Microsoft has phased out support for Microsoft Defender Application Guard (MDAG), starting with its deprecation for Office applications in November 2023 and for the Edge browser in December 2023. By April 2024, MDAG was removed from Edge and other browser stores, and it was completely eliminated from Windows 11, version 24H2. Microsoft is finalizing the retirement of MDAG by discontinuing support in Edge entirely. The advisory MC1459132 indicates that this phase affects Microsoft Edge users on Windows 10, as Windows Information Protection (WIP) was already phased out in favor of Microsoft Purview in 2022. Organizations using WIP are advised to transition to Microsoft Purview Information Protection, Microsoft Purview Data Loss Prevention (DLP), Endpoint DLP, and Intune app protection policies. Users of MDAG should utilize Edge's built-in security features and consider other isolation solutions. Support for WIP and MDAG will officially end by September 2026, and functionalities related to them will stop in Microsoft Edge 154 and later versions. IT administrators are encouraged to begin migration activities to avoid disruptions.

Microsoft promoted the Copilot key on social media, branding it as a button with “main character energy,” despite acknowledging that it has negatively impacted productivity for some users. The company plans to allow remapping of the key in an upcoming Windows 11 update. User reactions to the promotion were largely critical, with many expressing dissatisfaction and calling for the removal of the Copilot key. Microsoft had previously admitted that the key caused disruptions in productivity and accessibility workflows. Additionally, only 3.3% of Microsoft 365 users are paying for Copilot, indicating low adoption. Microsoft has distanced its flagship products from the Copilot branding and users have reported preferring alternatives like ChatGPT and Claude over Copilot.
