If I did I don't know how I did it? How can I check?
I was referring to the keyboard software(if any) provided my Microsoft.
Anyway, after having looked up this issue, it looks like only users of wireless keyboards face something like this, probably due to some interference.
So I suggest you trying using this keyboard with another PC and another keyboard with this one, just to isolate the fault with your keyboard.
Cleaning the keyboard may help.
Ultimately, you'll have to get it replaced if the problem persists.
