Windows 10 22H2 releases as a preview for testers

A new version of Windows 10 releases as a preview in the Release Preview Channel, and here's all you need to know.

Microsoft is now making available the first preview of Windows 10 22H2 in the Release Preview Channel of the Windows Insider Program. This minor update, described as KB5015878 (build 19045.1865), will install as a cumulative update without reinstallation.

Windows 10 build 19045.1865, according to the company, is available as an optional install for commercial customers and Insiders with computers enrolled in the Release Preview Channel that don’t meet the requirements to upgrade to Windows 11.

Also, since the focus now is on Windows 11 22H2 and on “Windows 12” arriving in 2024, this new version of Windows 10 doesn’t include any noticeable changes or new features. Instead, it’s a system update consisting of a couple of improvements for Focus assist and Windows Autopilot. And it addresses several problems already described on build 19044.1865 (preview) release notes.

Other than the small set of fixes and improvements, the new release bumps the version number from 21H2 to 22H2 and from build 19044.1865 to 19045.1865.
