Microsoft is taking another swing at solving the biggest problem with Windows-based gaming handhelds: Windows itself.

The company just announced that its new Xbox Full Screen Experience (FSE) is rolling out in preview to the MSI Claw. The feature, included in the latest Windows 11 Insider Preview Build, aims to finally deliver on the promise of a seamless, console-like interface for your portable PC.

This is the second major device family to get the feature, which debuted on the ASUS ROG Ally and its “Xbox” branded Ally X sibling earlier this month. On paper, it’s the update handheld gamers have been begging for—a clean, controller-first interface that boots you straight into your games, just like a Steam Deck.

But based on the rocky rollout on the Ally, this “Full Screen Experience” is still more of a promising beta than a polished revolution. And if you’re an MSI Claw owner, you might want to hold off on joining the Windows Insider program just to get it. The dream is tantalizingly close, but the reality is still, well, a bit buggy.

What is the ‘Full Screen Experience,’ anyway?

Let’s be clear about what this feature is and what it isn’t. It is not a new operating system. It is not Microsoft’s version of SteamOS.

At its core, the Xbox Full Screen Experience is essentially a clever “wrapper.” When you enable it, Windows 11 boots directly into the Xbox PC app, bypassing the traditional desktop, taskbar, and Start menu entirely.

Behind the scenes, it’s a dedicated “game mode” that aggressively minimizes background processes and defers non-essential tasks. The goal, according to Microsoft, is to deliver “smooth task switching and optimized performance.” In practice, this means it deactivates parts of Windows you don’t need for gaming—like certain networking protocols and the desktop shell itself—to free up precious system resources, particularly RAM.

For anyone who has fumbled with a tiny touchscreen icon or cursed as the on-screen keyboard covered the very login field they were trying to type in, this sounds like a godsend. It’s Microsoft’s official attempt to tame the “bloated” nature of its own OS and stop it from stealing performance from your games.

The cautionary tale of the ROG Ally

To understand why you should be cautious, we just have to look at the experience of “early adopters” who have been using this on the ASUS ROG Ally for the last few weeks. The consensus is that while it’s a great idea, the execution is “half-baked” and “woefully inconsistent.”

Hands-on reports from numerous tech outlets and users on forums like Reddit paint a picture of a feature that needs a lot more time in the oven.

The list of “weird quirks” is long:

• UI bugs galore: Users report frequent hangs, a UI that occasionally stops responding to input, and frustrating sync issues where new games just don’t appear in the library.
• The desktop’s revenge: The FSE is designed to hide the desktop, but if you ever need to exit to it—say, to install a non-Xbox launcher or tweak a setting—getting back is a nightmare. Most users report that the only way to re-enter the Full Screen Experience is to do a full system reboot.
• Death by a thousand clicks: The login screen still requires you to tap the PIN box before you can enter your code—a small but constant reminder that you’re in Windows. The virtual keyboard frequently blocks the text boxes you’re trying to use.
• Performance is… debatable: The biggest promise was a boost to gaming, but the results are mixed. While most testers agree the FSE frees up about 1GB to 1.5GB of RAM, this doesn’t always translate to more frames. Some benchmarks show a respectable 11% boost in Cyberpunk 2077, while others show no meaningful change at all. Critically, it’s still “no match” for the performance of Linux-based alternatives like SteamOS, which can squeeze as much as 30% more performance out of similar hardware.

For Ally users, the FSE is a step in the right direction, but it’s a clumsy one. It’s still a layer on top of Windows, and the cracks show through everywhere.

The glimmer of hope: why it might be better on the Claw

Here, however, is the fascinating twist. The experience on the MSI Claw might actually be better.

Early reports from MSI Claw owners in the Windows Insider program are surprisingly positive, with some calling it a “total game-changer.” The reason has less to do with Microsoft and more to do with MSI.

Unlike the Ally, MSI has apparently been updating its own “MSI Center M” software to integrate directly with the new Xbox feature. According to one Insider, a new update to the Claw’s BIOS and software enables a “brilliant” new shortcut: you can simply hold the MSI Quick Settings button to instantly open the Task Viewer.

This single integration could solve one of the biggest complaints from Ally users—the clunky, reboot-heavy process of switching between the game mode and the desktop. If you can seamlessly pop open a task switcher with a dedicated hardware button, the FSE suddenly becomes a flexible tool rather than a restrictive cage.

This suggests that the “Full Screen Experience” won’t be a one-size-fits-all solution. Its usability will depend heavily on how well each manufacturer—be it MSI, ASUS, or Lenovo—integrates it with their own hardware and software.

So, while Microsoft has laid the foundation, it’s MSI that’s building the features that actually make it usable.

Don’t rush, but stay tuned

The Xbox Full Screen Experience is, without a doubt, the future of Windows on handhelds. But it is not the present.

The news that it’s coming to the MSI Claw is fantastic. But the user’s prompt to “wait until some of the problems are ironed out” is the most professional-grade advice you could get.

Microsoft is clearly prioritizing rapid deployment over polish, likely in a rush to compete with the Steam Deck’s seamless experience. The result is a buggy, inconsistent, and sometimes frustrating public preview.

If you’re a casual MSI Claw user, stay put. Let the Insiders find the bugs. Wait for the feature to graduate to a stable, public release. By then, Microsoft will hopefully have patched the “weird quirks,” and MSI will have had even more time to perfect its software integration.

The console-like Windows handheld is coming. It’s just not here quite yet.
