Since running a recommended registry cleaner program I have experienced numerous problems. It has been suggested I restore the registry to the factory backup in the SAMbox(?) I hope that is right. I realise that I will lose programs but that is not a problem - they can be re-installed later. This method has been recommended as the easiest answer to this problem as I do not possess a disc for my factory installed Windows 7 I really hope you have the answer for me, John .
