Let’s see these solutions in detail.

1] Run Hardware and Devices Troubleshooter

Because the issue that you are experiencing might be related to hardware, running the Hardware and Devices Troubleshooter can help fix it. It is an automated tool that tries to find the cause of the problem and fixes it (if possible).

2] Scan your computer with Microsoft Safety Scanner

One possible cause of the problem is virus or malware infection. Microsoft Safety Scanner is a free tool developed by Microsoft that scans your system for infection and removes all the malicious programs that it finds. This tool is available on Microsoft’s official website.

3] Update your mouse driver

The outdated and corrupted device drivers also cause several issues on a system. We suggest you update your mouse driver and see if it helps. To update your mouse driver, follow the steps listed below:

1. Right-click on the Start Menu and select Device Manager.
2. In the Device Manager, expand the Mice and other pointing devices node.
3. Right-click on your mouse driver and select Update device.
4. Now, select the Search automatically for drivers option.

After that, Windows will search for the latest version of your mouse driver and install it on your system. After updating your mouse driver, check if the issue persists.

4] Uninstall and reinstall your mouse driver

If updating the mouse driver does not work, try to reinstall it. We have listed the steps for the same below:

After uninstalling the mouse driver, restart your computer. After restarting the device, Windows will detect the hardware changes and reinstall the missing driver.

5] Check if ClickLock is turned on

ClickLock is a feature in Windows 11/10 that lets users highlight or drag without holding the left mouse button. This feature is useful for laptop users. Open the Control Panel and check if you have enabled this feature accidentally.

Follow the steps below:

1. Press Win + R keys to launch the Run command box.
2. Type Control Panel and click OK.
3. In the Control Panel, select Large icons in the View by mode.
4. Click Mouse.
5. Select the Buttons tab and deselect the ClickLock option (if it is selected).
6. Click Apply and then OK.

6] Turn off the Sticky Keys

Disabling the Sticky Keys has fixed the issue for many users. You can also try this. Turn off the Sticky Keys and see if it brings any changes.

7] Run SFC and DISM scans

SFC or System File Checker is an automated tool from Microsoft that helps users fix missing and repair corrupted system files. If the issue is occurring due to missing or corrupted system files, running an SFC scan will fix it.

DISM or Deployment Imaging and Servicing Management tool is used when the SFC tool fails to repair the corrupted system files. If the SFC scan does not fix your problem, you can run the DISM scan.

8] Restore the previous version of Windows

If you are experiencing the issue after installing a recent Windows update, restoring back the previous version may fix it.
