Workaround: Overwrite install or reinstall.

3 Timing software or scheduled task software works.

If you set up in the Schedule Taskbar to restart or load certain workers, the computer will start up again when the scheduled time comes. In this case, we can open the "startup" item, check whether there are any executable files or other scheduled workers that we are not familiar with, block them and then boot them to check. Of course, we can also directly enter the "msconfig" command in "Run" to select the startup item.
