Windows 10 version 1703 and later provides the latest antivirus protection with Windows Defender Security Center, which contains Windows Defender Antivirus. When you start up Windows 10 for the first time, Windows Defender Antivirus is on and actively helping to protect your device by scanning for malware (malicious software), viruses, and security threats.
Windows Defender Antivirus uses real-time protection to scan your downloads and the programs you run on your device. Also, Windows Update downloads updates for Windows Defender Antivirus automatically to help keep your device safe and protect it from threats.
Starting with Windows 10 version 1709, the Device Performance & Health section can be hidden from users of the PC. This can be useful if you don’t want them to see or have access to this section.
If you choose to hide the Device Performance & Health section, it will no longer appear on the home page of the Windows Defender Security Center app, and its icon will not be shown on the navigation bar on the side of the app.
This tutorial will show you how to hide or show the Device performance and health section in the Windows Defender Security Center app for all users in Windows 10.
