It has been a long time coming but Windows 10 is finally making its way to billions of devices the world over. In an unprecedented move for the tech giant, the new and improved operating system is available as a free upgrade for anyone who's currently on Windows 7 or Windows 8.1. Consumers buying Microsoft-compatible computers and tablets from today will also find the new version of Windows pre-installed on their device.

We'll say it straight up — given the underwhelming facelift of Windows 8, we weren't holding our breath for its successor. But thankfully, Windows 10 has a lot more going for it, and we've rounded up three stand-out features you can look forward to:

1. Microsoft Edge

Microsoft's answer to Google's Chrome and Apple's Safari lets you do something the other web browsers can't — scribble or type notes directly onto webpages, which you can then flick to your friends via email or social networks. The ability to peruse articles in the new distraction-free reading mode is also a welcome feature for those who get carried away by too much toggling.

2. Cortana

Does the world need another Siri? Apparently so. Meet Cortana, your personal digital assistant on Windows 10. It drops timely reminders to help you keep track of meetings and such important dates as birthdays and anniversaries. As with Siri, you can type or voice your queries to get it cracking. While Apple is rumoured to be working on a version of Siri for OS X, props goes to Microsoft for beating them at their own game.

3. Windows Hello

Bid multiple password chains goodbye as you can now sign into your device with your face or fingers. The biometric authentication feature is used in conjunction with specialised hardware like fingerprint readers, but if you already have the Intel Real Sense 3D camera installed, it's a breeze to activate the facial recognition option.
