Check Health Report in Windows 11

To help you keep your device secure, Windows Security monitors your device for security issues and provides a health report, which appears on the Device performance & health page. The Health report alerts you to common issues in four key areas and offers recommendations to remedy them.

The Health report starts off by showing you the last time a Device Health scan was run. The time displayed should be basically the current time, as Windows Security tries to run a Device Health scan when you open the Device performance & health page.

Beyond the time of last scan you’ll see the status of the key areas that Device Health monitors:

  • Storage capacity – Is your system running low on disk space?
  • Apps and software – Is any of your software failing, or in need of an update?
  • Battery life – Is anything putting an extra strain on your PC’s battery? You might not see this on on a desktop PC that is always plugged in.
  • Windows Time service – Having your system set to the correct time is important for a lot of system processes. Windows Time service automatically synchronizes your system clock to an internet-based time service so your system time is always correct. If this service is off, or failing, Device performance & health will let you know so you can fix it.

This tutorial will show you how to check your device performance and health report in Windows 11.

Enable or Disable Core Isolation Memory Integrity in Windows 11

Core isolation is a security feature of Microsoft Windows that protects important core processes of Windows from malicious software by isolating them in memory. It does this by running those core processes in a virtualized environment.

Memory integrity, also known as Hypervisor-protected Code Integrity (HVCI) is a Windows security feature that makes it difficult for malicious programs to use low-level drivers to hijack your computer.

A driver is a piece of software that lets the operating system (Windows in this case) and a device (like a keyboard or a webcam, for two examples) talk to each other. When the device wants Windows to do something it uses the driver to send that request.

Memory integrity works by creating an isolated environment using hardware virtualization.

In most cases memory integrity is on by default in Windows 11.

This tutorial will show you how to turn on or off core isolation memory integrity in Windows 11.

Microsoft Defender Antivirus is an antivirus software that is included in Windows 11 and can help protect your device from viruses, malware, and other threats.

Enable or Disable Periodic Scanning in Microsoft Defender Antivirus in Windows 11

Limited periodic scanning is a special type of threat detection and remediation that can be enabled when you have installed another antivirus product on a Windows 10 or Windows 11 device.

This feature only uses a limited subset of the Microsoft Defender Antivirus capabilities to detect malware, and will not be able to detect most malware and potentially unwanted software. Also, management and reporting capabilities will be limited. Microsoft recommends enterprises choose their primary antivirus solution and use it exclusively.

By default, Microsoft Defender Antivirus will enable itself on a Windows 10 or a Windows 11 device if there is no other antivirus product installed, or if the other product is out-of-date, expired, or not working correctly.

If Microsoft Defender Antivirus is enabled, the usual options will appear to configure it on that device.

If another antivirus product is installed, registered, and working correctly, Microsoft Defender Antivirus will disable itself. The Windows Security app will change the Virus & threat protection section to show status about the AV product, and provide a link to the product’s configuration options.

Underneath any third party AV products, a new link will appear as Microsoft Defender Antivirus options. Clicking this link will expand to show the toggle that enables limited periodic scanning. Note that the limited periodic option is a toggle to enable or disable periodic scanning.

Sliding the switch to On will show the standard Microsoft Defender AV options underneath the third party AV product. The limited periodic scanning option will appear at the bottom of the page.

This tutorial will show you how to enable or disable Periodic Scanning in Microsoft Defender Antivirus when you have a 3rd party antivirus program installed in Windows 11.
