Detailed Fixes for “Enter key doesn’t work in Windows 10”
1. Physical key failure (hardware)
Why this causes the problem:
Mechanical or membrane switches under the Enter key can fail with age, excessive use, or impact. A failed switch simply won’t register the keypress.
Step-by-step solution:
- Test with the On-Screen Keyboard: Press Start → type osk → press Enter (or click) and click the Enter key on the on-screen keyboard. If it works, Windows responds and the problem is likely hardware.
- Test with an external keyboard: Plug in a USB keyboard or connect a Bluetooth keyboard. If the external keyboard Enter works, the laptop/primary keyboard hardware is at fault.
- Test in BIOS/UEFI to confirm hardware independence: Restart PC and enter BIOS/UEFI (common keys: F2, Esc, Del) and try the Enter key in any selectable field. If Enter doesn’t work in BIOS either, it’s almost certainly hardware.
- Repair/replace: For external keyboards, replace cheaply. For laptop internal keyboards, consider professional repair or replacement; if comfortable, consult manufacturer guides to replace the keyboard or check/replace the ribbon cable.
Notes:
- For mechanical keyboards you can replace a single switch if you know soldering or buy a replacement board.
- If the key works intermittently, it might be a loose ribbon cable or worn switch.
2. Dirt, debris, or liquid damage
Why this causes the problem:
Dust, crumbs, hair, or residue from spills can block the physical contact or jam the keycap, and corrosion from liquids can break the electrical contact.
Step-by-step solution:
- Power off the device and disconnect power/USB.
- Use compressed air to blow around the Enter key at an angle (short bursts) to dislodge debris.
- For removable keycaps (desktop/mechanical), gently pry off the Enter keycap using a keycap puller and clean with isopropyl alcohol and a soft brush; allow to dry fully before reassembling.
- For laptop keys, follow manufacturer instructions for keycap removal (if supported) or use compressed air and isopropyl cleaning around the edges.
- For liquid spills: power off, remove battery if possible, and seek professional cleaning; do not power on if wet.
Tips:
- Avoid excessive force; key mechanisms are delicate.
- Small crumbs often block only one key — cleaning usually resolves it.
3. Incorrect keyboard layout, input language, or Fn/NumLock state
Why this causes the problem:
If Windows is set to a different keyboard layout or language, the physical Enter key may behave differently or another key might be mapped. Some laptops have Fn lock keys that change key behavior (e.g., Enter shifted to a secondary function). On embedded numeric pads, Num Lock can alter behavior.
Step-by-step solution:
- Check active layout: Go to Settings > Time & Language > Language and ensure your preferred language is set as default.
- Advanced keyboard settings: Open Settings > Time & Language > Region & language (or Language), then click Advanced keyboard settings and verify Override for default input method is correct.
- Use the language bar on the taskbar (or press Windows + Space) to cycle layouts and test Enter.
- Check Fn/Lock/NumLock: Look for an Fn Lock key or Num Lock status; press Fn + Esc or the dedicated FnLock key to toggle, and test again.
- Remove extra layouts: In Settings > Time & Language > Language, remove extra keyboard layouts you don’t use.
Notes:
- Some apps (remote desktop, VMs) can set their own layout — test Enter in Notepad to isolate global vs app-specific behavior.
4. Accessibility settings (Filter Keys, Sticky Keys, Toggle Keys)
Why this causes the problem:
Accessibility features like Filter Keys can ignore brief key presses or reduce repeats, making Enter appear unresponsive.
Step-by-step solution:
- Open Settings > Ease of Access > Keyboard.
- Turn off Sticky Keys, Toggle Keys, and Filter Keys (make sure Use Filter Keys is set to Off).
- If Filter Keys was on, restart or test immediately by pressing Enter in Notepad.
- If settings keep re-enabling, check that no third-party accessibility tool is forcing them on.
Tips:
- Filter Keys can be toggled accidentally by holding Shift for eight seconds — uncheck the shortcut under the Filter Keys settings.
5. Corrupt or outdated keyboard driver
Why this causes the problem:
Drivers connect hardware to Windows. A corrupt, outdated, or wrong driver can prevent key events from being recognized.
Step-by-step solution:
- Open Device Manager: Right-click Start → Device Manager.
- Expand Keyboards and right-click your keyboard device (e.g., HID Keyboard Device).
- Select Update driver → Search automatically for updated driver software.
- If that doesn’t help: right-click → Uninstall device. Check Delete the driver software for this device only if you have another driver, otherwise simply uninstall and restart Windows (it will reinstall the driver automatically).
- If uninstall/reinstall doesn’t work: on the top menu, click Action > Scan for hardware changes.
- If using a manufacturer keyboard (e.g., Logitech, Corsair), download the latest driver or firmware from the manufacturer site and install it.
Notes:
- For wireless keyboards, ensure Bluetooth drivers are updated under Bluetooth in Device Manager.
6. Third-party software or malware intercepting Enter
Why this causes the problem:
Some applications (hotkey managers, game overlays, macro tools) or malware can capture or remap Enter key events.
Step-by-step solution:
- Try a clean boot: Press Windows + R, type msconfig, press Enter. In the Services tab, check Hide all Microsoft services, then click Disable all. In Startup, open Task Manager and disable all startup items. Restart and test Enter.
- If Enter works in clean boot, re-enable services/startup items one-by-one to find the culprit.
- Run a malware scan: Open Windows Security → Virus & threat protection → Quick scan. For thoroughness, run a full scan and use a second opinion tool like Malwarebytes.
- Check running apps: Close any keyboard-hooking apps like AutoHotkey, clipboard managers, or gaming overlays and test.
Notes:
- If you find the culprit, either update the app, reconfigure its hotkeys, or uninstall it.
7. System file corruption or Windows Update bug
Why this causes the problem:
Corrupt system files, bad Windows updates, or registry issues can break keyboard handling in the OS.
Step-by-step solution:
- Run System File Checker: Open Command Prompt (Admin) — press Start, type cmd, right-click Command Prompt, select Run as administrator. Type sfc /scannow (bolded command) and press Enter. Wait for completion and follow any prompts.
- Run DISM if SFC reports issues: In the same elevated prompt, run DISM /Online /Cleanup-Image /RestoreHealth.
- After these scans, restart and test the Enter key.
- If problem began after a recent update: go to Settings > Update & Security > Windows Update > View update history > Uninstall updates, select the recent update and uninstall.
- Consider System Restore: Press Start → type rstrui → Enter, then choose a restore point from before the issue started.
- As a last resort, consider Reset this PC (Settings > Update & Security > Recovery > Reset this PC) with the option to keep files.
Notes:
- Always back up important data before major repairs or resets.

FAQ
Can I remap the Enter key to another key temporarily?
Yes — use Microsoft PowerToys > Keyboard Manager to remap a different key to act as Enter. This is useful while waiting for hardware repair.
Why does Enter work sometimes but not always?
Intermittent behavior usually indicates hardware (loose connection, worn switch), low battery on wireless keyboards, or an app occasionally capturing the key. Run the hardware tests and a clean boot.
How do I test if the keyboard hardware is dying?
Test with the On-Screen Keyboard, an external keyboard, and in BIOS/UEFI. If Enter fails in BIOS, the hardware is failing; if BIOS works but Windows doesn’t, check drivers and system files.
Can a Windows update break the Enter key?
Yes — updates can introduce driver conflicts or bugs. If the issue started after an update, uninstall the update via Settings > Update & Security > Windows Update > View update history > Uninstall updates or use System Restore.
Is it safe to remove a laptop keycap to clean it?
Only remove laptop keycaps if your manufacturer documents how to do it — many laptop keys are fragile. For desktop mechanical keys, keycap removal is usually safe with a puller.
