Microsoft has launched a new Windows beta for its latest operating system.

The beta, named ‘Worm’, is available to download today on Windows 10, Windows 8.1, Windows 7 and Windows Vista and is free for anyone to download.

The Redmond-based software giant said it was “proud” to be bringing the new Windows feature to its customers.

“Worm is a free update that improves the overall user experience, including security, stability and performance, to bring you the most secure and reliable Windows experience possible,” a Microsoft spokesperson said in a statement.

“We’re excited to bring Worm to more people in the coming months.”

Windows 10 will be rolled out to customers in Australia and New Zealand on Tuesday, with a rollout planned to go further in the US, UK and Ireland later this month.
