Here's how to Run Scheduled Task when an Event is triggered in Windows.

i. To run a scheduled task after another task completes, you can use the **Start a task after a task completes** trigger. This trigger allows you to specify the name of the task that you want to run after the first task completes.

To use the **Start a task after a task completes** trigger, follow these steps:

1. Open Task Scheduler.
2. In the left pane, expand **Task Scheduler Library**.
3. Right-click **Tasks** and select **New Task**.
4. In the **General** tab, enter a name and description for the task.
5. In the **Triggers** tab, select **Start a task after a task completes**.
6. In the **Task** field, enter the name of the task that you want to run after the first task completes.
7. In the **Conditions** tab, specify any conditions that you want to meet before the task runs.
8. In the **Actions** tab, specify the actions that you want the task to perform.
9. Click **OK** to create the task.

Once you have created the task, it will be scheduled to run after the first task completes. If the first task fails to run, the second task will not run.

Here are some examples of how you can use the **Start a task after a task completes** trigger:

* You can use the trigger to run a backup task after a file synchronization task completes. This will ensure that your files are backed up even if the file synchronization task fails.
* You can use the trigger to run a notification task after a software update task completes. This will notify you that the software update has been installed.
* You can use the trigger to run a cleanup task after a data migration task completes. This will ensure that any temporary files are deleted after the data migration is complete.

The **Start a task after a task completes** trigger is a powerful tool that can be used to automate a variety of tasks. By using this trigger, you can save time and effort by automating tasks that you would otherwise have to perform manually.

ii. There are a few ways to force a task to run in Task Scheduler.

**Method 1: Run the task manually**

You can manually run a task by opening Task Scheduler and right-clicking the task and selecting "Run".

**Method 2: Use the "Run" command**

You can also use the "Run" command to run a task. Open a command prompt and type the following command:

```
schtasks /RUN /TN "TaskName"
```

Replace "TaskName" with the name of the task that you want to run.

**Method 3: Use the Task Scheduler API**

You can also use the Task Scheduler API to force a task to run. This is the most flexible method, but it also requires the most technical knowledge.

To use the Task Scheduler API, you will need to create a C# or VB.NET application. You can then use the TaskScheduler class to force the task to run.

Here is an example of how to force a task to run using the TaskScheduler class in C#:

```
using System;
using System.Threading.Tasks;
using System.Management;

namespace ForceTask
{
class Program
{
static void Main(string[] args)
{
// Get the TaskScheduler object.
TaskScheduler scheduler = TaskScheduler.FromCurrentSynchronizationContext();

// Get the task name.
string taskName = "TaskName";

// Force the task to run.
scheduler.Run(taskName);
}
}
}
```

Here is an example of how to force a task to run using the TaskScheduler class in VB.NET:

```
Imports System
Imports System.Threading.Tasks
Imports System.Management

Namespace ForceTask

Public Class Program

Public Shared Sub Main(ByVal args() As String)

' Get the TaskScheduler object.
Dim scheduler As TaskScheduler = TaskScheduler.FromCurrentSynchronizationContext()

' Get the task name.
Dim taskName As String = "TaskName"

' Force the task to run.
scheduler.Run(taskName)

End Sub

End Class

End Namespace
```

iii. The error code 0xc0000005 in Task Scheduler means that the task failed to run due to a general access violation. This can happen for a variety of reasons, such as:

* The task is trying to access a file or folder that it does not have permission to access.
* The task is trying to execute code that is not compatible with the current operating system.
* The task is trying to access a resource that is already in use.

To fix this error, you will need to identify the specific reason why the task is failing. Once you have identified the reason, you can take steps to fix the problem. For example, if the task is trying to access a file or folder that it does not have permission to access, you can grant the task the appropriate permissions.

If you are unable to fix the error, you can contact the developer of the task for assistance.
