Windows Computer Management

We're continuing with Tools that are available through the System Configuration panel.

The Computer Management (compmgmt) utility has three primary sections: System Tools, Storage, and Services and Applications.

System Tools

Let's start with Task Scheduler. Per Microsoft, with Task Scheduler, we can create and manage common tasks that our computer will carry out automatically at the times we specify.

A task can run an application, a script, etc., and tasks can be configured to run at any point. A task can run at log in or at log off. Tasks can also be configured to run on a specific schedule, for example, every five mins.

To create a basic task, click on Create Basic Task under Actions (right pane).

 

Next is Event Viewer.

Event Viewer allows us to view events that have occurred on the computer. These records of events can be seen as an audit trail that can be used to understand the activity of the computer system. This information is often used to diagnose problems and investigate actions executed on the system.

Event Viewer has three panes.

1. The pane on the left provides a hierarchical tree listing of the event log providers. (as shown in the image above)
2. The pane in the middle will display a general overview and summary of the events specific to a selected provider.
3. The pane on the right is the actions pane.

There are five types of events that can be logged. Below is a table from docs.microsoft.com providing a brief description for each.


 

The standard logs are visible under Windows Logs. Below is a table from docs.microsoft.com providing a brief description for each.

Shared Folders is where you will see a complete list of shares and folders shared that others can connect to.

 

In the above image, under Shares, are the default share of Windows, C$, and default remote administration shares created by Windows, such as ADMIN$.


As with any object in Windows, you can right-click on a folder to view its properties, such as Permissions (who can access the shared resource).

Under Sessions, you will see a list of users who are currently connected to the shares. In this VM, you won't see anybody connected to the shares.

All the folders and/or files that the connected users access will list under Open Files.

The Local Users and Groups section you should be familiar with from Windows Fundamentals 1 because it's lusrmgr.msc.

In Performance, you'll see a utility called Performance Monitor (perfmon).

Perfmon is used to view performance data either in real-time or from a log file. This utility is useful for troubleshooting performance issues on a computer system, whether local or remote. 

Device Manager allows us to view and configure the hardware, such as disabling any hardware attached to the computer.

Storage  

Under Storage is Windows Server Backup and Disk Management. We'll only look at Disk Management.

Note: Since the virtual machine is a Windows Server operating system, there are utilities available that you will typically not see in Windows 10.  

Disk Management is a system utility in Windows that enables you to perform advanced storage tasks.  Some tasks are:

•     Set up a new drive
•     Extend a partition
•     Shrink a partition
•     Assign or change a drive letter (ex. E:)

Services and Applications

Recall from the previous task; a service is a special type of application that runs in the background. Here you can do more than enable and disable a service, such as view the Properties for the service.

 

WMI Control configures and controls the Windows Management Instrumentation (WMI) service.

Per Wikipedia, "WMI allows scripting languages (such as VBScript or Windows PowerShell) to manage Microsoft Windows personal computers and servers, both locally and remotely. Microsoft also provides a command-line interface to WMI called Windows Management Instrumentation Command-line (WMIC)."

Note: The WMIC tool is deprecated in Windows 10, version 21H1. Windows PowerShell supersedes this tool for WMI.

System Configuration

The System Configuration utility (MSConfig) is for advanced troubleshooting, and its main purpose is to help diagnose startup issues.

Reference the following document here for more information on the System Configuration utility.

There are several methods to launch System Configuration. One method is from the Start Menu.

Note: You need local administrator rights to open this utility.

The utility has five tabs across the top. Below are the names for each tab. We will briefly cover each tab in this task.

1.     General
2.     Boot
3.     Services
4.     Startup
5.     Tools

In the General tab, we can select what devices and services for Windows to load upon boot. The options are: Normal, Diagnostic, or Selective.

In the Boot tab, we can define various boot options for the Operating System. 

The Services tab lists all services configured for the system regardless of their state (running or stopped). A service is a special type of application that runs in the background.  

In the Startup tab, you won't see anything interesting in the attached VM.  Below is a screenshot of the Startup tab for MSConfig from my local machine.

As you can see, Microsoft advises using Task Manager (taskmgr) to manage (enable/disable) startup items. The System Configuration utility is NOT a startup management program.

Note: If you open Task Manager for the attached VM, you will notice that Task Manager doesn't show a Startup tab.

There is a list of various utilities (tools) in the Tools tab that we can run to configure the operating system further. There is a brief description of each tool to provide some insight into what the tool is for. 

Notice the Selected command section. The information in this textbox will change per tool.

To run a tool, we can use the command to launch the tool via the run prompt, command prompt, or by clicking the Launch button.




1) What is the name of the service that lists Systems Internals as the manufacturer?

Ans - PsShutdown




2) Whom is the Windows license registered to?

Ans - windows user



3) What is the command for Windows Troubleshooting?

Ans - C:\windows\system32\control.exe /name Microsoft.Troubleshooting




4) What command will open the Control Panel? (The answer is  the name of .exe, not the full path)

Ans - control.exe

Create Web API for CRUD operation

So ladies and gentlemen here we will create a new web application project in which GET, POST, PUT, and delete method will be used for CRUD operation.
 
So first we make one, for this you have to go to the file --> New --> Project then write on name section (whatever you want) and without disturbing the rest, you just clicked on the OK button.

 
and then you choose to MVC option in next tab and same as it as click on OK button.

So, as you can see this our project empty project is ready to launch on localhost...let's run first before write any code.
 

For this, Shortcut command press by keyboard


ctrl + F5

As you can see this here are displaying the project in browser by localhost

URL http://localhost:59322/

Add Models

So before proceeding here on the left side you are able to see some options, with the help of which we will create controller class, model class.
 

Wait, if your Solution Explorer not showing there, don't worry...follow to our steps.

Click on view --> Click Solution Explorer, Server Explorer option etc.

First we will create class and for this you have go to Models option and right click on this and go to Add --> class --> choose first option (Class) --> change the class name like in our case (class name is Student) and then click Add. button.

 

After creating a class then we write some code for generating a table name or attribute name like StudentID, StudentName

In Student.cs file -


So, write this command in your code...as it as same and don't forget to add LINE no 5 code (System.ComponentModel.DataAnnotations;)

[Key]
public int StudentID { get; set; }
public string StudentName { get; set; }

NOTE - The get method returns the value of the variable name . The set method assigns a value to the name variable. The value keyword represents the value we assign to the property.
 

Then go to IdentityModels.cs file write this command also.
 

public DbSet <Student> Student { get; set; }

Save all file (ctrl + s).
 

Before diving into long sea..let's build first and create a migrations, add migrations and update-database.


For this Click on Build --> Build Solution
 

Then,

Go to Tools --> NuGet Package Manager --> Package Manager Console
 

enable-migrations 

And at the same time you are able to see that the file is being created inside the migrations.
 

add-migration init 

update-database

• The Enable-Migration command creates the Migrations folder, which contains a script to initialize the database. 
•  
  
• (init is a migration name)
•  
• Update the database for any kind of changes

Now, after updating the database as you can see this in Server explorer section

Data connection --> Tables --> Table name (in our case Students is table name).

 

Add Web API Controller

So before proceeding here on the left side you are able to see some options, with the help of which we will create controller class, model class.

For create a Controller class right click on controller --> Add --> choose Controller option.
 

 

Choose MVC 5 Controller - Empty and then click on Add button.

This will open Add Scaffold popup as shown below.

 

Attention Please in Add Controller popup tab, here Controller name is DefaultController. So, Remove "Default" word and type any name whatever you want (in our case we are going to write "Student") then click on Add button.

 


In StudentController.cs file write some code for doing a CRUD operation... but first we are doing a Create operation.

Type this command -

[HttpPost]
public ActionResult Create(Student s)
        {
         ApplicationDbContext db = new ApplicationDbContext();
         db.Student.Add(s);
         db.SaveChanges();
         return View();
        }

If in case any error are there like this shown below, then tension we are here for your help.

Simple mouse click on this red line error and as you can see that A yellow light bulb appear here so click on little arrow and choose "using WebApplication2.Models; (In your case this name may be different, don't worry)

Hurray Error is gone :-) :-p


and "using WebApplication2.Models;" line is added on StudentController.cs file. DONE

Hurray Error is gone :-) :-p

and "using WebApplication2.Models;" line is added on StudentController.cs file. DONE
 

Now, we will create a Add view. So, for this you have to right click on "Create" --> Add view --> and choose the correct all option as it as same.

then Click on Add button.

This will open Add Scaffold popup as shown below.

In solution explorer, there are appear Create.cshtml file.

and finally we will run.

ctrl + F5

or

Click on Middle top side Green color button...click on it.

public ActionResult Display()
        {
            ApplicationDbContext db = new ApplicationDbContext();
            var lst = db.Student.ToList();
            return View(lst);
        }
        public ActionResult Details(int id)
        {
            ApplicationDbContext db = new ApplicationDbContext();
            var s = db.Student.Where(x => x.StudentID == id).SingleOrDefault();
            return View(s);
        }

Please Be Patience We Will Update Very Soon :-)
