A broken Tab key instantly disrupts your workflow – whether you’re using Alt + Tab, jumping between form fields, or indenting text. If your Tab key is not working on Windows 11 or 10, you’re not alone. This issue is usually caused by an accidental accessibility setting, a background app blocking the key, or a faulty keyboard driver, and it’s usually not difficult to fix.

How to fix Tab key not working on Windows

We’ve put together the most reliable, proven solutions for the Tab key not working on a Windows PC, arranged from the quickest checks to deeper driver fixes. Work through the list in order until your Tab key starts working again.

Preliminary check: Test the on-screen keyboard

Before diving into system settings, run a quick test to confirm whether the problem is physical or software-based:

  1. On your keyboard, press the Windows logo key + R to open the Run dialog. Type osk and press Enter to launch the On-Screen Keyboard.
    open on-screen keyboard via run command
  2. Open a browser window or Notepad, then click the virtual Tab key with your mouse.

If the on-screen Tab key works: Windows can process the Tab command normally. The issue points to physical debris under your keycap, a failing switch, or a driver hook misinterpreting the physical keystroke. Try Fix 1 and Fix 5 first.

If the on-screen Tab key also fails: The problem is related to the Windows settings, an active keyboard hook, or an accessibility feature blocking the input system-wide. You can head straight to Fix 2, Fix 3, and Fix 4.

  1. Restart your computer and check the physical connection
  2. Turn off Filter Keys
  3. Close TeamViewer and unnecessary background apps
  4. Clear stuck modifier keys
  5. Update the keyboard driver

Fix 1: Restart your computer and check the physical connection

A simple restart can fix temporary system glitches and refresh your hardware connection. It is the quickest and easiest way to get your keyboard working again.

  1. Save your work and restart your computer.
  2. If you are using a wired external keyboard, unplug the cable, wait 10 seconds, and reconnect it directly to a USB port (avoid unpowered USB hubs).
  3. If you are using a wireless keyboard, inspect the battery level, re-pair the Bluetooth connection, or move the 2.4 GHz USB dongle to an unobstructed port.
  4. Clean around and beneath the Tab keycap using a can of compressed air to dislodge any accumulated dust, crumbs, or moisture.

Once Windows reloads, open Notepad and tap Tab to verify if indentation works.


Fix 2: Turn off Filter Keys

Filter Keys is a Windows feature that ignores brief or repeated keystrokes. You might have accidentally turned it on by holding down the right Shift key for 8 seconds. You can try turning it off to see if that brings your Tab key back to life.

Windows 11

  1. Right-click the Start button and select Settings.
    open windows settings
  2. Go to Accessibility > Keyboard.Windows 11 - disable filter keys via Settings
  3. Toggle off Filter keys.
  4. Now try using your keyboard and see if how it works.

Windows 10

  1. Click the Start menu (the Windows logo) at the bottom left of your screen. Then click Settings.
  2. Click Ease of Access.
    ease of access on windows 10
  3. Click Keyboard.
    ease of access keyboard setting windows 10
  4. Disable the Filter Keys function (switch off Filter Keys or uncheck Turn on Filter Keys).
    disable filter keys on windows 10
  5. Try your keyboard and see if disabling Filter Keys can restore your keyboard.

Fix 3: Close TeamViewer and unnecessary background apps

Background apps—especially remote desktop tools like TeamViewer or gaming macro software—can sometimes “hijack” your Tab key for their own shortcuts. Closing these apps completely will likely release the key and return it to normal.

  1. On your keyboard, press Ctrl + Shift + Esc simultaneously to open Task Manager.
  2. Under the Processes tab, look for TeamViewer, AnyDesk, or similar remote-access utilities running in the background.
  3. Right-click the application and select End task.
    end app and process in task manager
  4. Check your system tray (bottom-right corner of the taskbar), right-click any background overlay or macro tool, and exit the program.

Switch back to your browser or word processor and press Tab to see if standard navigation returns.

Fix 4: Clear stuck modifier keys

Sometimes, modifier keys like Alt, Ctrl, or the Windows key get confused and act like they are permanently pressed down. When this happens, hitting Tab triggers a shortcut (like Alt + Tab) instead of a normal space. Here’s how to reset these key combinations and unstick them.

  1. Tap the left Alt key twice, then tap the right Alt key twice.
  2. Tap the Ctrl key twice. Then tap the Windows logo key twice.
  3. Open a text editor (like Notepad), press and hold the Alt key, type 009 on your numeric keypad, and release the Alt key.

This sends the direct ASCII tab character code. If a tab space appears, your operating system is accepting tab characters, confirming that the issue lies with the physical switch or key mapping rather than text handling.

Fix 5: Update the keyboard driver

If your keyboard driver is corrupted or outdated, Windows won’t be able to understand your keystrokes properly. You can simply update or reinstall the driver to give your keyboard a fresh start and fix communication errors.

There are two ways to update your keyboard driver:

1. Manually update the keyboard driver – You can go to the manufacturer’s website for your keyboard or your PC, find the latest correct driver for your keyboard device, and install it on your computer. Be sure to download the driver that is compatible with your OS. You can read the detailed manual instructions in our article: Download & Install Keyboard Driver for Windows 11/10/8/7 Step by Step.
