Previewing Improved Windows Search on Copilot+ PCs with Windows Insiders in the Dev Channel

Windows 11 Insider Preview Build 26120.2992 (KB5050083) to the Dev Channel previewing improved Windows Search with Windows Insiders with Snapdragon-powered Copilot+ PCs.

New Copilot+ PC experiences

Improved Windows Search
We are making finding your documents, photos, and settings across Windows 11 easier on Copilot+ PCs by introducing semantic indexing along with traditional indexing. Whether it's searching in File Explorer, in the Windows search box 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. For example, you can use your own words to find images by typing "bridge at sunset", documents by describing what they are about like "Europe trip budget", or settings like "change my theme". 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.

Today, searching for files on your Copilot+ PC with improved Windows Search will only work for files saved locally in indexed locations on your PC. You can go to Settings > Privacy & security > Searching Windows to adjust which locations are indexed on your PC or turn on "Enhanced" to index your entire PC. In a future flight, we will support searching for documents and photos stored in cloud storage providers such as OneDrive.

Searching for settings like "change my theme" will work within the Settings app for now. In a future flight, you will be able to do this within the Windows search box on the taskbar.

These improved Windows Search experiences will gradually roll out to Windows Insiders on Snapdragon-powered Copilot+ PCs, with support for AMD and Intel-powered Copilot+ PCs coming soon. These experiences are supported in select languages (Chinese, English, French, German, Japanese, and Spanish) and document formats. Supported file formats include .txt, .pdf, .docx, .doc, .rtf, .pptx, .ppt, .xls, .xlsx for documents and .jpg/.jpeg, .png, .gif, .bmp, .ico for images. See here for more details.

You can learn more about semantic search on Copilot + PCs here.

FEEDBACK for File Explorer Search: Please file feedback in Feedback Hub (WIN + F) under Files Folders and Online Storage > File Explorer Search.

FEEDBACK for Windows Taskbar Search: Please file feedback in Feedback Hub (WIN + F) under Desktop Environment > Search.

FEEDBACK for Settings Search: Please file feedback in Feedback Hub (WIN + F) under Settings > Search Settings.

New text action for Click to Do (Preview)
You'll see a new text action for Click to Do available on Copilot+ PCs called Refine. To try this out, press Win + Click directly on a block of text or press Win + Q and then navigate to the text you'd like to proofread and refine. When you open the menu, the new action will be under Rewrite > Refine.

All the other actions you've seen in Click to Do are still here. If anything looks missing, please check the Microsoft Store for the latest Photos and Paint apps installed.

[Click to Do]

Changes and Improvements gradually being rolled out to everyone in the Dev Channel

[Windows Backup]

Releasing Windows 10 Build 19045.5435 to the Release Preview Channel

This update includes the following features and improvements (items bolded in brackets indicate the area of the change being documented) for Insiders who are on Windows 10, version 22H2:
