Software giant Microsoft has made its preview for the phone version of Windows 10 available.

However, you’ll have to first install the Windows Insider app and sign up for the Insider Program to get a taste of the new features available with this build.

Some of the new features include:

  • Full size wallpapers for your Start screen
  • An expanded Quick Actions view in the Action center; you can now see up to three rows of actions (vs one row of four previously)
  • Enhanced speech-to-text which you can now use in any data field. Words appear as you say them and the technology is smart enough to differentiate between “two” and “too
  • A more powerful Photos app that will aggregate local photos with those stored on OneDrive

This is the first Windows 10 preview (desktop included) to show off the upcoming Project Spartan browser engine. The technology is currently hosted in Internet Explorer, but expect a new browser to replace IE in future builds.

You will need one of six compatible Windows Phone devices: the Lumia 630, 635, 636, 638, 730 or 830. to be able to test.
