Microsoft has made its Office products ( Word, Excel, and PowerPoint ) available for download now.

If you are part of Windows 10 Technical Preview you can search for the programs in the new Windows Store beta today to test out the apps. If not, head over to the Microsoft Windows Insider Program website for information on how to join.

Word, Excel, PowerPoint, and OneNote will be pre-installed for free on Windows 10-based phones and small tablets; those with other gadgets can download the software from the Windows Store.

The new apps work best on touch screen devices. "These 'universal' Office apps are optimized for touch and mobile use and are a great way to take your work on the go, no keyboard or mouse required," Julia White, general manager for the Office product management team, wrote in a blog post.
