Microsoft has rolled out the January 2026 non-security preview update for Windows 11 versions 25H2 and 24H2, giving users an early look at upcoming improvements, bug fixes, and quality enhancements ahead of next month’s Patch Tuesday.

As with all preview updates, this release focuses on stability, performance, and feature refinements rather than security fixes — making it especially useful for enthusiasts, IT admins, and early adopters.


What Is a Non-Security Preview Update?

Non-security preview updates are optional releases delivered near the end of each month. They allow Microsoft to:

  • Test bug fixes before wide rollout

  • Refine new or recently introduced features

  • Improve system reliability and performance

These changes are typically bundled into the following month’s mandatory update, unless issues are discovered.
