The Windows 10 April Update has begun seeping out from beneath the Redmond bathroom door. As an antidote to the excitement of the new, let us take a moment to mourn the passing of the old.

First on Microsoft's roll of honour was Groove Music Pass. The music service, which was loved by a niche of users, got a Spotify-shaped knife through the heart back in 2017. With the April 2018 Update, Microsoft has formalised the arrangement. The Groove app will now only play music on a PC or stream from OneDrive. If users want to source music elsewhere, well, there's an app for that.
