When viewing a computer under Manage > Computers, you may see many tasks that start with Execute WOL Compliance Task for MDP, followed by a GUID.
ITMS 8.x
This happens when you have a managed software delivery policy configured for Wake On LAN.
If you do not wish to have these WOL tasks created, you can simply disable them on the managed software delivery policy.
There is no concern about these tasks on the clients. If you would like to find what managed software delivery policies these tasks apply to, simply search your SQL database using the following query:
select * from vitem
where guid = 'Insert The GUID Shown under Jobs/Tasks'
