I have a Microsoft wireless keyboard 1000 and it just started imputing different characters instead of the ones i wanted. Such as 4 instead of s and ; instead of a another examples is space types in x. I didn't spill anything on the keyboard it was working earlier today. I am typing on another keyboard attached to the same computer at the same time and it has no issues. I am running on Windows 8 if that matters. Any help would be greatly appreciated.
