How to Disable Windows Ink Pen Detection in Adobe Acrobat
Question details
The user wants to stop Adobe Acrobat from automatically using the Surface Pen for markup, preferring it to act as a standard mouse or stylus pointer.

- Product
- Adobe Acrobat
- Device & OS
- Microsoft Surface / Windows
- Scenario
- Using a Surface Pen or stylus to navigate PDF documents without accidentally drawing or highlighting on the screen.
- Observed behavior
- Acrobat automatically detects the pen as a markup input tool instead of a navigational pointer.
Ensure your Adobe Acrobat application is updated to the latest version, as the exact location of the commenting and pen settings may vary slightly in much older releases.
Disable 'Auto Detect Pen Hardware' in Preferences
By modifying the Commenting preferences, you can prevent Acrobat from automatically switching to markup mode when the pen touches the screen.
Adobe Acrobat natively integrates with Windows Ink to make annotating seamless. However, this overrides standard navigation gestures. Disabling this specific hardware detection forces Acrobat to treat your pen like a regular mouse pointer.
Launch Adobe Acrobat. Navigate to 'Edit' in the top menu bar and select 'Preferences' from the dropdown list. Alternatively, you can use the keyboard shortcut Ctrl+K.
In the Preferences window, look at the left-hand Categories pane and click on 'Commenting'.
Scroll down through the Commenting options until you find the setting labeled 'Auto Detect pen hardware to enable markup'. Clear the checkbox next to this option.
Click the 'OK' button at the bottom of the Preferences window to save your settings. You may need to restart Acrobat for the changes to take full effect.

Try WPS Office for a Seamless PDF Reading and Editing Experience
If you are frustrated with rigid settings in other PDF readers, try WPS Office. It includes a powerful, lightweight PDF editor that seamlessly handles touch devices and stylus inputs, giving you complete control over when to navigate and when to annotate.
- 1. Download and Install: Download WPS Office for free from the official website and follow the installation prompts.
- 2. Open Your PDF: Launch WPS Office, click on 'Open', and select your PDF file to view it in the built-in PDF editor.
- 3. Navigate or Annotate Flexibly: Use your Surface Pen naturally to scroll and select text, or switch to the 'Comment' tab to activate dedicated markup tools.

Frequently Asked Questions
Can I still draw on my PDF after disabling automatic pen detection in Acrobat?
Yes. Even with automatic detection disabled, you can manually select the drawing, highlighting, or comment tools from the Acrobat toolbar to mark up your document whenever you need.
Why does my Surface Pen default to drawing in PDF documents?
Many modern PDF applications, including Adobe Acrobat, are optimized for Windows Ink. They assume that when a pen touches the screen, the user intends to draw or annotate rather than scroll or select text.
Will disabling this setting affect my mouse or trackpad?
No, this setting only changes how Acrobat interprets input from pen hardware like the Surface Pen. Your mouse and trackpad will continue to function normally for navigation and text selection.
Where are the Commenting preferences located in Adobe Acrobat for Mac?
On a Mac, you can access the Commenting preferences by clicking 'Acrobat' or 'Acrobat Reader' in the top-left menu bar, then selecting 'Preferences' (or pressing Cmd+,), and choosing 'Commenting' from the left pane.
