Microsoft doesn't plan on making the same mistake twice: the company has made a public pledge that all of Nokia's Lumia Windows Phone 8 devices will be upgraded to the mobile version of Windows 10 when it's released. Responding to a customer's question on the topic, Microsoft tweeted, "We plan to upgrade all Windows Phone 8 devices to Windows 10 in the future." Microsoft's next big operating system remains in early development, so the company obviously isn't revealing details as to when that update will arrive.

Still, the direct confirmation should allow Lumia owners to breathe a sigh of relief and know that history won't repeat itself. Microsoft enraged its small but loyal base of Windows Phone 7 users when it revealed existing devices wouldn't make the jump to Windows Phone 8 in 2012. That was mostly due to a significant change in the software's kernel, but the technical explanation did little to heal the wound. The underpinnings between Windows Phone 8 and Windows 10 aren't so drastically different, so another cutoff wasn't expected. But a promise that every last Lumia running Windows Phone 8 will get Microsoft's latest software is still good to hear.
