Allow download restrictions

Configures the type of downloads that Microsoft Edge completely blocks, without letting users override the security decision.

Set 'BlockDangerousDownloads' to allow all downloads except for those that carry Microsoft Defender SmartScreen warnings.

Set 'BlockPotentiallyDangerousDownloads' to allow all downloads except for those that carry Microsoft Defender SmartScreen warnings of potentially dangerous or unwanted downloads.

Set 'BlockAllDownloads' to block all downloads.

If you don't configure this policy or set the 'DefaultDownloadSecurity' option, the downloads go through the usual security restrictions based on Microsoft Defender SmartScreen analysis results.

Note that these restrictions apply to downloads from web page content, as well as the 'download link...' context menu option. These restrictions don't apply to saving or downloading the currently displayed page, nor do they apply to the Save as PDF option from the printing options.

See https://go.microsoft.com/fwlink/?linkid=2094934 for more info on Microsoft Defender SmartScreen.
