On Windows Phone 7 you can do like this to get an anonymous unique id for the current user.
UserExtendedProperties.GetValue("ANID")
I have search for a while to find an equivalent for my current Windows 8 (WinRT), but I can't seem to find it. All the results I find, talks about how to get a Hardware/device specific ID, which IS supported, it's just not what I need.
Thanks in advance, Mads

Found out, thanks to xamlgeek an others, that it's not possible to get a Unique User Id in Windows 8 - at least for now.
So I have to fallback on Device Id, which is far from what I needed, but found this code snippet with works perfect (C#):

The answer is not good at all, because the user can upgrade his PC config (by pluging a bluetooth adapter or anything else). The good answer is to use the object :
Windows.Storage.ApplicationData.Current.RoamingSettings.Values["HighPriority"]
It's synchronized through the different installation of the apps on the cloud, more infos here : The HighPriority key is special because it's get automatically during the new installation of the app.

It's unwise to use GetPackageSpecificToken. This ID will change even if user just plug USB device into his PC/tab, or turn Wifi on/off. Actually it's a quite unstable thing, no idea why MSFT has ever made it.
I use LiveConnect instead (only Liveconnect user ID is needed and it's the same on all user devices). It much more reliable. See my post here: https://stackoverflow.com/a/22389679/1656824
