High cpu usage when idle, win 8

If you find your fan is noisy while idle, M$ may run its famous auto maintenance without your permission. This auto maintenance may be turned on "automatically" during the system update. I do not know why M$ likes it so much.


The following is the way to turn it off.



1. Press the + R keys to open the Run dialog, type taskschd.msc, and click/tap on OK.

2. In the left pane of Task Scheduler, click/tap on to expand Task Scheduler Library, Microsoft, Windows, and TaskScheduler. (see screenshots below)

3. In the middle pane of TaskScheduler, either right click on or select the Regular Maintenance task, and do step 4 or 5 below for what you would like to do. (see screenshots below)
