delete scheduled task: %s (%w)

Error message

delete scheduled task: %s (%w)

What it means

deleteWindowsTask wraps an error from runPowerShell running its Unregister-ScheduledTask script. The script exits 0 silently if the task does not exist, so this error means Unregister-ScheduledTask actually failed (or the PowerShell exec itself failed).

Solutions

1. Read the %s output in the error for the exact Unregister-ScheduledTask failure.
2. Delete the task manually: `Unregister-ScheduledTask -TaskName <name> -Confirm:$false` in an elevated PowerShell.
3. Stop the task first (`Stop-ScheduledTask`) if it is running and locked.
4. Run the uninstall as the user who owns the task, or with elevation.

Example fix

// manual cleanup when Unregister fails
Stop-ScheduledTask -TaskName cc-connect -ErrorAction SilentlyContinue
Unregister-ScheduledTask -TaskName cc-connect -Confirm:$false

out, _ := exec.Command("powershell", "-NoProfile", "-Command",
	"(Get-ScheduledTask -TaskName '<name>').State").Output()
if strings.TrimSpace(string(out)) == "Running" {
	exec.Command("powershell", "-NoProfile", "-Command",
		"Stop-ScheduledTask -TaskName '<name>'").Run() // stop before uninstall
}

if err := daemon.Uninstall(); err != nil {
	if strings.Contains(err.Error(), "delete scheduled task") {
		slog.Warn("task deletion denied; try elevated PowerShell: Unregister-ScheduledTask -TaskName <name> -Confirm:$false", "error", err)
	}
}

When it happens

Trigger: Called by Install (when trying to remove a stale task before recreating it) and Uninstall on Windows, when Unregister-ScheduledTask -Confirm:$false returns an error: access denied, task owned by another user, task currently running/locked, or powershell.exe exec failure.

Common situations: Uninstalling a task created by another Windows account; insufficient privileges (task registered with elevated RunLevel); the task is running and locked; enterprise policy forbids task deletion.
