Solution:

This problem is the windows planning service. Just shut it down

Win7 system cancels the scheduled task schedule of MySQL in control panel, all control panel items, management tools and task scheduler (XP in start/attachment/system tools/task schedule)

Find the corresponding task in the task plan library and right-click to select disable
