Smartscreen not working / delay in downloading files
bhkumar007 thanks for the suggestions, never knew these items were available. I'm not sure what i'm looking at though; what does 0, 1, 2 etc mean with these histogram results (these results are only when clicking a few of the demo items on demo.smartscreen.msft.net).

Microsoftmarceldk 2 indicates the internal code error in SmartScreen (looks like it is related to environment you are using). Can you run edge://tracing with SmartScreen category? If there is any error message in there, that will help pinpoint the issue.
bhkumar007 I've had to capture from start-up (used the info @ https://www.chromium.org/developers/how-tos/trace-event-profiling-tool/recording-tracing-runs) to catch these events.
C:\Program Files (x86)\Microsoft\Edge\Application>msedge.exe demo.smartscreen.msft.net --trace-startup --trace-startup-file=H:\trace_startup.json --trace-startup-duration=5

Edit, looks like I skipped over some events, most of them are the same as above but this one is different (and a little later on in the trace):

marceldk Thanks for sharing the details. It does give an idea on where the issue lies. Can you share the details on OS version/architecture/sku you are using? I don't see the issue on a regular Win7 machine
bhkumar007 this is Windows 7 Enterprise 6.1.7601 SP1, x64. Running on an Intel Xeon CPU E5-2680 v2 with 5GB's of RAM with Dutch language settings.
I've noticed that when I install the Beta build (or Dev) next to the stable 81.x version, SmartScreen does work in that browser. But we've reinstalled this 81.x a few times now but no changes in behaviour. The difference being that the 81.x is installed during our automatic process with ConfigMgr's Task Sequences to build the new VDI images and the Beta/Dev build is installed manually in this case.
