For the last one month i.e. after June 2014 windows updates Automatic Maintenance feature has stopped running its natural course, therefore my doubt says that one of the windows update must have affected this windows feature but which update? I'm totally unaware of that. Even if I try to run it manually, it stays on for a while & then it stops abruptly, leaving a nagging message, "The automatic maintenance was delayed. Maintenance tasks will run at the next scheduled time, or you can run maintenance now." I've tried to resolve this issue by tweaking the settings in the scheduled tasks in maintenance folders but to of no avail. I've also tried following some suggestions on the net but everything in vain. I seek help on this issue from anyone & everyone, please help.
