Still on Windows 10? The Word and Excel arriving this month is the last version that changes

Microsoft's own support documentation, updated in late July, puts a firm line under it: Microsoft 365 Apps on Windows 10 receive feature updates and Copilot support only up to Version 2608 - the release rolling out through August 2026. After that, those PCs stay on 2608 and get security updates only, until October 10, 2028.

The OneDrive desktop app follows a similar path. On Windows 10 22H2 it keeps updating to that same October 2028 date. On anything older than 22H2, it stops updating altogether, which is the cutoff we wrote about a few weeks back. There's a quieter change in the same document too: if you hit a problem that happens on Windows 10 but not on Windows 11, Microsoft support will simply ask you to move to Windows 11, and incidents on Windows 10 no longer include the option to log a bug.

None of this breaks anything next week. Word will still open your documents in 2027, and two more years of security patches for Office is genuinely more than Microsoft had to offer. What you're giving up is new features and, more practically, the ability to get a problem fixed rather than diagnosed. For plenty of people the hardware simply doesn't qualify for Windows 11, so the sensible plan is to know the date, keep your own copies of anything you'd hate to lose, and choose your moment instead of being pushed into one.

Tendvane's Health score gives you a plain read on where a machine stands - which Windows version it's running, whether updates are actually installing - so staying on Windows 10 stays a decision you're making rather than something that just happens to you.
