Resolved Task Scheduler check box disabled

I am tryin to change the sttings on my weekly virus scan in the taxk scheduler. The scan is set up but the check box for "Run task as soon as possible after start is missed" is unchecked and disabled. As a result, the computer is never getting scanned as it seems to miss the scheduled start each time.

I have this set up on other computers without a problem but I don't know how to enable this instruction.

I would have set the task to wake up the computer to run but I have had to disbale the wake timers as the computer was waking frequently on an ad hoc basis.

Again, I have the wake timers disabled on the other computers and the instruction tp run the task works fine; it is just that that cannot be enabled on this one computer.

 

I think it is because there is no password on the usre id.
