Computer users who downloaded Windows 10 last week using Microsoft's Media Creation Tool installed the original July 29 edition of the latest OS. It was not the November upgrade after Microsoft stopped recently offering it as a disk image.

In its website page dedicated to download of Windows 10, Microsoft states, "These downloads cannot be used to update Windows 10 PCs to the November update (Version 1511)," reports CNET.

When Microsoft released the updates on Nov. 12, Gabriel Aul, Microsoft OS group's engineering general manager, suggested the use of the Media Creation Tool and disk images to get Version 1511. The number 1511 stands for the year and the month the upgrade, the first for Windows 10, was released. The original edition has the reference build 10240.


By using the two, Windows users would jump the queue and avoid the slow, staggered process that Microsoft uses to upgrade gadgets via Windows Update.

The disappearance of Version 1511 was observed by Windows users at the support discussion forum of Microsoft. When Winbeta reported the missing upgrade, Microsoft said on Saturday that the future installs would only be through Windows Update.

The new policy means users with devices that run on Windows 10 build 10250 must wait for Microsoft to offer the November upgrade in Windows Update which would be downloaded for each gadget. It goes against a previous pledge from Microsoft to offer disk images in .iso file format for every upgrade. The disk images allow advanced users another method to update their devices, making it unnecessary to upgrade multiple machines without the need to download the very large file to each system which consumes bandwidth and takes time.

Writing for ZDNET's The Ed Bott Report, Bott notes, "to add insult to those injuries, the sudden removal of the build 10586 ISO files means that the newly added capability to do a clean install using a Windows 7 or Windows 8 x product key is now unavailable to the general public unless they were fast enough to download and save an ISO file before the change."
