Need to reinstall Windows 10 from scratch? Microsoft says: “wait till RTM”

This week, Microsoft has reportedly deactivated all temporary license keys issued with all Windows 10 Preview, according to a support post published on July 16th. The timing couldn’t be more perfect as Microsoft moved ahead with the mass deactivation, as the official RTM version of Windows 10 is now merely 10 days away.

“...We hope Insiders will continue to test Build 10240, which is only intended to be installed as an upgrade from a previously-activated version of Windows 10 Insider Preview – we do not support clean installs of Windows 10240. Windows 10 is intended to be installed on Genuine Windows devices, whether devices in the Windows Insider Program or those taking advantage of the free upgrade offer...” wrote Microsoft Insiders forum moderator Rohit Chettri.

Windows insiders who have already activated their installations, and are actively using Windows 10, have nothing to worry about, as they will simply transition into the official commercial version of Windows 10 on their devices.

The only caveat is with anyone needing to reinstall Windows 10 from scratch, prior to July 29th. Microsoft has make it clear that preview builds, including 10240, will no longer accept new activations with keys provided by the Insider program.

On the upside, this means that Windows 10 is definitely ready for prime time, and Insiders will be the first to receive the brand new operating system on their devices.
