Microsoft will offer free upgrades to Windows 10 for the first year after the operating system launches, Microsoft’s executive vice president of Operating Systems Terry Myerson said on 21 January 2015.
Addressing journalists at a press event held at Microsoft’s headquarters in Redmond, Washington, Myerson said the free upgrade will be available to Windows 7, Windows 8.1, and Windows Phone 8.1 users.
Once a device is upgraded to Windows 10, Microsoft will keep it current for the “supported lifetime for the device”.
“You can think of Windows as one of the largest Internet services on the planet,” said Myerson.
Just like all other online services, the question “what version are you running” will cease to make sense, he added.
“But what about enterprise?” Myerson asked.
“We will continue to support the way Windows works today, with long term branches and long term support,” he said.
Windows 10 is currently in preview via the Windows Insider Programme. Microsoft has previously said it will be available by “fall 2015” (September – December 2015).
