Edge installed via SCCM behaves differently than Edge installed C2R

I did some more testing, and I think I have a better handle of what is going on. 

1. It looks like the ExternalProtocolDialogShowAlwaysOpenCheckbox policy no longer works at all in Dev 82.0.432.3 and Canary 82.0.439.0 (which I had installed C2R). I installed the latest Edge Dev MSI on a Windows 10 Home machine not joined to our domain, configured this policy in the registry, and it also will not show the checkbox either. It still works in Beta 81.0.416.16. I assumed this was caused somehow by the change in deployment method, but it turns out I just hadn't tested it in the most recent Dev version. I might create a separate thread about this bug. 

2. The failure to import IE favorites seems to be hit or miss. I am used to it failing on Edge 80/81, but 82 had been working pretty reliably after they put in the fix in this thread:

It seems like it is mostly happening on machines on which a previous version of Edge Chromium had been installed. I imaged a new machine and the deployment and favorites import worked fine on that.
