Yes, yes it is!
I had to do some digging. The first part of this is to make sure that you have the right audit policies in place on your machine or in your domain. The category in Windows 7/8/2008 is "Other Object Access Events." I was able to enable this on my local machine with the command:
auditpol /set /subcategory:"Other Object Access Events" /failure:enable /success:enable
Once that was done, I launched Task Scheduler and was able to get the following events in my LEM:
ProcessInfo Scheduled Task "\My Tasks\Sample" Deleted Vista Security Microsoft-Windows-Security-Auditing 4699 ProcessInfo Scheduled Task "\My Tasks\Sample" Enabled Vista Security Microsoft-Windows-Security-Auditing 4700 ProcessInfo Scheduled Task "\My Tasks\Sample" Disabled Vista Security Microsoft-Windows-Security-Auditing 4701 ProcessInfo Scheduled Task "\My Tasks\Sample" Created by "DOMAIN\UserName" Vista Security Microsoft-Windows-Security-Auditing 4698
As you can see, events were generated for the event being created, disabled, enabled, and deleted. That should just about cover what you're looking for, right? Obviously, the LEM would add the source account and machine, but I trimmed this to make it fit the post, and I didn't think that information was relevant to the answer.
