The Microsoft corporation has been giving away free access to their Windows Office 365 product for one month, they are doing this in two type of versions. The first version has been made for households and private users, it allows them to use all the Windows Office applications in the cloud, so this means that everything is online. The second one is the Windows Office 365 personal edition, this edition has been made for private users which simply want a single account. The first edition costs 8 dollar (7.99) after the first month and the second edition costs 6 (5.99) dollar after the first 1-month free trail.
But did you know that there is an awesome, free and secure edition which can be downloaded by everyone?! It is provided to Windows and Linux users and it does exactly the same like the Windows Office series.
I am talking about Apache OpenOffice. The Apache OpenOffice projects holds various applications which do exactly the same like the Windows paid licenses. The Apache OpenOffice products provides the Writer, Calc, Impress, Draw, Base and Math applications for free.
The writer application can be seen as the Office Word application and the Calc application can be seen as the Excel Windows application.
The OpenOffice product is free to use and it is very user friendly. It costs nothing and it is updated by the community and the founders of Apache OpenOffice which guarantees that people are always taking a look at the security status of OpenOffice.
I strongly recommend you to skip the Microsoft license and simply try the OpenOffice product which is free.
