What can I do if the AltGr key in Windows 10 isn’t working?

1. Uninstall/close troublesome programs

We described apps that cause a slew of problems, including tampering with the behavior of keys like AltGr.

After that, simply disabling/uninstalling such programs will most likely solve the problem.

In this regard, ASUS GPU Tweak, remote desktop application, Synaptics driver, and VMWare-like utilities like HyperV have been mentioned.

1.1 Shut down your Remote Desktop Connection

To get the key to work again, you’ll need to close your RDP (remote desktop) session.

Click the Close button on the connections bar to temporarily disconnect from your session (See the horizontal bar near the top of the screen).

1.2 Turn off Hyper-V

  1. Click Apps and Features after pressing the Windows key + X.
  2. Scroll down to Programs and Features, and then click on it.
  3. Select Turn Windows features on/off from the left-hand menu.
  4. Uncheck the Hyper-V option when you find it.
  5. Reboot after clicking OK.

1.3 Remove Synaptics from your computer

  1. Select Device Manager by pressing Windows + X.
  2. Locate the Synaptic device driver and right-click it.
  3. Then choose Uninstall device from the drop-down menu.
  4. To thoroughly remove the driver, uninstall all other instances of the Synaptics device.
  5. It’s possible that you’ll have to go back to the Add/Remove Programs area to uninstall Synaptics.
  6. Check to see if the AltGr key has returned to normal operation after a reboot.

1.4 To repair the mouse, utilize the touch option

Return to Device Manager (as described before) and look for the HID-compliant mouse option under Mouse.

To update the driver, tap it and then press the green icon (with the up arrow). The settings will be updated, and everything should be back to normal.

You should be aware that manual driver updates may not always work, so you may get unexpected results even after completing this step.

2. Type in your language

  1. Select the Settings app from the Start menu.
  2. Then select Time & Language, followed by Region and Language.
  3. Under languages, select Add a language (as above).
  4. Select Next after selecting the keyboard language you want to use from the list.
  5. Examine the available language features and then click Install to add them.
  6. To set the new language as the default, right-click it and choose Set as default (primary).

If you still can’t get AltGr to work, try eliminating all other keyboard layouts except the one corresponding to your language.

By specifying a language choice that works with your keyboard layout and restoring the right configuration of the AltGr key, you may be able to choose a language preference that works with your keyboard layout.

3. Restart the CTFMON.EXE program

  1. Press the WIN+R keys at the same time. The run dialog box appears.
  2. Enter the following command after typing it:
    • C:WindowsSystem32ctfmon.exe
  3. That is all there is to it. Your AltGr key should now function properly.

The Windows process Ctfmon.exe is in charge of alternative user input and the Microsoft Office language bar. So it’s possible that restarting it will fix the problem right away.

4. Keep your system up to date

  1. To begin, press the Start button.
  2. After selecting Settings, go to Update & Security.
  3. Select Windows Update from the drop-down menu. Check for updates by clicking the Check for updates button.
  4. Check if the AltGr key works after rebooting.

5. Make use of alternate keys

Using the combination of Shift + Caps Lock + AltGr can address the problem with the AltGr key in some circumstances.

This is a regular problem with Lenovo and a few other brands of laptops. Furthermore, you may simply replace your AltGr key with CTRL + Alt.
