ScheduledTask

Details of the scenario you tried and the problem that is occurring

Following the example in the documentation for disabling a built-in task I am receiving the error message that "The parameter is incorrect." at the 'Disabling' step. See below for more details:

Suggested solution to the issue

Review/Debug and correct what may be causing this error. In general it seems that the module is using the "Register-ScheduledTask" cmdlet, but perhaps in the case of disabling an exisiting task, the Set-TargetResource method should be using "Disable-ScheudledTask" instead?

The DSC configuration that is used to reproduce the issue (as detailed as possible)

Configuration MSIXHostSettings {

    Import-DscResource -ModuleName PsDesiredStateConfiguration
    Import-DscResource -ModuleName ComputerManagementDsc

    Node 'localhost' {

        ScheduledTask DisableWUScheduledStart {
            TaskName = "Scheduled Start"
            TaskPath = "\Microsoft\Windows\WindowsUpdate\"
            Enable = $false
        }
    }
}

Thanks for raising this @asmithgt .

This module does actually use Disable-ScheduledTask. See https://github.com/dsccommunity/ComputerManagementDsc/blob/master/source/DSCResources/DSC_ScheduledTask/DSC_ScheduledTask.psm1#L460

We do see the message Disabling existing scheduled task 'Scheduled Start' in '\Microsoft\Windows\WindowsUpdate'. in the logs you shared, so that would indicate that code is running.

I do notice that there appears to be a missing '\' at the end of the path shown in the logs. The DSC config you shared did include the '\'. This might be nothing but worth checking.
