Task scheduler - can I delete th files

When I open task scheduler I am getting errors of missing files. They are not so easy to find in the task library.

When I go to Options I am given the option to delete the files ( part of disk clean up).

Is this safe? I gather doing will mean that I will have to reconfigure most of the tasks though would like to hope that a given program will reconfigure for me.

What do the error messages say?

You can delete what Windows Disk Cleanup reports, but I am not seeing where that ties in with your Task Scheduler problem.
