Touch keyboard is not being displayed on Windows 10 IoT Enterprise 2019 LTSC (64 Bit)

Question

We have the issue that the touch keyboard is not displayed on Windows 10 IoT Enterprise 2019 LTSC (64 Bit).

We have attempted the following modification but we have not soleve the issue.

After the OS starts, when the input field on the application screen is focused, only the touch keyboard area appears, but the keyboard itself does not show up.

Then, we forcibly terminated the keyboard process (InputApp.exe) before focusing on the input field.

However, even with the previous modify, the touch keyboard did not appear after focusing on the input field.

As a further modify, we added a process to monitor the launch of the keyboard process (InputApp.exe) and forcibly start it from the program.

Despite these efforts, the issue remains unresolved in some cases. Specifically, only the keyboard area appears, and the keyboard itself does not.

This problem does not occur on IoT Enterprise 2016 LTSB or Windows 11 IoT Enterprise, however the software is different.

We need any information or OS KB information to fix or avoid this issue if you have.

As of now, the latest update for Windows 10 IoT Enterprise 2019 LTSC is KB5029244 (August 2023). If you haven’t applied this update, it might help.

Go to Settings > Devices > Typing.

Scroll down to Touch keyboard and make sure Show the touch keyboard when not in tablet mode and there's no keyboard attached is enabled.

Open PowerShell as Admin and copy-paste the following:

Get-AppxPackage Microsoft.Windows.InputExperience | foreach { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" }

Hi Takashashi,

Thanks for your post. It sounds like there is some incompatibility with keyboard and Win10 IoT Enterprise 2019 LTSC. Kindly try the following methods to repair the system at first.

1. Install the latest update for Win10 IoT Enterprise 2019 LTSC
2. Run the SFC and DISM Scans

Corrupted or missing system files may lead to the incompatibility issue. In this case, you can try to fix it by running the SFC and DISM scans. To do this, follow the steps below.

Step 1: Press Windows + R to open the Run dialog.

Step 2: Type cmd in the text box and press Ctrl + Shift + Enter to run Command Prompt as an administrator.

Step 3: Type these commands. sfc /scannow (and press Enter) Dism /Online /Cleanup-Image /ScanHealth (and press Enter) Dism /Online /Cleanup-Image /CheckHealth (and press Enter)

The DISM tool will report whether the image is healthy, repairable, or non-repairable. If the image is repairable, you can use the /RestoreHealth (Dism /Online /Cleanup-Image /RestoreHealth) argument to repair the image.
