Windows 10 will be an opportunity to discover universal Office applications in order to offer the same Office experience (Word, Excel, PowerPoint, OneNote and Outlook) on smartphones, tablets and PCs. They have been optimized for touch as with Excel to create and modify spreadsheets.
These new Office applications will be pre-installed free of charge on small smartphones and tablets (less than 8 inches) equipped with Windows 10. For other devices, they will be available for download from the Windows Store.
At this point, we don't know if they will be free to download or if an Office 365 subscription will be necessary to access advanced editing and collaboration features as is currently the case on iPad and Android tablet.
But beyond the universal applications, there will also be an Office 2016 office suite whose launch is expected in the second half of 2015. There had already been some leaks on this subject.
For the moment, Microsoft does not say much more about Office 2016 and promises to reveal more in the coming months. " This suite will remain the most complete Office experience you are familiar with, best suited for a PC with a keyboard and mouse. "
In the meantime, screenshots of the Office apps for Windows 10 (universal apps) are being released:
