Why Does My Mouse Highlight Everything When I Click? Common Causes Explained
If your mouse is selecting or highlighting everything on the screen when you click, you’re not alone—this is a surprisingly common issue among Windows users. Understanding the root cause is the first step toward resolving the problem effectively. Several factors can trigger this mouse behavior, ranging from hardware faults to software glitches.
- Malfunctioning Mouse Button: A worn-out or defective mouse button can cause it to register multiple clicks unintentionally, leading to your system selecting everything under the cursor with a single click. This is especially common in older or heavily used mice.
- Dirty or Damaged Sensor: Dust, debris, or physical damage to the mouse sensor can interfere with its ability to accurately track movement, resulting in erratic behavior like mass highlighting or jittery cursor motion.
- Software or Driver Issues: Outdated or corrupt mouse drivers, incorrect system settings, or third-party software conflicts can cause abnormal input responses. These issues may cause the operating system to misinterpret a single click as multiple commands.
To determine if the issue is hardware or software related, try connecting your mouse to another computer. If the problem persists, it’s likely the mouse itself. If the mouse works fine elsewhere, your current system’s settings or drivers may be to blame.
In the next section, we’ll guide you through step-by-step troubleshooting methods to help you fix this issue and restore your mouse’s normal behavior.

Running regular SFC scans can help maintain system health and prevent unexpected glitches, ensuring a smoother Windows experience overall.
Method 9: Run DISM to fix Windows System Image
If your mouse continues to highlight everything upon clicking, and traditional troubleshooting hasn’t worked, it’s time to use the Deployment Image Servicing and Management (DISM) tool. DISM is a powerful command-line utility in Windows designed to fix deeper system-level issues, including those caused by corrupted Windows images or misconfigured system files.

Here’s how to run the DISM tool on Windows:
- Click on the Search bar in your taskbar or press
Windows + S, and type Command Prompt. - From the search results, right-click on Command Prompt and choose : Run as administrator.
