software. Taking it slow and easy is the best way to get your keyboard back to normal.
Below you have a complete and practical guide with all the solutions, tips and Tricks to fix a keyboard that types incorrect characters in Windows. Identify quickly identify the source of the problem and remedy it once and for all, allowing you to write normally again without complications.
Most common causes of keyboard typing incorrect characters in Windows
When the keyboard stops working properly and you see Symbols or wrong letters, the cause is usually one of the following:
- Unintentional change of language or keyboard layout: Sometimes, installed languages (for example, from Spanish to English) are switched by mistake, causing symbols such as ñ or accents to not work as they should.
- Regional or input configuration problems: Windows may associate a different language or layout with your physical keyboard by default, causing confusion.
- Keyboard shortcuts accidental: : Combinations like Alt + Shift or Ctrl + Shift change the keyboard layout or language without you realizing it.
- Hardware errors: If only certain keys fail, it could be due to dirt, wear, loose connections, or even liquid damage.
- Outdated or faulty drivers: A failure in the keyboard software or its drivers can cause this behavior.
- Malware and malicious software: Certain viruses can modify the keyboard's behavior, sending inappropriate characters.
- Problems with wireless devices: A poor Bluetooth connection or interference may cause writing failures.
Recognizing the exact cause is essential to selecting the most effective solution.
Quick and easy configuration solutions
Always start with the simplest and most effective methods. Many keyboard problems can be fixed in seconds with these steps:
- Use keyboard shortcuts to change the language: press Alt+Shift to switch between the configured languages. If you have more than one, keep pressing until you return to typing in the correct language.
- Check the language on the taskbarIn the lower right corner, next to the clock, look for the icon indicating the active language (for example, ESP or ENG). Click on it and select the correct language. If it's already correct, try changing to another language and then back. This simple reset can resolve conflicts.
- Disable shortcuts if they bother you: If you find yourself accidentally switching languages constantly, go to Settings > Advanced keyboard settings > Input language hotkeys and select “Not assigned.”
These tricks usually resolve most issues related to inadvertent language or layout changes.
Advanced Settings: Control Panel, Layout, and Preferences
If the shortcuts and language icon don't fix the problem, check your system settings thoroughly:
- Access Time and Language settings: From the start menu or by pressing Win + I.
- Select “Language”: In the side menu, you will see the installed languages and distributions.
- Make sure your preferred language is listed first.: You can change the priority to be the first and default.
- Check your keyboard layout: Within the language option, go to "Options" and check the installed keyboards. For Spain, it's usually "Spanish QWERTY." If it's not there, add it and remove the others to avoid conflicts.
- Remove unnecessary languages: Sticking with only the ones you use regularly helps avoid accidental changes.
- Remap keys if all else fails: Programs like power toys o SharpKeys allow you to reassign functions, but only in specific cases.
Correct regional settings ensure that the system and keyboard work in harmony.
Solutions for wireless keyboards and connection problems
For Bluetooth or wireless keyboards, try the following:
- Restart the keyboard and the PC: Disconnect and reconnect the keyboard to reestablish the connection.
- Re-pair the keyboard: In Settings > Devices > Bluetooth, select the keyboard, tap “Remove device,” and then add it again from scratch.
- Change the batteries or make sure it is charged properly.
- Avoid interference: Keep other Bluetooth devices away or USB that may interfere with the signal.
A stable connection is essential for wireless keyboards to work properly.
Physical maintenance: clean and check the keyboard
Sometimes, issues originate in the hardware. If some keys don't respond or several keys are activated at once, consider:
- Deep cleaningUse a keycap puller to remove the keys and clean each one with a damp cloth. Vacuum or blow out any gaps with compressed air, and clean with cotton swabs in difficult areas.
- To portable: Blow compressed air into the gaps and clean with a damp cloth without damaging internal components.
- Dry well if there have been liquids: Let it dry completely and test. If it doesn't work, there may be damage to the internal circuitry and it may need to be repaired.
- Check the placement of the removed keys: Make sure they return to the correct position, especially on models with a Spanish QWERTY layout.
Physical maintenance prevents failures and prolongs the life of the keyboard.
Windows Tools and Software Solutions
If nothing works, Windows has built-in tools:
- Keyboard Troubleshooter: In Settings > Update & security > Troubleshoot > Other troubleshooters, select "Keyboard" and run it. It automatically detects and fixes problems.
- Check the special keys and filters: From Win + U, in Accessibility > Keyboard, disable options that may affect performance.
- Update or reinstall drivers: From Device administratorIn the Keyboards section, right-click and select "Update Driver." If that doesn't work, uninstall it and restart so Windows can reinstall it automatically.
- Set the language correctly: In Settings > Time & language > Language keyboard, remove unnecessary layouts and choose the default.
- Change the key repeat delay: From the Control Panel, adjust the speed to avoid double clicks.
Windows offers several tools to manage and troubleshoot problems without external programs.
Check if the problem is hardware or software
To determine if the fault is with the keyboard or the system:
- Connect another keyboardIf the problem persists, it's likely related to the settings or system. If it works fine, the old keyboard is faulty.
- Try on another computer: Connect your keyboard to another computer. If it still fails, it's probably physically damaged.
- Check the USB ports: Change the ports used to rule out physical connection failures.
These cross-checks make it easier to identify the source of the problem.
Advanced Issues: BIOS and Malware
If the error persists after all the solutions, you can consider:
- Update BIOS and driversAn outdated BIOS can cause errors. Consult the manufacturer's website and follow their instructions for updating.
- Scan for malwareSome infections alter keyboard behavior. Run a deep scan with your antivirus and remove any threats.
These more advanced actions help resolve persistent or complex problems.
