Initial Fixes

Before we jump to specific solutions for the spacebar not working in Windows, there are a few general fixes you can try. Sometimes you can fix a serious-looking problem just by checking a few connections.

• Make sure your keyboard is clean: dust, food crumbs, and other particles can become stuck behind your keyboard’s keys, making them unable to operate properly. If possible, remove the keys or use cotton swabs to clean between the keys. You can also use compressed air to clear off dust particles obstructing the keys.
• Restart your PC: a system restart refreshes all of your system processes, eliminating any problems caused by system bugs.
• Run the SFC command: SFC is a Windows utility that checks your system for any missing or corrupted files. If it finds any faulty files, it will repair them.
• Roll back the keyboard driver to an earlier version or reinstall the keyboard driver: Driver updates are usually downloaded and installed automatically by Windows. You can also download them manually from the manufacturer’s official website. However, these updates might not be compatible with your system or contain bugs that require later fixes. You can roll back your keyboard drivers from Device Manager or even uninstall them, then restart your PC so that it can reinstall the drivers automatically after the boot sequence.

1. Connect the Keyboard to a Different USB Port

Most keywords connect to a PC via a USB port unless they are wireless. Even the wireless ones can sometimes connect to your PC via a USB dongle.

Either way, checking your PC USB ports for any dust that could interfere with the keyword connection would be helpful. Then try connecting the keyboard to a different USB port and see if the Spacebar is now operational.

2. Run the Windows Keyboard Troubleshooter

Windows has various troubleshooters that can help you diagnose your problems and effectively solve them. Conveniently enough, there is a dedicated Keyboard troubleshooter you can run.

1. Right-click the Start menu and select “Settings.”

2. Go to “System -> Troubleshoot.”

3. Click on “Other troubleshooters.”

4. Click the “Run” button next to the Keyboard troubleshooter.

5. If the troubleshooter finds problems with your keyboard, it will instruct you on how to fix it. If no problems are found, you will see the message “No changes or updates were necessary.”

3. Disable Sticky Keys and Filter Keys

The Sticky Keys feature is an accessibility feature that allows users to activate multiple keys together while pressing them one at a time. If you’ve enabled this option, Windows will assume that you’re trying to press a shortcut sequence and won’t register your Spacebar strokes.

Another feature that may cause your Spacebar not to function is Filter Keys, which, if activated, can ignore repeated keystrokes. To avoid any issues, you should make sure that both options are disabled by following the steps below:

1. Right-click the Start menu and select “Settings.”
2. Go to “Accessibility -> Keyboard.” In Windows 10, you’ll need to head to “Settings -> Ease of Access -> Keyboard.”

3. The first two options are “Sticky keys” and “Filter keys.” Turn both off.

4. Enable Human Interface Device Service

Simply put, the HID, or Human Interface Device, is responsible for receiving input data from keyboards, gamepads, and mice when connected to a USB port. If this service is disabled, then your Windows PC won’t be able to recognize any input from your keyboard.

1. Press the Win + R keys simultaneously to launch the Run app.
2. Type services.msc in the box and press Enter.

3. In the list of services, look for “Human Interface Device Service.” Once found, click on it, and select “Start” in the “Service status” section.

4. If the “Startup type” is “Disabled,” set it to “Manual” and click “Apply.”

5. Uninstall the Most Recent Windows Update

While it’s rare to see a Windows update cause keyboard problems, such as the spacebar not working, it can happen. If you suspect that is the issue, uninstall the most recent Windows update.

1. Right-click the Start menu and select “Settings.”
2. In the “Windows Update” tab, click “Update history.”

3. Scroll down to the end of the updates list and click on “Uninstall updates.”

4. You will find all of your installed updates and dates of installation here. Identify the most recent update, click on it, and select “Uninstall.”

As an alternative, you can restore your system to a previous restore point. If you have created a restore point via System Restore, you can use it to bring your PC back to an earlier state when the Spacebar was still working.

6. Reset BIOS to Default

Suppose your BIOS is corrupted, or you recently made some adjustments to it, then your PC won’t be able to boot correctly, resulting in hardware problems. To undo any changes to the BIOS, you should reset it.

1. Turn your computer on and rapidly press the BIOS key as soon as the Windows logo appears. Depending on your PC manufacturer, this key can vary, but the most common ones are Esc, Delete, F1, F2, F10, F11, or F12.
2. Navigate with the arrow keys to the “Exit” tab.
3. Find “Load Setup Defaults” and press Enter.

4. You may need to confirm your choice again.

5. Your PC will restart, and the BIOS will return to its factory settings. Not that you will not lose any data in the process.
