On one of my Windows 8.1 machine, the SkyDrive is updated to OneDrive - just a name change, nothing else that I notice. But on another one, it's not updated. I tried to check the updates, installed all latest ones, still don't see it updated. Any tricks on how to do this? Also I notice that the Windows Store app of SkyDrive still has the old name, weird.
Nothing is wrong. As long as you are signed in with a Microsoft account, you are fine.
Microsoft is just a little slow at changing its names so quickly; the same is happening to me.
Eventually, at some point, it will be renamed. They're probably doing Windows 7 first because it is more popular. If you are running Windows XP, you won't receive the update to "Onedrive".
