Microsoft has pushed a new Windows 11 build to the Release Preview channel for Windows Insiders, and it introduces a full-screen Xbox mode, several File Explorer fixes, Copilot agents on the taskbar, tighter driver trust rules, and a handful of performance improvements. These changes are still in testing — they are not yet rolling out through regular Windows Update — but they give a clear picture of where Windows 11 is heading next.
Applies to: Windows 11 (25H2 Release Preview channel) | Last updated: April 24, 2026
Key Takeaways
- A new full-screen Xbox mode is being added to all Windows 11 PCs — laptops, desktops, and tablets — giving the system a console-style home screen.
- File Explorer gets real fixes, including the long-standing white flash in dark mode when launching to This PC, faster launch performance, and consistent folder view settings across apps.
- Copilot agents are coming to the taskbar, starting with the Microsoft 365 Copilot researcher agent — Windows will show live progress on the taskbar while an agent is working.
- Dynamic app removal lists are being added to the existing “Remove default Microsoft Store packages” policy, but this remains an Enterprise and Education feature only.
- Cross-signed drivers lose default trust, and a new registry mode prevents batch files from being modified during execution — both are aimed at closing common malware paths.
Quick Summary of What’s New:
- Full-screen Xbox mode for all Windows 11 devices
- File Explorer dark mode flash fix, faster launch, and consistent folder views
- “Preview anyway” button for files downloaded from the internet
- Expanded archive format support in File Explorer
- Copilot agents displayed on the taskbar with live progress
- Dynamic app removal list for Enterprise and Education
- Default trust removed for cross-signed drivers
- Security mode that blocks batch files from changing during execution
- Memory and reliability improvements for the taskbar and startup apps
A Quick Note on the Release Preview Channel
Everything covered here is currently locked to the Release Preview channel of the Windows Insider Program. That means these features are still being tested, and they can change or be pulled before they reach the version of Windows 11 most people are running. If you are not enrolled as a Windows Insider, you will not see any of these changes yet through normal Windows Update.
I treat release preview builds as a preview of intent rather than a guarantee. Some of these features will ship more or less as-is, others will get reworked, and a few may disappear entirely. I will update this post as these changes move into the mainstream Windows 11 release.
Full-Screen Xbox Mode on Every Windows 11 PC
The first thing in this build is a new Xbox mode that gives Windows 11 a full-screen, console-style interface. Microsoft is rolling it out to all PCs — laptops, desktops, and tablets — not just handhelds. The home screen picks up where you left off with recent games and surfaces featured titles, similar to the Xbox console dashboard.
I personally do not use the Xbox app on Windows, so I cannot say how much of an improvement this is over what was already there. If you do a lot of gaming on your PC and want the Xbox app without going through the Microsoft Store, I covered that in a separate guide on installing the Xbox app on Windows without the Microsoft Store.
File Explorer Changes (The Ones I’m Actually Excited About)
The File Explorer changes are the part of this build I care about the most. There are five notable improvements, and most of them target long-standing annoyances rather than new features.
Consistent Folder View Settings Across Apps
Custom folder settings — like sorting files by name — now persist across every way you open that folder. If you set a folder to sort by name in File Explorer, then open the same folder from a web browser or another app, the sort order carries over automatically. This has been a small but persistent inconsistency for years.
Faster File Explorer Launch
Microsoft says they have improved the speed and performance of launching File Explorer. This covers both the general launch time and the specific case of opening to This PC or resizing the details pane. On systems where File Explorer sometimes takes a second or two to appear, this should feel noticeably snappier.
The Dark Mode White Flash Is Fixed
If you run Windows in dark mode and have File Explorer set to launch to This PC, you have almost certainly seen the white flash when File Explorer opens. It is a brief but genuinely annoying flash of bright white before the dark theme kicks in. Microsoft has finally fixed that in this build. For anyone who sets File Explorer to open directly to This PC, I have a separate guide on setting File Explorer to launch to This PC via the registry.
“Preview Anyway” Button for Downloaded Files
For files downloaded from the internet, the preview pane in File Explorer now shows a viewing warning first. Once you acknowledge it, a “Preview anyway” button lets you see the file contents. It is a small usability improvement on top of the existing Mark of the Web (MOTW) protection, which already restricts downloaded files from running without a prompt.
Expanded Archive Format Support
File Explorer now recognises and works with a wider list of archive formats natively. This is a continuation of the archive handling Microsoft started adding in Windows 11 — you get more formats supported without needing a third-party tool for common extracts. For power users, I still recommend using a dedicated archive tool for heavy work, but for one-off extracts, the built-in support is now much more complete.
Explorer.exe Process Cleanup
Microsoft has also improved the reliability of explorer.exe processes stopping after you close File Explorer windows. There was a bug where these processes were not being cleaned up, which left background processes running and eating system resources for no reason. If you have ever noticed Task Manager showing multiple Windows Explorer entries after closing all your File Explorer windows, this is the fix for that.
Copilot Agents on the Taskbar
This is the one that is going to be controversial. Windows is adding a new way to monitor AI agents directly from the taskbar. The feature supports agents across both first-party and third-party apps, with the researcher agent in the Microsoft 365 Copilot app as the first adopter.
Here is how it works in practice. When the researcher agent is working on a report, Windows shows the progress on the taskbar, so you can glance down and see where it is at. Hovering over the Microsoft 365 Copilot icon displays real-time progress, and when the report finishes, Windows notifies you. The mechanism itself is not limited to Microsoft — third-party apps can plug into the same taskbar progress surface for their own agents.
My take: I am not anti-AI. I use Claude and Claude Code every day for my work, and I am actively setting up a personal AI assistant — just on a separate machine on my network, not on my main PC where all my personal data lives. My concern is not AI itself, it is Microsoft bundling Copilot into the operating system in a way that is hard to opt out of. If you feel the same way, you may want to disable Copilot in Windows 11 and 10, or remove AI apps from Windows 11 entirely.
Microsoft has also said in a previous post that they want to change the way AI is integrated into Windows. How that actually plays out with the taskbar agents feature will tell us a lot. I will update this post once it is clearer whether this stays opt-in or quietly becomes default behaviour.
Policy-Based Removal of Preinstalled Microsoft Apps
Microsoft has updated the existing policy that lets administrators remove default Microsoft Store packages. The update adds support for a dynamic app removal list, meaning administrators can add an AppX package name and have it removed automatically when the policy is applied. In practice, this makes it easier to remove default Microsoft Store bloatware across a managed fleet of PCs.
The catch is that this is still limited to Windows 11 Enterprise and Education. Pro and Home users do not get this policy. I would genuinely like to see Microsoft extend it to Pro — there is no good reason an advanced home user or small business on Pro should have fewer tools to manage bloatware than an Enterprise admin. I covered the original version of this policy in my guide on the official bloatware removal method in Windows 11 25H2.
If you are on Home or Pro: you do not need to wait for Microsoft. Winhance, the customization utility I built, already lets you remove preinstalled Microsoft Store apps, disable telemetry, and customize Windows 11 without needing Enterprise policies or the command line.
Driver Trust and Security Changes
There are two security-focused changes worth knowing about: a driver policy update and a new batch file protection mode.
Cross-Signed Drivers Lose Default Trust
Windows 11 is removing the default trust for cross-signed drivers. Drivers from the Windows Hardware Compatibility Program and an allow-list of trusted legacy drivers are still permitted, but the blanket acceptance of cross-signed drivers is going away. This is a straightforward security hardening — cross-signed drivers have been a common vector for malicious or abusable kernel code for years.
Batch File Execution Protection
There is a new registry-based mode that prevents batch files from being modified during execution. If a batch file tries to change itself mid-run — for example, to call another script that gets swapped in at runtime — it will be blocked. This closes off a known technique used by some malware that rewrites scripts on the fly to evade detection.
Note: This is an opt-in mode set via a registry key. It is not enabled by default, and most everyday scripts will not be affected, but administrators running hardened environments will want to turn it on.
Microsoft Store, Taskbar, and Performance Fixes
The rest of the build is a collection of smaller reliability and performance improvements. They are not headline features, but a few are worth noting:
- Fewer unexpected Microsoft Store download errors — Microsoft has cleaned up a set of common failure cases when pulling apps from the Store.
- Taskbar system tray reliability — the system tray area now loads more consistently for Windows Update when Delivery Optimization is in use.
- Lower taskbar memory usage — reducing the likelihood of the taskbar allocating an unexpectedly large chunk of RAM.
- Faster startup app launches — the apps that load when Windows boots should start up faster after login.
- General reliability work on Explorer, taskbar flyouts, and File Explorer’s Quick Access.
I personally disable Delivery Optimization on every machine I set up, so the taskbar system tray fix does not affect me. If you do use Delivery Optimization, this should at least make the experience lighter on memory.
What This Build Tells Us About Windows 11’s Direction
A lot of this build is Microsoft delivering — or starting to deliver — on things they promised in earlier Windows 11 posts. Some of that delivery is solid: the File Explorer fixes, the driver trust changes, the batch file protection. Other parts feel off-direction: Copilot agents on the taskbar is not what most of the people I talk to are asking for in Windows. It is an early release preview build, so things will change before anything reaches production, but it is a useful signal for where Microsoft’s focus currently sits.
If you want full control over how much of Microsoft’s ecosystem is active on your PC, I would strongly recommend checking out Winhance. It is free, open source, and built specifically to give Windows users the removal and customization options Microsoft does not ship by default.
Frequently Asked Questions
When will these Windows 11 features reach the public?
There is no fixed date. Features in the Release Preview channel typically ship to the public within a few weeks to a few months, but Microsoft can pull, delay, or rework any feature before general release. Cumulative quality updates from the Release Preview channel usually roll out fastest; larger feature additions like Xbox mode or Copilot agents tend to be tied to broader Windows 11 feature updates.
How do I join the Release Preview channel to try these features now?
Open Settings, go to Windows Update, then Windows Insider Program. Sign in with a Microsoft account, pick the Release Preview channel, and reboot. Release Preview is the most stable of the Insider channels and only receives builds close to production, so it is generally safe on a daily-driver PC. I still recommend a full backup before enrolling any machine.
Can I disable Copilot agents on the taskbar?
The exact opt-out controls are not fully documented in this preview build yet, so the final answer depends on what ships. If you want to remove Copilot entirely today, follow my guide on enabling or disabling Copilot in Windows 10 and 11. For broader AI and bloat removal, Winhance is the cleanest path.
Does the dynamic app removal policy work on Windows 11 Home or Pro?
No. The “Remove default Microsoft Store packages” policy — including the new dynamic list — is limited to Windows 11 Enterprise and Education. Home and Pro users need to remove preinstalled apps another way. Winhance does this cleanly, or you can follow my written guide on the official bloatware removal method in Windows 11 25H2.
Is the batch file execution protection enabled by default?
No. The new mode that blocks batch files from changing during execution is opt-in through a registry key, so existing scripts and automation will continue to work as they do today. It is intended for hardened and managed environments, not general consumer use.
