Microsoft a annoncé un nouveau Centre de sécurité Windows Defender à partir de Windows 10 v1703 et cela permet de basculer les paramètres de sécurité pour nos PC. Par défaut, Windows Defender est configuré dans un mode de protection faible, car cela facilitera notre vie en imposant moins de restrictions, mais les administrateurs informatiques peuvent activer Cloup Protection et modifier ces paramètres de stratégie de groupe - Configurer le bloc à la première vue, Configurer la substitution de paramètre local pour Reporting, et rejoignez Microsoft MAPS (Microsoft Advanced Protection Service) ou SpyNet, pour définir la protection Antivirus de Windows Defender aux niveaux les plus élevés.

If you are a user of Windows 10 Home, then you can use the Windows Registry and tweak some settings. To do this, type regedit.exe in Start Search and hit Enter to open the Registry Editor. Now navigate to the following key:
HKEY_LOCAL_Machine\Software\Policies\Microsoft\Windows Defender
In the left side, right-click on Windows Defender, select New > Key and name the key Spynet. Right click on Spynet and again select New > Dword (32-bit) and name it SpynetReporting. Set its value to 2 to set it at Advanced level.
Now, again right-click on the Windows Defender key which appears in the left side and select New > Key. This time name the key as MpEngine. Next right-click on the MpEngine key and select New > Dword (32-bit) value. Name the key as MpCloudBlockLevel and give it a value of 2 to set it at High block level.
