Ask Paul: May 25 (Premium)

It's the start of a long Memorial Day weekend, but here are some reader questions to get the holiday started.
Windows Hello and FIDO 2
StudBen asks:
I was curious as I know with 1803 Windows Hello was getting Fido 2.0 support and I realize it's in limited preview with Azure AD, and Fido 2.0 devices are still trickling out. Was curious if you heard of when Microsoft might have planned on adding support for this for consumer Microsoft Accounts, it would be nice to get a device like this to take the place of my password.
I've not heard anything in the past month. But it's safe to say that it's going to be while.

Microsoft announced this support only a month ago, noting that it would work with Azure Active Directory (AAD), Microsoft's cloud-based directory service for businesses. They never mentioned this support coming to Microsoft accounts. I assume that it will. But given the timing on AAD support---it's currently in a limited preview---I would not expect this to appear for consumers before the next Windows 10 release (1809) at the very earliest.
OneDrive and special folders
Dan1986ist asks:
With the changes coming to OneDrive such as the ability to move the location of known folders like Desktop and Documents into OneDrive, would this make it possible for a Microsoft Account to become a roaming profile and be accessible on mutiple systems? If so, would ordinary users benefit from this?
He's referring to this write-up if you're not familiar with the Known folder move feature that is coming this summer to OneDrive for Business.

I don't use OneDrive for Business, but if you look at how OneDrive works in Windows 10 today, you can already configure it to "roam" your Desktop, Documents, and Pictures folders---e.g. "sync them to OneDrive"---so that their contents are consistent across your PCs. And you can, of course, arbitrarily access/sync whatever content you store in OneDrive between PCs and other devices.

Windows 10 also syncs many of your settings with your Microsoft account (which is tied to OneDrive, too, of course). These two things---OneDrive and MSA settings sync---together constitute most of what a consumer would want from a roaming profile, as we understand it from the business world. So you might make the argument that this functionality is already there.

But what's missing?

True folder redirection, for one: This is what Known folder move appears to do in OneDrive for Business, and I noted at the time that such a feature would be very useful (for example, for those with multiple drives). Also, full special folder support: OneDrive doesn't let you easily move your Music or Video folders across PCs.

The biggest missing feature today, however, is what I'll call "full settings sync": Windows 10 today syncs many, but not all, settings between PCs. I feel like this could be more complete.

Anyway, as noted, I feel like the current implementation will satisfy most consumer's needs today. The ability to just open...
