Hello. I often need to click an element multiple times in order to activate it. I have not experienced the issue with the right-click. My mouse does not seem to be the issue so what could be the problem?

Hundreds of users have flooded the Microsoft community forum complaining about the left mouse click not responding on Windows 10 and 11 devices. For some reason, users have to click on buttons multiple times before Windows reacts. Microsoft has not responded to complaints and has not addressed the issue so far, so it is unknown what could have caused it and how users could fix it.

We prepared a step-by-step guide consisting of 6 steps that seem to have helped some people deal with the left click not working in Windows. Some users guess that the big could have been caused by corrupted system files, third-party antivirus software, changes in the settings, or outdated mouse drivers. The first thing you should do before proceeding with the troubleshooting is to check if the mouse you are using works fine connected to another device to rule it out as the cause.

If you have done that, and the left click works without issues on another PC, there might be an issue with your Windows machine. The manual troubleshooting process could take a while, so you can use a repair tool like [d1] that can fix various system errors, corrupted files, registry[ref en-1] issues, etc. This powerful software can also automatically clear cookies[ref en-2] and cache,[ref en-3] which many users forget to do regularly.

Otherwise, if you are ready to begin the guide, follow the steps below carefully and in an orderly manner. We also previously wrote a guide on how to fix mouse right-click so if none of the steps in this article will help, you can look for additional ideas there.
