During long use of Microsoft products, I got a habit that to update Microsoft Office I need to download Service Pack for my MS Office version. But in MS Office 2013 I can easily press some buttons for updates.

It can be a good service so and a bad one. By default updates are enabled. It means that tey are downloaded through your Internet connection and installed automatically.

But if you use not unlimited Internet tariff (mobile network), you want to control traffic. In this case I advise you to disable automatic updates. It can be done in any MS Office application – Word, Excel, PowerPoint, etc. You need to click to tab "File" and choose option "Account" (Figure 1)

 

There you will see the button "Office Updates" and set the settings you need (Figure 2).
