I echo some of above. Sceduling is no good as most of us switch off our computers a lot of the time. XP was informative, simple and user friendly re disk defrag. I am now having to leave laptop computer ( with vista) on after having clicked defrag as there is no way of me knowing if the disk needs it and no way of knowing how much progres the process has made. Would love to ditch vista for this and many other resaons but my new laptop came with it and thank god I have desktop with Xp so that I can use IE to troubleshoot Vista
