Windows 8 just notified me to run the Automatic Maintenance in the "Action Center". But what is that and what is it doing?

You can do it by task scheduler. For this open the task scheduler by typing task on the Modern UI under the Apps and you will find the Task Scheduler at the left side click it and open. Now go to following path
Task Scheduler > Microsoft > Windows > Task Scheduler
Here you have to right click on the Idle Maintenance & Regular Maintenance and select the option disable, that's it!
If you want to enable it again then just do the reverse.
This finally stopped when I updated to Windows 8.1.

According to official msdn site
http://msdn.microsoft.com/en-us/library/windows/desktop/hh848037(v=vs.85).aspx
Automatic maintenance regularly checks for solutions to problems (via Windows Error Report), runs the .NET Optimization Service and defrags all hard disks automatically -- all of this happens while the PC is on idle, of course.
If your computer is in Sleep mode, while on AC Power, it will be resumed and the maintenance activity will be carried out using full system resources to execute the task as fast as it can. After completion of the task, the system will be returned to Sleep mode. You will however, have to check the Allow scheduled maintenance to wake up my computer, if it is plugged in at the scheduled time option.
When Automatic Maintenance is being run, you will see its indication in the taskbar icon.
