More and more Group Policies for OneDrive and for Windows 10 were established to give administrators control over devices, storage, and behavior. This session describes the user behavior to sync many files from different libraries for collaboration, not only from their own tenant, but also from other tenants through B2B sync, and give the administrators full control via Group Policies. These GPOs not only for OneDrive, but also for the different devices, control Windows 10 through OneDrive Files on Demand and Storage Sense, and also help user behavior of deleting files by mistake.
Currently, "Download video" link leads to xml (and not mp4 recording) which tells that "Server failed to authenticate the request". No problem - simply grab the manifest from CDN manually (I've found the link via Inspect feature in Chrome - just click on play, go to Network tab and look for manifest): https://amsmedius.studios.ms/53cd875a-37d8-4c3d-9ca8-37df2a75b85d/THR2345_1280x720_3400.ism/manifest...), then find the best quality video (1_V_video_1), audio track (5_A_audio_eng_1), glue those two together and there you go. Youtube-dl can be used to automate this. It's unlikely that someone from MSFT will ever see this anyway, so I'll just leave it here for anyone who wants to simply download the stream and not wait when someone else will fix things, if ever. Ignite sessions this year are great source of quality information, so if you encounter that some of those sessions are not downloadable, but you can play those in browser - well, try to download them grabbing those dash segments with some youtube-dl. And if player has some issues - then look for manifest anyway and try to download.
