[Improved Windows Search]
-
New! Finding your documents, photos, and settings across Windows 11 is easier on Copilot+ PCs with improved Windows Search, powered by semantic indexing models along with traditional lexical indexing. Whether it’s searching in File Explorer, in the Windows Search on your taskbar, or in Settings – just type what’s on your mind to find it on your Copilot+ PC. You no longer need to remember file names, exact words in file content, or settings names. Searching for settings like “change my theme” will work within the Settings app for now. Thanks to the power of the 40+ TOPS NPU onboard Copilot+ PCs, these search improvements work even when you’re not connected to the internet. For more info, see semantic search on Copilot+ PCs. Available on Snapdragon-powered Copilot+ PCs, with support for AMD and Intel-powered Copilot+ PCs coming soon.
-
New! Locating your photos stored and saved in the cloud is getting simpler on Copilot+ PCs You can use your own words in the search box at the upper-right corner of File Explorer like “summer picnics”. In addition to photos stored locally on your Copilot+ PC, photos from the cloud will now show up in the search results together. Exact matches for your keywords within the text of your cloud files will also show in the search results. You can try this experience out today with your personal OneDrive when signed in with your Microsoft account and connected to the internet. To learn more, see semantic search on Copilot+ PCs. Available on Snapdragon-powered Copilot+ PCs, with support for AMD and Intel-powered Copilot+ PCs coming soon.
