To solve my original question on page one of this thread I have uninstalled Diskeeper 10 Professional. Windows defrager has now put itself back in start/accessories/systemtools. SO way back before buying Diskeeper 10 Professional I was advised not to. This has all been a learning curve for me. The best lesson I have learned is - if I ask for an opinion, when given, take the advice in most cases. I should have listened to my learned advisors point of view earlier. Thanks
