Microsoft has announced that its existing Lumia handsets running Windows 8 will update to Windows 10 when it becomes available. It made the pledge on its official Twitter account, in response to a customer question, tweeting, “We plan to upgrade all Windows Phone 8 devices to Windows 10 in the future.”
Though not exactly a press announcement, such a public declaration on an official social media account suggests the statement can be taken as concrete. Two years ago, Microsoft displeased Lumia users when they revealed that Windows Phone 7 devices would not be updated to Windows 8 due to a kernel problem. The company seems to have made plans to avoid undermining customer satisfaction a second time.
No release date for Windows 10 has been confirmed, but it’s expected to be available in 2015.
