Improved Windows Search

Gradual rollout 2 items

For: Insiders with AMD- or Intel-powered Copilot+ PCs

  • On Copilot+ PCs, you can search for documents, photos, and settings by describing what you mean in your own words. Search works offline, too.7
    Uses semantic indexing alongside traditional indexing. Settings searches work within the Settings app for now; taskbar support is planned for a future flight. Supported languages and file formats are limited.
  • Search can find photos saved in the cloud alongside photos on your PC, and show exact keyword matches in cloud-file text.8
    Personal OneDrive photo results require a Microsoft account and an internet connection. With a work or school account (Entra ID), results include keyword matches in cloud-file text, not photos.
