Thanks to new Edge 86 which adds DoH (even in GUI!), i removed Anti-Facebook list from AdGuard extension as my NextDNS config block it completely now :)
So now i only have "AdGuard Basis-Filter" list enabled in AdGuard to get rid of annoying YouTube ads for example.
If i wouldn't care about that, AdGuard were only useful for removing URL tracking parameter which is still use.

Good to know about DoH, Edge should really take you to a What's new page after it updates. Still not moved to adguard myself, got a mental block about it I guess lol.

@Andy Ful also use it this way.
Yes. Blocking Internet access to LOLBins usually does not produce issues (although some Windows telemetry performed via rundll32.exe and compattelrunner.exe can be blocked). Anyway, some applications can use (very rarely) LOLBins to call out/update, so it is reasonable from time to time to look at the Log for other blocked entries. (y)

What info did you need?
I am not sure. There can be several possible scenarios.
  1. There was an accidental time correlation between blocking lsass.exe by the firewall and Microsoft Store issue (less probable because you would recognize it). Did such a problem happen before?
  2. There is some application that is triggered when you try using Microsoft Store, and this application uses lsass.exe for something. If lsass.exe cannot make the outbound connection, then access to Microsoft Store is blocked.
  3. One of us uses a special system configuration. It would be helpful to see what setting can be the source of the different behavior of Microsoft Store on our computers.
You can make PM to not bloat this thread. Thank you. :)(y)
