Adjusting the Mouse Sensitivity

You can select multiple files in Explorer by clicking the first one, then holding down the Ctrl key while clicking additional files. But some people see copies of all the selected files suddenly appear when they do that. Now Sometimes the mouse is to sensitive that why files usually just pop up

Run regedit and navigate to the key

HKEY_CURRENT_USER\Control Panel\Desktop

look for the values DragHeight and DragWidth; if it’s not there, create them as REG_SZ type. The default values are 4 pixels; to reduce the sensitivity of your mouse make the values larger, such as 25.
