Device Compliance - Windows

Device compliance is one of the current security requirements for conditional access at the University of Windsor. 

For your computer running Windows OS to be deemed as compliant, it must meet all these requirements: 

  • Windows 10 version must be 22H2 or 21H2 with latest security patches installed (more details).


  • Windows 11 version must be 23H2 or 22H2 with latest security patches installed (more details).


  • Windows Security real-time protection must be enabled (more details).
  • Microsoft Defender anti-malware must be enabled and up-to-date (more details).
  • Microsoft Defender anti-spyware must be enabled (more details).
  • Windows Firewall must be enabled (more details).
  • Device must used at least once every 30 days (more details).

To check if your device is compliant or update its compliance status, launch the Company Portal app installed on your university device or go to on any device and:

  • Click on the menu (three lines) next to "University of Windsor" to open the navigation bar (web version of Company Portal only)

  • Click Devices on the navigation bar on the left
  • Click on the device of interest
  • Click Check Access

This will force a check-in with the Intune cloud service and refresh its device compliance policies and status.


Windows Version and Updates

For the device to be deemed as compliant:

  • Monthly Windows quality updates (security patches) generally have to be installed within four weeks from the day they were released by Microsoft.
  • Semi-annual feature updates have to be installed within two months from the day they were released by Microsoft.

To check version/build of Windows 10/11 on your computer:

  1. Click the Start menu and type winver then Enter
  2. Make a note of the second line that should look like this:
    • On Windows 11: Version 23H2 (OS Build 22631.3296​​​​) or Version 22H2 (OS Build 22621.3296) - this includes Mar 12 security update
      NOTE: It's OK if your last number is higher than 3296​​​​​​​
    • On Windows 10: Version 21H2 (OS Build 19044.4170​​​​​​​) or Version 21H2 (OS Build 19045.4170​​​​​​​) - these includes Mar 12 13 security update
      NOTE: It's OK if your last number is higher than 4170​​​​​​​

To update your Windows to the latest supported version, go to Windows settings:

  1. Click Start menu (Windows logo)
  2. Click the gear icon (Windows Settings)
  3. Click Update & Security
  4. Click Check for Updates
  5. Install missing updates
  6. Reboot your computer

If Windows Update feature tells you that there are no updates available for your computer even though your version/build is not at the level listed required, you can update to the latest version/build of Windows 10/11 following these steps:

  1. Launch a web browser and navigate to this site:
  2. Click Update Now
  3. Your browser will attempt to download Windows Update Assistant app. Open/run this file, or save it in your Downloads folder and then open it once it is downloaded.
  4. When asked Do you want to allow this app to make changes to your device? Click Yes.
  5. Follow the instructions on the screen.

Virus and Threat Protection

Windows 10 includes Windows Security module, which provides virus, malware and spyware protection settings.

University (Corporate) Devices

Cortex XDR must be installed on every university device. When installed, it takes over the real-time protection function from Microsoft Defender Antivirus.

Personal Devices

On personal devices, Microsoft Defender Antivirus provides adequate threat protection on your personal computer. Your device will be actively protected from the moment you start Windows 10/11, as long as the Windows Security features listed below are enabled and functioning properly. Windows Security continually scans for malware, viruses, and security threats. In addition to this real-time protection, updates are downloaded automatically to help keep your device safe and protected.Starting with Windows 10 version 2004, Windows Defender Antivirus (which is one of the components of Windows Security) has been renamed to Microsoft Defender Antivirus.

Real-Time Protection

In Windows 10/11, you can turn off Microsoft Defender Antivirus real-time protection, but it will only be temporary unless disabled. Windows will automatically turn real-time protection back on. Always-on protection consists of real-time protection, behaviour monitoring, and heuristics to identify malware based on known suspicious and malicious activities. These activities include events, such as processes making unusual changes to existing files, modifying or creating automatic startup registry keys and startup locations (also known as auto-start extensibility points, or ASEPs), and other changes to the file system or file structure. To check your real-time protection settings:

  1. Click Start menu, then Settings (gear icon)
  2. Click Update & Security
  3. Click Windows Security
  4. Click Virus & threat protection


NOTE: When you install a third party antivirus software, which is optional and at your discretion, it will take over the real-time protection function from Microsoft Defender Antivirus. This will not affect device compliance as long as the third party antivirus will be updated on a regular basis.


Microsoft Defender Anti-malware and Anti-spyware

The Anti-malware Service Executable process is Microsoft Defender’s background service, which always runs in the background. It’s responsible for checking files for malware when you access them, performing background system scans to check for dangerous software, installing antivirus definition updates, and anything else a security application like Microsoft Defender needs to do.

Windows Firewall

On your work computer, Microsoft Defender Firewall must be on to protect your computer from unauthorized access. To check if your computer's Microsoft Defender Firewall is on or off:

  1. Click Start menu then Settings (gear icon)
  2. Click Update & Security
  3. Click Windows Security
  4. Click Firewall & network protection. You should see Firewall is on message next to Domain network, Private network, and Public network.

  5. If any of the three networks display a message that the Firewall is off, click Turn on to turn it back on or click Restore settings to restore firewall settings to the recommended values.

For more information, please see Turn Microsoft Defender Firewall on or off

Device must be used at least once every 30 days

All devices administered must be used and signed into at least once every 30 days to stay compliant.

Devices that did not check in with Intune for more than 180 days, are automatically removed from Intune and then will be wiped and need to be re-enrolled. To prevent data loss, please always store all your files on your OneDrive or inside one of your teams.
