What’s new in Build 27938
Introducing AI actions in File Explorer
With AI actions in File Explorer, you can interact more deeply with your files by right-clicking to quickly take actions like editing images or summarizing documents. Like with Click to Do, AI actions in File Explorer allow you to stay in your flow while leveraging the power of AI to take advantage of editing tools in apps or Copilot functionality without having to open your file. AI actions in File Explorer are easily accessible – to try out AI actions in File Explorer, just right-click on a file and you will see a new AI actions entry on the content menu that allows you to choose from available options for your file.
Today, you can try one of four image actions for seamless editing or web searches with images:
- Bing Visual Search: Allows you to search the web using an image instead of text. Find similar images and products, get details about sites using the image, and identify landmarks, plants, and famous faces. From searching what you see on your screen, to shopping your preferred style, getting help with that homework problem, or translating text, getting answers is more intuitive than ever.
- Blur Background: Opens the Photos app which automatically finds the background in the photo, and with a single click, instantly highlights your subject and blurs out the background. You can also customize the effect by adjusting the Blur Intensity or use the Brush Tool to modify the areas being blurred.
- Erase Objects: With Photos by selecting or highlighting an unwanted element in your photo and Generative Erase makes it disappear. It allows you to fix and remove distractions from your photos.
- Remove Background: With Paint allows you to alter any image automatically in just one click leaving a smooth cutout of the subject. Background removal can detect the subject from the entire canvas or using the selection tool.
These four image actions currently support these file types: .jpg, .jpeg, and .png.

In the meantime, if you are impacted, you can use the “Send Feedback” button in PIX or contact us on the DirectX Discord server and we can help provide private builds.
[Graphics]
- We’re investigating an issue which is causing some Insiders to experience screen flickers when using the browser (and potentially other scenarios) in the latest Canary builds.
[Audio]
- [NEW] Some Windows Insiders in the Canary Channel are experiencing an issue where audio stops working and Device Manager shows one or more devices with a yellow exclamation mark, including “ACPI Audio Compositor” and others. Selecting Properties on these devices will show “Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.” If you are impacted by this issue, you can follow these instructions to get back into a working state:
- Right-click on the device with a yellow exclamation mark in Device Manager and select “Update driver”.
- Choose “Browse my computer for drivers” and then “Let me pick from a list of available drivers on my computer”.
- Select the driver from the list with the most recent date and click “Next”. If you are presented with a list of common hardware types instead of one or more specific drivers, this device is not related to this issue.
- This device should be repaired and no longer show a yellow exclamation mark in Device Manager. If it continues to show a yellow exclamation mark, the yellow exclamation mark is not related to this issue.
- Repeat these steps for each device with a yellow exclamation mark.
