Hi Darkcyde4122,
I am Dave, I will help you with this.
1
Open Device Manager, then expand the 'Mice and other Pointing devices' section, right click and uninstall the mouse driver.
Then unplug your mouse, and reconnect it, Windows should then load a new driver for the mouse.
2
If that does not solve the problem, open the old Control Panel, not the Settings App, and in the old Control Panel, set View to icons.
Open the Mouse applet, on the resulting utility, set the double click speed slower than currently set, save that setting and restart (not shit down) your PC and check if the problem still exists.
