Microsoft [finance:Microsoft Corporation] just made its boldest move yet to compete with Valve’s Steam Deck dominance. The Xbox Full Screen Experience officially launched November 21, 2025 for all Windows 11 handheld gaming devices, transforming them into Xbox-branded consoles that boot directly into a controller-navigable interface. Even more ambitious, the feature is now rolling out in preview to desktops, laptops, and tablets through the Windows Insider Program, bringing console-style gaming to every Windows 11 PC.
This isn’t just a cosmetic change. The Full Screen Experience bypasses the Windows Explorer shell entirely, freeing up approximately 2GB of system memory by eliminating unnecessary background processes. It delivers a clean, distraction-free gaming environment where you can launch titles from Xbox Game Pass, Steam, Epic Games Store, Battle.net, and other PC storefronts using only a controller. No keyboard required. No desktop clutter. Just games.
What Is Full Screen Experience
The Xbox Full Screen Experience transforms Windows 11 into a console-like interface designed specifically for controller-first navigation. When enabled, your device boots directly into the Xbox app without loading the traditional Windows desktop. The interface presents your entire game library across all installed launchers in a unified, easily browsable format that feels identical to navigating an actual Xbox console.
A powerful Task Switcher enables quick movement between games and apps without returning to the desktop. You can jump from playing a Game Pass title to launching a Steam game to checking Discord without ever touching a keyboard or mouse. The seamless experience eliminates the friction that has plagued Windows handheld gaming since these devices emerged as alternatives to the Steam Deck.
The performance benefits come from architectural changes rather than simple UI tweaks. By not loading Explorer.exe and suppressing numerous background processes typical of a standard Windows 11 setup, the system conserves roughly 2GB of RAM. That memory becomes available for games, directly improving frame rates and reducing stuttering, particularly on devices with 16GB or less total system memory.
How It Works Technically
Full Screen Experience operates by modifying Windows 11’s boot sequence to skip the standard desktop environment. Instead of Explorer.exe becoming the primary shell, the Xbox app takes over as the interface layer. Background services still run when necessary, but dozens of processes that would normally consume resources sitting idle are simply never loaded.
The feature works on both x86 architecture using Intel and AMD processors and ARM64 devices, positioning Microsoft for the growing wave of ARM-based gaming PCs expected to proliferate following Qualcomm’s Snapdragon X Elite chip success. This architecture flexibility ensures Full Screen Experience remains relevant regardless of which processor technology dominates future Windows devices.
Users can toggle Full Screen Experience on or off through Windows Settings under the Gaming tab. You can set it to activate automatically at boot or manually launch it from within the Xbox app. Pressing Windows plus F11 switches between Full Screen Experience and traditional desktop. The flexibility means you’re never locked into one mode, maintaining Windows’ core advantage of being a full PC when you need it.
Rollout and Availability
Full Screen Experience became generally available for all Windows 11 handhelds starting November 21, 2025. This includes devices like the ASUS ROG Ally and Ally X, MSI Claw, Lenovo Legion Go, and any other Windows-based gaming handheld currently on the market. The feature was previously exclusive to the ROG Ally X through a partnership with ASUS, but Microsoft has opened it to the entire ecosystem.
For desktops, laptops, and tablets, Full Screen Experience is rolling out gradually through the Windows Insider Program starting with Build 26220.7271 in the Dev and Beta channels. Not all Insiders will receive access immediately due to the phased deployment, but anyone enrolled in both Windows Insiders and Xbox Insiders should gain access within weeks.
The desktop expansion represents Microsoft’s answer to Steam’s Big Picture Mode, which has provided controller-friendly PC gaming interfaces for over a decade. Where Big Picture Mode requires launching Steam specifically and only manages your Steam library, Full Screen Experience works as a system-wide interface managing games across all storefronts while providing genuine performance improvements through memory savings.
System Requirements
Full Screen Experience requires Windows 11 version 25H2 or newer and the latest Xbox app from the Microsoft Store. Technically, any Windows 11 device meeting those requirements can run it, though Microsoft officially restricts availability to specific form factors through feature flags. Enthusiasts have discovered workarounds using tools like ViVeTool and registry edits to enable the feature on unsupported devices, though Microsoft warns this may cause stability issues.
Performance gains scale based on available system memory. Devices with 8GB of RAM see the most dramatic improvements since the 2GB savings represents 25 percent of total memory. Systems with 32GB won’t notice memory differences but still benefit from reduced background process overhead. Battery life improvements on handhelds come primarily from the efficiency of running fewer services rather than memory savings specifically.
The Steam Deck Problem
Understanding Full Screen Experience requires understanding why Microsoft built it. Valve’s Steam Deck launched in 2022 and completely changed expectations for handheld PC gaming. Running a custom Linux-based SteamOS, the Deck provides a polished, console-like experience where games just work. No driver installations. No Windows updates interrupting gameplay. No desktop clutter. It boots to your game library and gets out of the way.
Windows handhelds struggled to compete because Windows 11 wasn’t designed for 7-inch touchscreens and controller navigation. Launching a game required navigating desktop interfaces built for mouse and keyboard. Updates demanded user intervention. Anti-cheat systems sometimes refused to work. The Windows advantage of running everything became a liability when everything meant dealing with desktop PC complexity.
Full Screen Experience directly addresses every complaint levied at Windows handhelds. Boot to games? Check. Controller navigation throughout? Check. Unified library regardless of storefront? Check. Performance improvements over traditional desktop? Check. If Microsoft executes properly, Windows handhelds could finally deliver experiences matching or exceeding SteamOS without requiring users to abandon their existing game libraries or give up Windows compatibility.
Valve’s Response
Valve isn’t sitting idle. The company announced a refresh of its Steam Machine concept targeting late 2025 or early 2026, bringing SteamOS to traditional gaming PCs rather than just the Steam Deck. This creates a fascinating three-way competition between Windows with Full Screen Experience, SteamOS expanding beyond handhelds, and traditional Windows desktops.
The new Steam Machines will run SteamOS natively, offering the same streamlined experience as Steam Deck on full-power desktop hardware. For players primarily invested in Steam’s ecosystem who don’t need Windows-specific games or applications, this provides console simplicity with PC performance. Microsoft’s Full Screen Experience represents the counterargument that Windows can match that simplicity while maintaining compatibility advantages.
Real World Performance
Early testing from users with access to Full Screen Experience shows mixed but generally positive results. One ROG Ally user reported Red Dead Redemption 2 improving from 35 to 37 average FPS during benchmarks, representing roughly 5 percent gains. Less demanding titles like Celeste saw RAM usage drop from 10.6GB to 9.4GB, saving over 1GB of memory that would otherwise sit allocated to Windows services.
The memory savings don’t always translate directly to FPS improvements in GPU-bound games where VRAM rather than system RAM limits performance. But for CPU-limited scenarios or games that aggressively use system memory, the 2GB savings provides meaningful headroom. Battery life improvements appear more consistent, with users reporting 15-30 minute extensions on handheld devices from reduced background process overhead.
The experience isn’t perfect yet. Multiple users report needing keyboard and mouse access for troubleshooting when something breaks. Certain failure points force you back to desktop mode to fix issues. Some games launched through Full Screen Experience don’t properly recognize controller inputs, requiring workarounds. These are early access problems that Microsoft will presumably address, but they demonstrate the feature needs refinement before general release.
Comparison to Big Picture Mode
Steam’s Big Picture Mode has existed since 2012, providing a mature controller-friendly interface refined over 13 years of development. Full Screen Experience launched in preview in 2025, making it significantly less polished. Big Picture Mode offers extensive customization, community controller configurations, and deep integration with Steam features like broadcasting and workshop content.
Where Full Screen Experience wins is scope and performance. Big Picture Mode only manages Steam games and still runs on top of Windows consuming full system resources. Full Screen Experience manages all your games regardless of storefront while actually reducing system overhead. If you only play Steam games, Big Picture Mode remains more feature-rich. If you use Game Pass, Epic, Battle.net, and multiple launchers, Full Screen Experience provides unified access Big Picture Mode cannot match.
Industry Implications
Full Screen Experience represents Microsoft’s most aggressive move yet to defend Windows’ gaming dominance against Linux-based alternatives. SteamOS proved that gaming PCs don’t require Windows if the alternative provides good enough compatibility and user experience. Microsoft cannot allow that precedent to solidify or risk losing gaming as Windows’ killer app keeping consumers on the platform.
The timing aligns with Microsoft’s broader gaming strategy under Xbox leadership. Game Pass integration provides exclusive value proposition that SteamOS cannot replicate without Microsoft’s cooperation. Full Screen Experience leveraging Windows’ core compatibility advantage while matching SteamOS’ interface convenience creates a powerful argument for staying in the Microsoft ecosystem.
For hardware manufacturers like ASUS, MSI, and Lenovo, Full Screen Experience removes a major competitive disadvantage against the Steam Deck. Windows handhelds can finally market themselves as providing console-like experiences rather than requiring disclaimers about navigating desktop interfaces. The playing field levels, allowing hardware specs and build quality to differentiate products rather than operating system shortcomings.
The Future of PC Gaming
If Full Screen Experience succeeds, it fundamentally changes PC gaming interfaces. We could see desktop gaming PCs defaulting to console-like interfaces while retaining desktop access when needed. The traditional Windows desktop might become optional for gaming-focused machines rather than mandatory. This mirrors how phones evolved from smartphone interfaces layered over mobile operating systems to touch-first designs where traditional desktop UIs became secondary.
The ARM64 compatibility positions Microsoft for a potential future where Qualcomm or other ARM chip manufacturers deliver gaming-capable processors at laptop power efficiency. Apple’s M-series chips proved ARM can match or exceed x86 performance in many scenarios. If ARM gaming PCs become viable, Full Screen Experience provides the interface layer making that transition seamless for users.
Getting Access Now
If you own a Windows 11 handheld, Full Screen Experience should be available now through the Xbox app. Check for updates in the Microsoft Store to ensure you have the latest version. Open Settings, navigate to Gaming, and look for the Full Screen Experience option. Toggle it on and restart your device to begin using the new interface.
Desktop, laptop, and tablet users need to join both the Windows Insider Program and Xbox Insider Program to access the preview. Enroll in the Dev or Beta channel for Windows Insiders, then download the latest preview build 26220.7271 or newer. Install Xbox Insiders from the Microsoft Store and opt into receiving preview features. Full Screen Experience should appear in your Gaming settings within days to weeks depending on rollout timing.
Enthusiasts comfortable with advanced tools can force-enable the feature on unsupported devices using ViVeTool, registry edits, and PSTools to bypass Microsoft’s restrictions. Multiple YouTube tutorials and community guides detail the process. However, Microsoft warns that enabling features through unsupported methods may cause system instability and isn’t recommended for average users.
