How can I run a schedule task from UWP app on Windows 10 iot Core?

Question

System: Windows 10 IoT Core (10.0.17763.1577)

Request: I would like to run a task from UWP app with ProcessLauncher.RunToCompletionAsync method.

Description: I use "schtasks.exe" command from code if I call with ProcessLauncher this command "c:\windows\system32\schtasks.exe", "/query" working perfect.
But If would like to call "c:\windows\system32\schtasks.exe", "/run /TN \"UWFEnable\"", I receive this output: ERROR: Access is denied.

In my opinion UWP app run as Defaultaccount, that's why I have to add schedule task run permission. I tried to add DefaultAccount to Administrators group, but i received this error message: "Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE))\n at System.StubHelpers.StubHelpers.GetWinRTFactoryObject(IntPtr pCPCMD)\r\n at Windows.System.ProcessLauncher.RunToCompletionAsync(String fileName, String args, ProcessLauncherOptions options)\r\n at System.Cmd.Command.RunProcess(String Command, String Arguments)\n"

How can i run a schedule task from UWP app? And what permissions necessary to DefaultAccount? What kind of powershell command necessary?

Hi @IntelliSense ,

First of all, this is an article about the various commands of Task Scheduler and here is the Microsoft doc.
Please see this link which is a similar thread: where you can see if any steps are missing.
In addition, please try to provide Everyone group Full permission in the Task path.
Have you tried using schtasks /Change /TN "<task name>" /Enable？
