Microsoft's rollout of the Windows 10 October 2018 Update has been a rough road. On October 2, the company was so confident in it that it skipped over an entire ring of testing and brought it to the public. Four days later, it was removed from Windows Update servers due to files being deleted upon upgrading.
Later, issues were reported that have to do with extracting ZIP files. While the fix for that is in testing with Insiders, those that installed the update through production channels are still left without a fix.
But as reported by Brad Sams of Petri, this doesn't just affect consumers. It affects hardware manufacturers as well, and in a more significant way. For one thing, it's causing devices to ship with software that doesn't actually support the hardware in those devices.
Windows 10 version 1809 adds support for the Qualcomm Snapdragon 850 chipset and Intel's ninth-generation Core processors. Unfortunately, devices on the market using these chips, such as Samsung's Galaxy Book2 and Lenovo's Yoga C630, are still shipping with Windows 10 version 1803.
That means that these devices are using a version of the OS that's somewhat untested, and OEMs are counting on Microsoft to fix things. Presumably, when Windows 10 version 1809 does arrive, performance and stability on these devices will improve.
There's also an issue with marketing and promotional materials. Companies can't say a device is shipping with the Windows 10 October 2018 Update if it's shipping with the April 2018 Update.
Hopefully, Microsoft will have Windows 10 version 1809 ready soon. It's been over a month, and the main issues that have been reported have fixes that are in testing.
