In Windows 10 Microsoft's OneDrive service will now be in integrated part of the OS instead of a separate app or program



From Supersite for Windows:

Microsoft has talked about this openly as it allows them to update services much quicker since it is just on the app level vice the entire OS. We have seen the proof of this in many areas including apps like News, Sports, Finance, Music, Video and even OneDrive. In some cases updates are released weekly which is something we would have never seen in the past.

Well it looks like there is at least one app and its related service that will be making its way back into the Windows 10 operating system and away from being a separate app.

  OneDrive will be integrated with Windows 10
