Microsoft Retools Windows for Handheld Gaming PCs

Microsoft and ASUS have unveiled new handheld devices branded "ROG Ally X". But the real story isn't the hardware – it's the deep Windows changes specifically crafted for compact gaming systems.

The key feature is a full-screen Xbox mode that becomes the default startup experience. Users land directly in a simplified interface, ditching the traditional Windows desktop, taskbar, and wallpapers. When booting into this gaming mode, numerous background processes typical of desktop use are disabled. This frees up nearly 2GB of RAM for games and cuts power draw in sleep mode by a third compared to a standard desktop boot.

The interface builds on the revamped Xbox app and Game Bar. A quick tap of the Xbox button brings up quick settings for Wi-Fi, Bluetooth, ASUS's Command Center, and even a new "Gaming Copilot" assistant. Holding the button activates a task switcher optimized for controller use. The game library now aggregates titles not just from Xbox Game Pass, but also from Steam, the Epic Games Store, and other sources.

Importantly, this revamped gaming mode isn't exclusive to new hardware. It will debut on the ROG Ally X, then come to existing ROG Ally models (without the X branding), and eventually reach other Windows 11 handhelds. Microsoft also announced a Steam Deck Verified-like program to rate games for handheld PC optimization.

These moves are Microsoft's direct response to the popularity of SteamOS and the Valve Steam Deck. The company acknowledges it took three years to adapt Windows to mobile gaming realities, marking the start of a new phase in OS competition for this segment.
