There can be many reasons why the Mouse double-click does not open files & folders in Windows. Here are some fixes to resolve this issue.

It could be due to wear and tear, or it could be due to something else. Before you buy a new mouse straight away, here's what you can try to fix it.

Whenever I've had problems with Logitech mouse double-clicking when a single click was intended, it was a hardware issue with the contacts on the buttons.

All double-click problems I ever had with any Logitech mouse, including my current MX performance ceased when I stopped using the Logitech mouse drivers.

Usually, a virus infection, improperly configured mouse double-click speed, File Explorer settings, etc., are the causes of this issue. It is also a system file that is password-protected.
