If you're using Office365 it tends to auto update and happily forget you don't want to have OneDrive on your machine, so it reinstalls it.

It kinda annoying because OneDrive is a piece of shit in general, but saving directly to SharePoint from Office apps is useful. As with many Microsoft services, OneDrive is just SharePoint in disguise. But I really would like the SharePoint bit without the OneDrive bit.

I also don't like the whole cloud first thing, pushing everything to Microsoft services. But I understand why they did it, for regular dumb users storing shit on a cloud service is probably better than on the computer. I've had multiple co-workers send me Word docs with a list of linked documents (why is this a feature and why do people use it?), which all linked to the local Documents folder. They said they checked all the links before mailing the Word docs, so it must be me who is mistaken.
