  • Microsoft Unleashes Full Screen Experience to All Windows 11 Gaming Handhelds
    November 23, 2025, 1:06 AM EST. Microsoft has expanded the Full Screen Experience (FSE) from the Asus ROG Xbox Ally X to all current Windows 11 gaming handhelds, including the Lenovo Legion Go, MSI Claw 8 AI+, and AYANEO devices. The feature, which streamlines Windows for gaming by booting into a consolidated interface that gathers titles from stores like Windows Store, Steam, Epic Games, and Battle.net, can be tested via the Xbox/Windows Insider program. Early users can expect a streamlined UI, faster access to games, and reduced reliance on the Start menu. While some enthusiasts previously forced enablement via registry tweaks on version 25H2, the official expansion marks a broader adoption. The move mirrors concepts like Big Picture Mode and may pave the way for broader form-factor testing beyond handhelds, including home theater PCs.
  • Could Windows 11 Phone Shell Be Next? Xbox XFSE, Widgets, and ARM Windows
    November 23, 2025, 1:04 AM EST. Is the dream of a Windows 11 Phone Full Screen Experience really crazy? The article revisits the Xbox Full Screen Experience (XFSE) and nostalgia for Windows Media Center, and asks whether Windows 11 could become a sofa-friendly, TV-like UI controlled by an Xbox controller or remote. It notes that XFSE sits atop Windows, with limited apps today, but hints at future quick access to Netflix and web apps within the Xbox shell. The piece imagines a Start Menu Full Screen Experience, an expanded Windows 11 Widgets surface, and a more open mobile launcher concept. It also ties this to Windows on Arm, Copilot+ on PC, and the Snapdragon X Elite era, arguing that ARM-native Windows could power a new generation of Windows-powered devices. Not crazy, just plausible.
  • Ceva Stock Slumps on Dilution Fears After $19.50 Secondary Offering
    November 23, 2025, 1:00 AM EST. Shares of Ceva fell as the company priced a secondary offering, raising concerns about dilution.

The move triggered a sharp weekly drop, with the stock down more than 22% week-to-date. The article notes the risk of dilution to the existing float of about 27 million shares. The writer sees some AI market potential but urges caution until proceeds are deployed.
