These symptoms can affect various Windows 11 devices including Surface tablets, 2-in-1 laptops, and traditional touchscreen computers.

Step-by-Step Guide to Re-enable TabletInputService

Method 1: Using Services Manager

The most straightforward approach to restoring touch functionality involves using Windows Services Manager. Press Windows Key + R, type "services.msc," and press Enter to launch the Services application. Scroll through the list of services and locate "Touch Keyboard and Handwriting Panel Service." Right-click on this service and select "Properties" from the context menu.

In the Properties window, ensure the "Startup type" is set to "Automatic" to guarantee the service starts with Windows. If the service status shows "Stopped," click the "Start" button to initiate it immediately. After starting the service, click "Apply" and then "OK" to save your changes. Test your touchscreen and pen functionality to verify the fix has resolved the issue.

Method 2: Using Command Prompt

For users comfortable with command-line tools, Windows Command Prompt offers an efficient alternative. Open Command Prompt as Administrator by right-clicking the Start button and selecting "Windows Terminal (Admin)" or "Command Prompt (Admin)." Type the following command and press Enter: sc config TabletInputService start= auto

This command configures the service to start automatically. Next, start the service immediately by entering: sc start TabletInputService

The system should confirm that the service started successfully. This method is particularly useful when the Services application is inaccessible due to touch input issues, as it can be executed entirely via keyboard.

Method 3: Using Windows PowerShell

Windows PowerShell provides another powerful option for service management. Launch PowerShell as Administrator and run: Set-Service -Name "TabletInputService" -StartupType Automatic

Follow this with: Start-Service -Name "TabletInputService"

PowerShell offers more detailed feedback and additional parameters for advanced users who need to troubleshoot more complex service issues.
