Hi. I installed AVG pc clean up and not sure if it was this that caused the problem. I downloaded the microsoft doc to find the prob and it seems my keyboard filter and driver device LEXMARK X422 is missing.
Should I contact my pc manufacturer or microsoft for this prob please I have a HP lap top windows 7.
I am not to clever with all the jargon on a pc so not sure what to do I dont want to mess around with it. Thanks.
