Move over iPhone Duo announcement, the real news is here. Windows 11 will soon feature a few more emojis. Microsoft recently shipped Windows 11 Builds 26100.9539 and 26200.9539 to Insiders in the Release Preview Channel. Among other changes, the update adds support for Emoji 17.0.
Since these are Release Preview builds, many of the included changes have already been seen during earlier Insider testing.
Several changes have been made to File Explorer that should make for a smoother experience. Home within File Explorer now preserves the state of sections, so the next time you open the app things will be expanded or collapsed as before. Thumbnail previews for cloud files should appear more consistently as well following this update.

Emoji lovers will be happy to hear that Emoji 17.0 support comes with this build of Windows 11. Emoji 17.0 adds the distorted face, fight cloud, and hairy creature (Bigfoot) emojis.
Microsoft continues on its recent push to create more widgets. These Insider builds add a Tips widget that provides guidance about Windows features. Microsoft recently announced a battery widget that’s in the works as well.
Another welcome change is the update to remap the Copilot key to function as the Right Control key or Context Menu key. Copilot already has a keyboard shortcut (Alt + Space) for those who want to use it, so having a dedicated key for a niche tool felt a bit like overkill.
Microsoft detailed the changes that are gradually rolling out.
