If you have been following twitter at all today, you'll find plenty of details about Service Pack 1 for Office 2013 and SharePoint 2013. I applied the update to my Surface 2, Surface RT, laptop running Office Professional Plus 2013 and Microsoft Office 365 ProPlus. With all of my devices, everything is working so far. You can find the update by checking Widows Update on your machine and then selecting it under the optional updates. There are also a number of direct download links as well.
One thing I noted on my laptop running Office 365 ProPlus (the Click-to-run install from my Office 365 subscription) is that it didn't update automatically. I was stuck on version 15.0.4551.1512. Thanks to @WesMacDonald for tipping me off that you can get the update to come down by Disable Updates and Re-enabling updates. You can find the option under the Update Options button under Office Account.
After, you make the change just sit back and relax a bit as the change will show up before you know it. Once it does, you may get a message like this asking you to close down Office programs.
Once you do, the update will start and you will see a notification in your taskbar.
It doesn't take long to finish. Not more than a few minutes.
When it's all said and done, your version number will now show as 15.0.4569.1507.
You will also notice that SkyDrive Pro is no more and you will have a link for OneDrive for Business.
A look at OneDrive for Business
In reality, you won't notice many changes between OneDrive for Business and the old SkyDrive Pro. The functionality looks the same but you will just see OneDrive in all of the menus. Here is the synchronization screen.
Then, here is the screen when the synchronization is in progress.
The final synchronization screen.
You'll even see OneDrive for Business listed in the context menu.
Do all of us a favor and never refer to the SharePoint file synchronization offering as just "OneDrive". Don't be lazy, always say "OneDrive for Business". This will lead to people confusing it with the consumer OneDrive offering. I don't know how many executives I had to explain the difference between SkyDrive and SkyDrie Pro to. Help us all out and always refer to the product by it's complete name. :)
