Introducing Cortana Show Me
Ever wanted to change a setting, but didn’t know how? Enter Cortana Show Me, your guide to Windows 10 settings, which is now available for download in the Microsoft Store through this link. In our preview app, Cortana will show you how to change settings step-by-step. In this release, you can launch guides directly from the app homepage, but check back soon for voice entry points. For Insiders, the app is available in English (US and UK) and in German. We’ve created guides for 15 settings so far but stay tuned for further improvements and additional offerings. While we know this experience isn’t specifically designed for Insiders, it’s for all the friends and family we have who need a pointer – please share it with them.
Original Story: Microsoft is now testing Windows 10 build 17128 internally. The new Windows 10 build 17128 (10.0.17128.1 rs4_prerelease.180318-1310) was compiled on March 18, 2018.
Windows 10 Spring Update preview build 17123 is now available for Insiders which has added a High-Efficiency Image File Format (HEIF) for Windows 10 and the Photos app.
This new feature leverages modern codecs like HEVC to improve quality, compression, and capabilities compared to earlier formats like JPEG, GIF, and PNG.
In addition to traditional single images, HEIF supports encoding image sequences, image collections, auxiliary images like alpha or depth maps, live images & video, audio, and HDR for greater contrast.
Windows 10 build 17123 ISO images are also now available for download. You can download it from the link below. The final Windows 10 Spring Update will release in April for everyone.
