Microsoft announced: Win10 Mobile Insider preview expires on October 1

Microsoft has completed the development of the core functions of Win10 Mobile. The main work at this stage is to further improve the system, remove bugs, and have plans to complete system development in September. According to the Microsoft Insider website page description, Microsoft does have plans to complete system development in September and push a new version of the upgrade to Insider users.

According to the Microsoft Windows Insider web page, the operating system will prompt you to upgrade to a higher version of the Insider preview from September 15th. The preview version will expire on October 1. This warning has appeared since at least since March (not noticed), so we don't think this update will work for any particular Insider preview.

The following paragraph is described on the Insider website "System Requirements" page:

“Insider Preview will expire on October 1, 2015, if You are running the Insider Preview and we will send you a notification starting on September 15, 2015, reminding you that you need to upgrade your phone to a later version. ”

Foreign media said that this text has not changed since at least since March, so it is not like a description for a particular preview. This means that Insider users will receive a non-Insider preview upgrade push after September 15. And the inderer user will have two weeks to download the upgrade. After the time is exceeded, you may lose your eligibility to continue upgrading.

Of course, it is not certain that the official version upgrade will be received after September 15th, but according to the description is the version of the current version of the Insider preview.
