A mouse has two buttons for clicking and the click executed from each button has a different function. The right-click button can only click once but the left-click button can click once to select an item, and it can be used to click twice to execute a function, normally to open or execute something.
The double-click is a deliberate action i.e. the user will execute it when they want to open a file, select an item, open a sub-menu, run a script etc. At no point does Windows 10 decide on behalf of the user that double-click should be executed.
Experiencing mouse double clicks
If your mouse is executing a double-click when it shouldn’t there may be several reasons behind this. Normally, this points to a problem with the mouse settings or a particular app that’s running on your system. We should still rule out hardware problems before we proceed to a fix. You can do that by performing a basic hardware check.
Why is my mouse double clicking?
Basic hardware check
In order to run a basic hardware check you must have an extra mouse available on hand. A mouse is a cheap peripheral to purchase and you can use any type i.e., wired or wireless.
- Connect a different mouse to your system and check if the double-clicks are still executed.
- Connect the mouse to a different port and check if the double-clicks are still executed.
- If your PC has a trackpad, check if the double-clicks are executed from it as well.
If double-clicks are still executed in all of the above cases, you have a software problem on your hands. Try the fixes below.
1. Check double-click speed
Windows 10 allows users to set when a double-click is executed i.e., how long the OS should wait between consecutive left-clicks to register it as a double-click. If this interval is set too low or too high, you will often execute a double-click when you do not intend to.
- Open the Settings app with the Win+I keyboard shortcut.
- Go to Devices.
- Select the Mouse tab.
- Click Additional mouse options.
- In the window that opens, go to the Buttons tab.
- Use the slider at the bottom to reduce or increase the double-click speed and test it out.
- Disable ClickLock on the same window.
2. Uninstall and reinstall mouse driver
The mouse driver may have run into problems. This tends to happen after a major Windows 10 update but smaller, routine updates can also cause problems. The fix is to uninstall and reinstall the mouse driver.
- Open Device Manager.
- Expand Mice and other pointing devices.
- Right-click the mouse and select Uninstall device from the context menu.
- Allow the device to uninstall.
- Disconnect the mouse from the system.
- Connect the mouse again and drivers for it will be installed automatically.
3. Remove third-party apps
If you have third-party apps installed for managing or modifying the behavior of the mouse, disable or uninstall them. This includes scripts that you may be running to change how a mouse clicks, scripts or apps that remap the mouse buttons for a particular app e.g. a game, or proprietary mouse apps like those from Logitech.
4. Check for app-specific behavior
Check if the behavior is app-specific e.g., the mouse double-clicks but only does so in a particular app, it is a problem with the app and not the mouse. Check the preferences for the app and if you can change how the mouse works. Again, this tends to happen more often in games but games normally have extensive settings for a mouse. Go through them and change how the mouse behaves.
Mouse keeps double clicking?
The mouse isn’t a complicated peripheral and while Windows 10 has extensive settings available to customize how it works, they are simple enough to understand and configure.
You’re highly unlikely to enable anything that would change basic behavior like double-clicking.
