AFAIK, WMI does not report items in the Task Scheduler, so by default Lansweeper is unable to report on them. Dynamic Groups will not filter that deep for sure.
If you have a specific scheduled task that you need to know is there, or not there as the case may be, then set up a Custom File Scan for it, and use reports to show you the results or to target deployments
Scheduled tasks can typically be found at Windows\System32\Tasks. This works for both Win7 and 10, both 32 & 64 bit.
As usual there are stock reports and examples that should help get you started.
