Strange mouse clics behavior

On my Dell portable (Vostro, Windows 10) very often, when I clic some item, the concerned program (for example Outlook) behaves as if I did a double-clic
At other places the same, as if I right click (when in fact I left clic)
Help !

Is this a touch pad or an actual mouse? Are you clicking with a button, or by tapping a touch pad?

And you can always run the Dell tools to see if there is a problem: https://www.dell.com/support/article/in/en/inbsd1/sln114988/dell-diagnostic-tools-to-diagnose-and-fix-hardware-problems-on-your-dell-pc-tablet-or-servers?lang=en

My laptop behaves similarly, several keys are partially jammed down from misuse. Don't know whether to buy a new keyboard to match the laptox or jist pug a UsB one innn instd. Seriously though does it do the same if you disable the inbuilt keyboard and use a USB one?
Owen RubinConsultantCommented:
I agree with Andy here, as a broken keyboard can cause these issues for sure.

For example, if the Control key is stuck on, left mount clicks become a right click. (Ctrl-Left click = right click)
A bad button on the mouse can cause "bounce" which makes the click look like many clicks.

If you have an external keyboard, plug that in and disable the internal keyboard to see if the problems go away. That would indicate a bad keyboard.

If that does not work, try disabling the internal mouse and try an external mouse to see if that corrects the problem.

Speed mouse slower, ok, where can I change this ?
Thanks
nobusCommented:
in device manager, or the software for your mouse
Changing Your Mouse Speed.
 To change the speed of your mouse or trackpad cursor in Windows 10, first launch the Settings app from the Start Menu and select Devices.
On the Devices screen, select Mouse from the list of sections on the left, and then select Additional Mouse Options on the right side of the screen
