I'm just having a problem with the scheduled tasks not running, if I start them manually there is no problem. But they won't start automatically. E.g. when I just started Windows Defender, it was complaining that the computer hasn't been scanned for 21 days and recommending a daily scheduled scan... But there IS a daily scheduled scan, it is the default one which is preinstalled, it just seems to be nonfunctional. It is set to run at 5:36am, all the default settings are intact (they are greyed out so cannot be changed), e.g. it is set to run ASAP if scheduled start is missed, and everything shows as being enabled and ready, the next run time even changes every day to show to next day's date, however the task simply does not run and under the last run time it just says "never". Ditto for the disk defrag task. Seems quite mysterious.
