So you installed Microsoft Office 2013 and now you’ve got a new context menu item: “SkyDrive Pro”, when you right-click a file, that is gray out, right? Although, this is not a big issue, it is a little annoying to have the option listed, when you don’t actually have the feature.
Honestly, this is a pointless option for regular users to have, did you know that SkyDrive Pro and SkyDrive are different products? The SkyDrive Pro option will only work for businesses with SharePoint and not with the actual cloud storage service you’ll get when creating an Outlook.com account. Microsoft may have its reason to append the option there, but it should have included an option to remove it too.
Now if you want to remove the SkyDrive Pro option from the context menu list follow the steps below:
Instructions
1. Use the 
+ R keyboard shortcut to open the Run command and type regedit.
2. Browse the following registry key.
HKEY_CLASSES_ROOTAllFilesystemObjectsshell
Quick Tip: The HKEY_CLASSES_ROOT has a long list, so press the letter “A” to get closer to the AllFilesystemObjects.
3. Next expand shell and delete the SPES.ContextMenu folder which has several keys.
That’s pretty much all you have to do. Now go to the desktop, or from inside a folder, right-click a file and the “SkyDrive Pro” option should be removed from the menu.
