I've done some quick tests. The Canary channel installs Edge in the LocalAppData folder, not what you want. So I switched to the Beta channel, this installs Edge in the Program Files folder. After that I ran the Edge browser through the Profiler and done some quick and dirty 'optimization' to create this Config File: === [IncludeRegistryTrees] HKCU\Software\Microsoft\Edge HKCU\Software\Microsoft\Edge Beta HKCU\Software\Microsoft\Edge SxS HKCU\Software\Microsoft\EdgeUpdate HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings [IncludeFolderTrees] <LocalAppData>\Microsoft\Edge Beta <LocalAppData>\MicrosoftEdge === As you can see, settings are stored in a folder called 'Edge Beta', probably because this new Chromium Edge gets installed next to the existing Edge. So we need to wait for the final release to see how this would behave. With the config file content above I was able to roam the start page, theme, favorites, saved passwords, etc. I could not detect any broken or missing settings. The .ZIP file was 35MB in size, but we might be able to optimize this by excluding stuff we don't need. Focus right now for me was to see if we could capture all settings. Please give this a try and let me know your results.
