Redmond, Washington, April 17, 2026, 11:35 (PDT).
Microsoft on Friday pushed a long-delayed Windows storage change closer to ordinary users and widened access to a new controller-first gaming interface, adding both a 2TB FAT32 formatting option and Xbox mode to Windows 11 Release Preview builds. The same batch of Insider updates also brought Xbox mode to a new Canary build, widening its reach across Microsoft’s testing tiers.
That matters because Release Preview is the track Microsoft uses for commercial customers and testers who want early access to production builds in the days before broader release. Landing there gives both features more weight than a routine Insider experiment.
In Release Preview builds 26100.8313 and 26200.8313, Microsoft said users would get Xbox mode on laptops, desktops and tablets, faster navigation in Settings on large storage volumes and a jump in the command-line FAT32 cap from 32GB to 2TB. The rollout is gradual, so availability will vary by device and market.
FAT32 is an older file system — the way a drive organizes stored data — that still shows up in boot media and some older hardware. Microsoft first tested the 2TB command-line formatter in Canary in August 2024, and Friday’s move into Release Preview suggests the change is finally edging toward mainstream Windows 11 builds.
The gain is real, but narrower than it sounds. Microsoft’s own deployment guidance says Windows install drives use FAT32 and warns that files larger than 4GB cannot fit on them, so the higher size cap does not remove FAT32’s biggest modern limit. Microsoft has only announced the larger cap for the command-line format tool.
The storage work fits a wider cleanup drive. Windows chief Pavan Davuluri wrote last month that users should see “tangible progress” this year as Microsoft focuses on “performance, reliability and well-crafted experiences,” with File Explorer and core responsiveness high on the list. Windows Blog
On gaming, Microsoft is trying to make Windows feel less like a desktop when players want a console-style session. Jason Ronald, Xbox’s vice president of next generation, said in March that Xbox mode would bring “a familiar Xbox experience” to Windows while keeping “the flexibility and openness of Windows.” Ian LeGrow, Microsoft’s corporate vice president for Windows + Devices, has described the feature as “purpose-built for gaming” and aimed at players who want a “console-like feel” on a PC.

Friday’s Canary build 29570.1000 lets testers launch Xbox mode from the Xbox app, Game Bar settings or by pressing Win+F11. Microsoft’s Dev and Beta builds released the same day were smaller, centered on File Explorer, Windows Hello, clipboard and settings reliability rather than fresh headline features.
The timing is notable. Valve is widening SteamOS support beyond the Steam Deck to other companies’ handhelds, while Microsoft said at GDC in March that Xbox mode would begin rolling out in April to all Windows 11 PC form factors in select markets.
But the new builds still come with the usual preview caveats. Release Preview features are being sent in phases, and Microsoft says availability will vary by device and market. Even with a 2TB cap, FAT32 remains bound by its 4GB per-file ceiling, and Microsoft warns Insider features can still change or disappear before they ship to everyone.
