1] Restarting Windows File Explorer
This is probably the easiest thing to do – and sometimes it helps. To restart Windows Explorer, you must open the Task Manager. Press Ctrl + Shift + Esc to open the Windows Task Manager. Then use the down arrow key to select Windows Explorer and press the tab key to select Restart . Then click on it with the Enter key (16).
Change USB port and check. Sometimes it can help for no reason.
3] Reinstall the mouse driver
An obsolete or damaged device driver can cause such problems. You must update or reinstall the mouse driver. To do this, open the Device Manager from the Win X menu. Locate the mice and other pointing devices, then right-click to open its properties. Go to the tab Driver > and click the button Uninstall device .
Then follow the option on the screen to uninstall it completely.
Disconnect and reconnect the mouse to reinstall the mouse driver.
If you have your own driver on your computer, you can also install it – or you can search for it on the manufacturer’s website.
4] Check mouse properties
Open settings > Devices > Mouse > Additional mouse opens. The mouse properties are open. Click the Buttons tab. Activate the Click Lock option and click Apply. Then deselect this option and click Apply again. Let’s see if it helped.
5] Creating a new user account
Sometimes a corrupted user account can cause such problems on your computer. Therefore, the simple solution is to create a new user account.
6] Run the DISM tool
The DISM tool is another command line tool available on a Windows computer. You can repair various corrupted system files using this simple and free tool. To run DISM, open the command prompt with administrative rights and enter this command :
DISM /Online /Cleanup image /RestoreHealth
It takes a few minutes to check everything and try to solve the problem automatically. Do not close the window if it takes time.
7] Check in the clean start state
Start a clean start and see if the left mouse button works. If so, you will need to manually identify the offensive process and see if you can uninstall it.
8] Uninstall the newly installed software
If you have recently installed software or drivers such as video drivers, audio drivers, etc., try uninstalling them. In many cases, it has turned out that the driver or software recently installed is the cause of the problem. After restarting, check whether it works or not.
