Защитник в операционной системе Windows 10 — стандартное средство, обеспечивающее безопасность во время взаимодействия со сторонними файлами и программами. Иногда пользователям требуется обратиться к настройкам этого компонента, например, чтобы активировать его или отключить. В таких случаях нужно запустить графическое меню, где и осуществляются все конфигурации. Далее мы хотим обсудить именно эту тему, продемонстрировав доступные варианты перехода к редактированию Защитника.
Способ 1: Поиск в меню Пуск
Самый простой метод — отыскать необходимое меню через встроенную в меню Пуск строку поиска. Для этого нужно лишь нажать по соответствующей кнопке и начать вписывать запрос. При отображении подходящего результата «Безопасность Windows» щелкните по нему левой кнопкой мыши, чтобы открыть меню.
Способ 2: Меню Параметры
Как известно, Защитник Виндовс в последней версии располагается в отдельном разделе меню Параметры, поэтому основной метод перехода к данному компоненту и осуществляется через эту оснастку. Сделать это можно следующим образом:
- Нажмите по кнопке «Пуск» и перейдите в «Параметры», щелкнув по значку в виде шестеренки.
- Здесь вам нужен последний пункт «Обновление и безопасность».
- Воспользуйтесь панелью слева, чтобы переместиться в «Безопасность Windows».
- Нажмите на «Открыть службу «Безопасность Windows»» или самостоятельно перейдите к областям защиты, выбрав подходящий пункт в списке.
- Теперь вы можете перейти к управлению защитой операционной системы. Разобраться в этом поможет краткий обзор безопасности, представленный на главной странице службы.
Способ 3: Панель управления
Разработчики Windows 10 активно занимаются переносом параметров из привычного многим меню Панель управления в Параметры. Однако сейчас там все еще можно найти множество полезных оснасток и опций, что относится и рассматриваемому сегодня Защитнику. Его открытие осуществляется следующим образом:
- Откройте меню Пуск и через поиск отыщите приложение «Панель управления».
- Здесь вас интересует раздел «Центр безопасности и обслуживания».
- В появившемся окне разверните категорию «Безопасность».
- Щелкните по надписи «Просмотреть в службе «Безопасность Windows»» возле необходимого параметра.
- После этого сразу же будет открыто окно и вы можете приступить к конфигурации нужных опций.
Способ 4: Исполняемый файл Защитника Windows 10
Этот способ, как и рассмотренный далее, позволяет лишь запустить саму службу безопасности, при этом не попадая в увиденное ранее графическое меню. Данный вариант подойдет тем пользователям, кто заинтересован во введении данной службы в режим активного функционирования. Осуществляется это при помощи соответствующего исполняемого файла.
- Откройте Проводник и переместитесь к системному разделу жесткого диска.
- Тут откройте директорию «Program Files».
- В ней отыщите каталог «Windows Defender».
- Остается только запустить файл «MpCmdRun», дважды кликнув по нему левой кнопкой мыши.
После этого буквально на секунду отобразится окно консоли, а затем оно будет автоматически закрыто. Теперь служба работает и должно начаться автоматическое сканирование на вирусы, если оно было запланировано.
Способ 5: Утилита Выполнить
Последний метод нашей сегодняшней статьи практически идентичен упомянутому выше, однако само действие выполняется буквально в несколько кликов. Для этого придется запустить утилиту Выполнить клавишами Win + R и ввести там С:\Program Files\Windows Defender\MpCmdRun.exe. После нажатия по клавише Enter служба будет автоматически запущена точно таким же образом, как это было показано ранее.
После запуска Защитника в Виндовс 10 каждому пользователю нужно выполнить в данном меню ряд разных действий, например, активировать его, отключить или добавить исключения. Разобраться в этом помогут отдельные материалы на нашем сайте. Перейти к ним можно, нажав по ссылкам ниже.

Once you complete the steps, the items will be restored in the original or alternate location, depending on the command.
This guide focuses on the more important commands you can use with Command Prompt, but the tool includes additional options, which you can view running the
MpCmdRuncommand.
While you can manage a number of functions through Command Prompt, the tool is quite limited. For example, you cannot start an offline scan or change preferences. If you want to manage settings and control virtually every aspect of Microsoft Defender Antivirus with commands, you should be using the PowerShell modules instead.

Windows Security, formerly known as Microsoft Defender, is the go-to app for those who want to know more about security in Windows 10 and Windows 11. This app is part of Microsoft’s operating system, and this is where you can find out what your antivirus has been doing, what your firewall has to say, and whether other security features are turned on and working well. However, before you can get any information, you must know how to access Windows Security. That’s why, in this article, I show you several ways to open Windows Security in Windows 10 and Windows 11:
1. Where to find Windows Security in the system tray
By default, Windows Security is started automatically by Windows, and it runs in the background, protecting your computer or device. Few people know that you can find its icon in the system tray (the bottom-right corner of the taskbar) in Windows 11 and Windows 10.
Click or tap the arrow pointing upwards to Show hidden icons, and then, in the list of icons, click or tap the blue shield. If you hover your mouse over it, it says Microsoft Defender. Don’t worry, it’s just another name for Windows Security.
Opening Windows Security from the system tray in Windows 11
In Windows 10, the process is identical, even though things look a little different. The main difference is that the Windows Security icon is a white shield instead of a blue one.

Keep in mind that Windows Security displays an exclamation mark alongside its icon when it finds issues that require your attention, similar to the screenshot above.
2. Open Windows Security from the command line (CMD, PowerShell, Terminal)
Some people who work with Windows Security need to find a way to open it from a command-line app like the Command Prompt, PowerShell, or Windows Terminal. Open any of these apps on your Windows computer, type this command, and press Enter:
start windowsdefender:
Here’s me running it in the Windows Terminal from Windows 11:

In the screenshot below, I’ve started CMD and ran the same command in Windows 10:
Opening Windows Security from CMD
TIP: If your computer is having issues loading Windows, here’s how to open Command Prompt when Windows doesn’t boot.
3. How to access Windows Security from the Start Menu
A simple way of accessing Windows Security is from the Start Menu. In Windows 10, click or tap Start, scroll down through the list of apps until you find those that start with the letter W, and then choose the Windows Security shortcut.

In Windows 11, things are a bit different: click or tap Start followed by All apps. Then, in the list of apps, scroll to the bottom, find the Windows Security shortcut, and tap on it.

4. How to create a Windows Security shortcut on your desktop
After finding the Windows Security shortcut in the Start Menu (using the instructions from the previous section), you can drag and drop it to the desktop. If you execute the move correctly, a Link text and the Windows Security shortcut accompany your cursor as you move it across the desktop. Release the left mouse button (or lift your finger from the touchscreen) anywhere on the desktop, and Windows 10 creates a new shortcut right there.
Creating a Windows Security shortcut on the Windows 10 desktop
In Windows 11, it’s just as easy to create a Windows Security shortcut on the desktop using the Start Menu. Find the Windows Security shortcut in the All apps list, click or press and hold on it, and then move the mouse (or your finger) outside the Start Menu somewhere on the desktop. When you see the Link text alongside the shortcut, release the mouse or lift your finger, and the shortcut is created.
Creating a Windows Security shortcut on the Windows 11 desktop
You can also create a Windows Security shortcut using the Create Shortcut wizard. Right-click (or press and hold) on the empty space on your desktop and choose New > Shortcut. Then, copy and paste or type the following as your target location:
windowsdefender:
You can also use this target:
%windir%\explorer.exe windowsdefender:
Click or tap Next, name the shortcut Windows Security, and press Finish.
Creating a Windows Security shortcut
Keep in mind that the first target that I provide creates a shortcut using the default Windows Security icon, while the second uses the File Explorer icon.
5. How open Windows Security with a keyboard shortcut
If you’ve created a Windows Security shortcut on the desktop by dragging it from the Start Menu, as shown in this guide’s fourth method, you can then edit the shortcut’s Properties in order to open this app with a keyboard shortcut. After creating the shortcut on the desktop, right-click (or press and hold) on it and choose Properties.
Accessing the Properties of the Windows Security shortcut
Next, click or tap inside the Shortcut key text box and press the shortcut key combination you want to use to open this app. For example, you could press CTRL + ALT + W, like I did in my screenshot. When you’re done setting up the shortcut key, press OK.
Setting the shortcut key for Windows Security
This method works the same in Windows 10 and Windows 11. If you need more information, read this guide: How to open any program (or app) with a keyboard shortcut in Windows.
6. How to open Windows Security with Run
An old-school way of opening apps in Windows is through the Run dialog. Press Windows + R on your keyboard, and in the Open field, type:
windowsdefender:
Don’t forget to press Enter on your keyboard or click/tap OK to execute your command and open Windows Security.

7. How to find Windows Security using search
People who are wondering where to find Windows Security on their Windows computer can always use search. It’s a fast and reliable way of opening apps.
If you’re using Windows 10, click or tap inside the Search box on the taskbar, type the word security, and choose the Windows Security search result.
Accessing Windows Security via search in Windows 10
If you’re using Windows 11, finding Windows Security works exactly the same way. However, remember that the search feature may not always display Windows Security as the first search result on the list. It may also display folders with this name or apps like those in the screenshot below.

8. How to start Windows Security from File Explorer
Few people know that File Explorer offers another convenient way to start Windows Security. Open File Explorer and type or copy and paste this command in its address bar:
windowsdefender:
Then, press Enter on your keyboard to execute it.🙂

9. Pin Windows Security on your taskbar or Start Menu
Locate the Windows Security shortcut in the Start Menu. As shown in method 3, in Windows 10, you can find this shortcut at the bottom of the apps list. Then, right-click or press and hold Windows Security, and a contextual menu appears. The first option in the menu is Pin to Start, which pins the Windows Security shortcut in the Start Menu. If you choose More, an extension opens, allowing you to Pin to taskbar.
Pinning Windows Security to the Start Menu or the taskbar in Windows 10
The steps are similar in Windows 11. However, you first need to click or tap Start, followed by All apps, to see the list of apps installed on your computer. Then, right-click (or press and hold) the Windows Security shortcut and pin it where you want.

10. How to open Windows Security using Settings
If you’re already using the Settings app and need to access Windows Security, you can do that really quickly:
Open Settings and go to the Update & Security category. On the left side of the window, select Windows Security; then, on the right, click or tap Open Windows Security.
Open Windows Security from the Windows 10 Settings
If you’re using Windows 11, open the Settings app (Windows + I) and choose Privacy & security on the left. On the right side of the window, click or tap Windows Security, followed by Open Windows Security.
Open Windows Security from the Windows 11 Settings
11. Start Windows Security from Task Manager
If you’re using Task Manager to view running apps and processes, and you need to bring up Windows Security, you can do that straight from this app, like this:
In Windows 10, open Task Manager (a quick way is to press the Control + Shift + Escape keys simultaneously). If you get the compact view of the Task Manager, click or tap on More details. Next, click or tap File > Run new task.
In Task Manager go to File > Run new task
In the Create new task window, type or copy and paste this command in the address bar:
windowsdefender:
Don’t forget to press Enter or click or tap OK.
Run Windows Security from Task Manager
This process no longer works in Windows 11 because the Task Manager has been completely revamped, and it no longer gives you access to the Create new task window, like it does in Windows 10.
What is your preferred way of accessing Windows Security?
This is a lengthy tutorial that aims to provide you with as complete information as possible. Most people need to know a method or two for opening Windows Security, while others may have to experiment with most of the methods I detailed and then choose the one that suits their needs. Regardless, let me know which works best for you and why. How do you access Windows Security on your Windows 10 or Windows 11 computer?
