The update introduces a redesigned context menu that loads more quickly. While previous versions often felt cluttered, the new default menu shows eight items. App extensions now load only when a user opens their specific submenu. Users can customize which functions appear in the menu through Settings under Personalization.

Microsoft says Start, Search, right-click, Settings, and File Explorer are up to 20% faster than the January 2026 builds. On PCs with 8GB of RAM or less, Windows can keep up to 2GB more active data in RAM. Microsoft also says Widgets now save about 200MB of memory on these 8GB or lower systems. A new Cloud Rebuild option is also included, which uses a Windows image and fetches drivers through Windows Update.

Windows 11 24H2 Home and Pro reached the end of updates on October 13. 24H2 Enterprise and Education will receive security fixes until October 12, 2027, but they will not receive these new features. Windows 11 23H2 Enterprise and Education also reached its end of updates with this release.
