Device protection in Windows Security

Windows Security provides the following built-in security options to help protect your device from malicious software attacks.

To access the features described below, in the search box on the taskbar, type windows security, select it from the results, and then select Device security.

Notes: What you actually see on the Device security page may vary depending upon what your hardware supports.

For more info about Windows Security, see Stay protected with Windows Security.

For more info about Microsoft Defender Firewall, see Turn Microsoft Defender Firewall on or off.

Core isolation

Core isolation provides added protection against malware and other attacks by isolating computer processes from your operating system and device. Select Core isolation details to enable, disable, and change the settings for core isolation features.

Memory integrity

Memory integrity is a feature of core isolation. By turning on the Memory integrity setting, you can help prevent malicious code from accessing high-security processes in the event of an attack.

Security processor

Your security processor provides additional encryption for your device.

Security processor details

This is where you’ll find info about the security processor manufacturer and version numbers, as well as about the security processor’s status. Select Security processor details for additional info and options.

Note: If you don’t see a Security processor entry on this screen then it’s likely that your device doesn’t have the TPM (Trusted Platform Module) hardware necessary for this feature.

If your security processor isn’t working properly you’ll see a link on the Security processor details page that says Security processor troubleshooting. Select it to see any error messages and advanced options. For more information see: Security Processor troubleshooting.

Secure boot

Secure boot prevents a sophisticated and dangerous type of malware—a rootkit—from loading when you start your device. Rootkits use the same permissions as the operating system and start before it, which means they can completely hide themselves. Rootkits are often part of an entire suite of malware that can bypass local logins, record passwords and keystrokes, transfer private files, and capture cryptographic data.

You may have to disable secure boot to run some PC graphics cards, hardware, or operating systems such as Linux or earlier versions of Windows. For more info, see How to disable and re-enable secure boot.

Hardware security capability

At the bottom of the Device security screen, one of the following messages appears, indicating the security capability of your device.

Your device meets the requirements for standard hardware security

This means your device supports memory integrity and core isolation and also has:

TPM 2.0 (also referred to as your security processor)

Secure boot enabled

Your device meets the requirements for enhanced hardware security

This means that in addition to meeting all the requirements of standard hardware security, your device also has memory integrity turned on.

Your device exceeds the requirements for enhanced hardware security ( Note: In Windows 20H2 this message will say «Your device has all Secured-core PC features enabled»)

This means that in addition to meeting all the requirements of enhanced hardware security, your device also has System Management Mode (SMM) protection turned on.

Standard hardware security not supported

This means that your device does not meet at least one of the requirements of standard hardware security.

Improving hardware security

If the security capability of your device isn’t what you’d like it to be, you might need to turn on certain hardware features (such as secure boot, if supported) or change the settings in your system’s BIOS. Contact your hardware manufacturer to see what features are supported by your hardware and how to activate them.

Stay protected with Windows Security

Windows 10 includes Windows Security, which provides the latest antivirus protection. Your device will be actively protected from the moment you start Windows 10. Windows Security continually scans for malware (malicious software), viruses, and security threats. In addition to this real-time protection, updates are downloaded automatically to help keep your device safe and protect it from threats.

Windows 10 in S mode

Some features will be a little different if you’re running Windows 10 in S mode. Because this mode is streamlined for tighter security, the Virus & threat protection area has fewer options. But don’t worry—the built-in security of this mode automatically prevents viruses and other threats from running on your device, and you’ll receive security updates automatically. For more info, see Windows 10 in S mode FAQ.

Important security info

Windows Security is built-in to Windows 10 and includes an antirvirus program called Microsoft Defender Antivirus. (In previous versions of Windows 10, Windows Security is called Windows Defender Security Center).

If you have another antivirus app installed and turned on, Microsoft Defender Antivirus will turn off automatically. If you uninstall the other app, Microsoft Defender Antivirus will turn back on automatically.

If you’re having problems receiving Windows Security updates, see Fix Windows Update errors and the Windows Update FAQ.

For info on how to uninstall an app, see Repair or remove an app in Windows 10.

To change your user account to an admin account, see Create a local user or administrator account in Windows 10.

Understand and customize Windows Security features

Windows Security is your home to manage the tools that protect your device and your data:

Virus & threat protection. Monitor threats to your device, run scans, and get updates to help detect the latest threats. (Some of these options are unavailable if you’re running Windows 10 in S mode.)

Account protection. Access sign-in options and account settings, including Windows Hello and dynamic lock.

Firewall & network protection. Manage firewall settings and monitor what’s happening with your networks and internet connections.

App & browser control. Update settings for Microsoft Defender SmartScreen to help protect your device against potentially dangerous apps, files, sites, and downloads. You’ll have exploit protection and you can customize protection settings for your devices.

Device security. Review built-in security options to help protect your device from attacks by malicious software.

Device performance & health. View status info about your device’s performance health, and keep your device clean and up to date with the latest version of Windows 10.

Family options. Keep track of your kids’ online activity and the devices in your household.

You can customize how your device is protected with these Windows Security features. To access them, select Start > Settings > Update & Security > Windows Security . Then select the feature you want to explore.
Open Windows Security settings

Status icons indicate your level of safety:

Green means your device is sufficiently protected and there aren’t any recommended actions.

Yellow means there is a safety recommendation for you.

Red is a warning that something needs your immediate attention.

Run a malware scan manually

When you’re concerned about risks to a specific file or folder, you can right-click the file or folder in File Explorer, then select Scan with Microsoft Defender.

If you suspect there’s malware or a virus on your device, you should immediately run a quick scan. This is much faster than running a full scan on all your files and folders.

Run a quick scan in Windows Security

Select Start > Settings > Update & Security > Windows Security and then Virus & threat protection.
Open Windows Security settings

Under Current threats, select Quick scan (or in previous versions of Windows 10, under Threat history, select Scan now).

If the scan doesn’t find any issues, but you’re still concerned, you may want to check your device more thoroughly.

Run an advanced scan in Windows Security

Select Start > Settings > Update & Security > Windows Security and then Virus & threat protection.

Under Current threats, select Scan options (or in previous versions of Windows 10, under Threat history, select Run a new advanced scan).

Select one of the scan options:

Full scan (check files and programs currently running on your device)

Custom scan (scan specific files or folders)

Microsoft Defender Offline scan (run this scan if your device has been, or could potentially be, infected by a virus or malware). Learn more about Microsoft Defender Offline

Select Scan now.

Note: Because of streamlined security, this process isn’t available if you’re running Windows 10 in S mode.

Schedule your own scan

Even though Windows Security is regularly scanning your device to keep it safe, you can also set when and how often the scans occur.

Schedule a scan

Select the Start button, type schedule tasks in the Search box, and in the list of results, select Task Scheduler.

In the left pane, select the arrow (>) next to Task Scheduler Library to expand it, do the same with Microsoft > Windows, and then scroll down and select the Windows Defender folder.

In the top-center pane, select Windows Defender Scheduled Scan. (Point to the choices to see the full names.)

In the Actions pane on the right, scroll down and then select Properties.

In the window that opens, select the Triggers tab, and then select New.

Set your preferred time and frequency, and then select OK.

Review the schedule and select OK.

Note: Because of streamlined security, this process isn’t available if you’re running Windows 10 in S mode.

Turn Microsoft Defender Antivirus real-time protection on or off

Sometimes you may need to briefly stop running real-time protection. While real-time protection is off, files you open or download won’t be scanned for threats. However, real-time protection will soon turn on automatically again to protect your device.

Turn real-time protection off temporarily

Select Start > Settings > Update & Security > Windows Security and then Virus & threat protection > Manage settings. (In previous versions of Windows 10, select Virus & threat protection > Virus & threat protection settings.)
Open Windows Security settings

Switch the Real-time protection setting to Off and choose Yes to verify.

Note: Because of streamlined security, this process isn’t available if you’re running Windows 10 in S mode.
