Microsoft is still trying to figure out Windows 10 support

Microsoft is still trying to figure out Windows 10 supportMicrosoft has backed off a possible confrontation with customers who had been told their two-to-four-year-old PCs were unfit for Windows 10, a sign, said one analyst, that the company remains unsure of its support strategy for the OS.

Earlier this year, Microsoft blocked a class of low-end personal computers - those equipped with Intel's Atom system-on-a-chip (SoC) processors, dubbed "Clover Trail," part of the "Cloverview" architecture - from receiving the Windows 10 Creators Update. Also known as 1703 in Microsoft's year/month parlance, Creators was the first feature upgrade of the year, and the third since the operating system's launch.

Those Clover Trail-powered devices were made and sold between 2012 and 2015 - the latter the same year Windows 10 debuted - and many if not most were eligible for the free upgrade to 10 that Microsoft offered. But the company balked at serving those machines 1703, telling users in April that because Intel dropped support for four models of the Clover Trail SoC, the PCs "may be incapable of moving to the Windows 10 Creators Update without a potential performance impact."

(Intel calls this state, "End of interactive support (EOIS), which means it no longer offers phone-, chat- or email-based support. Microsoft cited a lack of "necessary drive support" on Intel's part as well, hinting that the issue was largely due to the SoCs' integrated graphics.)

"They're still vague about the constraints to Windows 10 support," said Stephen Kleynhans, an analyst with Gartner. "They're still trying to figure out [support] themselves."

The background: A built-in support contradiction

Some background is required to put Microsoft's decision, or indecision, into context.

Windows 10 suffers from a support contradiction. On the one hand, Microsoft has said that the OS will be the last version of Windows, ever, implying that it will be updated and maintained - "serviced" in the company's vernacular - for all time.

Yet Microsoft has also set the usual 10-year limit on Windows 10 support, setting the end of its "product lifecycle" as Oct. 14, 2025, for almost all versions of the operating system. (The exception: Windows 10 LTSB, for "Long-term Servicing Branch," a change-free SKU available only to enterprise customers, which currently has an end-of-support date of Oct. 13, 2026, or 10 years after the appearance of the last approved LTSB build, mid-2016's Anniversary Update.)

But Microsoft has stuck a different kind of monkey wrench into the works, one that raised questions when it was announced two years ago and was the cause of the recent consternation over Clover Trail. According to company statements of the past, Windows 10 was to be "supported for the life of the device," a timespan it never defined. In its own documentation, Microsoft gets more specific: "A device may not be able to receive updates if the device hardware is incompatible, lacking current drivers, or otherwise outside of the Original Equipment Manufacturer's ('OEM') support period," that documentation reads.

This was the out Microsoft gave itself when it explained why it denied the Clover Trail SoC-powered machines the right to upgrade to Creators Update, aka 1703. "They require additional hardware support to provide the best possible experience when updating to the latest Windows 10 feature update, the Windows 10 Creators Update," Microsoft said. "However, these systems are no longer supported by Intel, and without the necessary driver support, they may be incapable of moving to the Windows 10 Creators Update without a potential performance impact."

Later, Microsoft threw more fuel on the fire when it nailed down the support timetable for each feature upgrade. Its original plan - 12 months of support - was clearly too short, relying on a three-times-a-year release cadence. So, Microsoft extended the support lifespan to 18 months, that period defined by a twice-a-year release tempo. According to Microsoft, once the 18 months was up, a Windows 10 device would no longer receive security updates and other bug fixes. The only way to continue receiving those updates and fixes was to upgrade to a new feature upgrade.

And that was a problem for Clover Trail. The systems would be stuck on the Anniversary Update, or 1607, which by Microsoft's schedule, would drop off support in March 2018.
