Got dell desktop and running windows 7. Flag icon at the right bottom has an red x on it. click on it and says important message .Says need to change windows update settings. Try to change settings and nothing happens. Went to windows update. Takes a long time to open. Then when finally opens. I try to change settings and won't do anything. Never had problem before and always has worked. Says things like service not running. When i get to windows updates a red x shows. Any suggestions? Thank you
