Hello all. Thank you for your patience. I'm the Product Manager for Smartscreen in Microsoft Edge and I want to provide a quick update. We've developed a fix to address this issue, and we're in the final stages of testing and validation before shipping to all customers. The fix will be available starting edge v104 and on later releases.

The NewSmartScreenLibrary policy is still available and will remain available until we're confident the issue has been resolved. The plan as of now is to deprecate it in v107. More details to come later on. https://docs.microsoft.com/en-us/deployedge/microsoft-edge-policies#newsmartscreenlibraryenabled

Today I updated my environment to 105.0.1343.27 and unfortunately it doesn't work anymore.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\NewSmartScreenLibraryEnabled = 1 / SmartScreen is not working.
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\NewSmartScreenLibraryEnabled = 0 / SmartScreen works

However, a downgrade to 104.0.1293.70 worked fine:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\NewSmartScreenLibraryEnabled = 1 / SmartScreen works.
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\NewSmartScreenLibraryEnabled = 0 / SmartScreen works.

Can anyone confirm this?

    Hello Kelly_Y,
    
    I did some further testing and found a difference between Windows 10 (21H1 in my case) and Server 2016:
    
    Windows 10 21H1
    Edge 105.0.1343.27
    NewSmartScreenLibraryEnabled = 0 / working
    NewSmartScreenLibraryEnabled = 1 / working
    Edge 104.0.1293.78
    NewSmartScreenLibraryEnabled = 0 / working
    NewSmartScreenLibraryEnabled = 1 / working
    Edge 104.0.1293.70
    NewSmartScreenLibraryEnabled = 0 / working
    NewSmartScreenLibraryEnabled = 1 / working
    Edge 103.0.1264.49
    NewSmartScreenLibraryEnabled = 0 / working
    NewSmartScreenLibraryEnabled = 1 / NOT working
    =======================================
    Windows Server 2016
    Edge 105.0.1343.27
    NewSmartScreenLibraryEnabled = 0 / working
    NewSmartScreenLibraryEnabled = 1 / NOT working
    Edge 104.0.1293.78
    NewSmartScreenLibraryEnabled = 0 / working
    NewSmartScreenLibraryEnabled = 1 / NOT working
    Edge 104.0.1293.70
    NewSmartScreenLibraryEnabled = 0 / working
    NewSmartScreenLibraryEnabled = 1 / working
    Edge 103.0.1264.49
    NewSmartScreenLibraryEnabled = 0 / working
    NewSmartScreenLibraryEnabled = 1 / NOT working
    
    May someone else can confirm?
    
    Regards.
