The starter edition of Office 2010 includes Microsoft Word Starter Edition and Microsoft Excel starter edition, which do not have all the features of the regular Word and Excel. However, the starter edition will be enough for your day to day use of dealing with documents.
Why is Microsoft giving the Office 2010 starter edition free? Like we told you in the beginning this is not much of a free version and is instead an adware, so you can expect to see ads pop up while editing your documents or creating spreadsheets.
You can always try out Office Plus Professional 2010 till October 2010 by downloading it from the official download page.
