I have an Acer Aspire E1-771 laptop running on 8.1. A couple of years old. It has been doing the below for a year-or-so, but I usually use a remote keyboard at home. Now more transient at work so I need the keyboard to work properly.
With a USB-connected remote keyboard all works well.
Disconnecting and using only the laptop keyboard I get all sorts odd spurious actions, eg: most actions using the ctrl and another key (ie cut, or paste, undo, etc) results in Word/Internet double spacing of the paragraph, the addition of '12'...' into the text and the 'open file' in Explorer then opening!! Or various other weird combinations.
Think I need to reload keyboard driver. How? Please
