AmiMoJo writes: When Microsoft released Windows 10 version 1511 earlier this month, the company also updated the installer files it delivers via a free, downloadable media creation tool (MCT). That upgrade option worked as advertised for more than a week. This weekend, however, the new files have been pulled and the media creation tool available for download from that page instead installs the July 2015 (build 10240) release. A Microsoft spokesperson confirmed they wish people install the older version and get the 1551 update via Windows Update. The more recent release is still available via an unpublished link (EXE download).
