The open-source Windows debloating tool Win11Debloat received a critical update on June 11, 2026, delivering long-sought fixes for the notoriously persistent Windows Spotlight feature, along with expanded capabilities to fully excise Microsoft’s artificial intelligence integrations and tighten telemetry blockades. Maintainer Raphire tagged the release ‘06.11.2026’ on GitHub, addressing escalating user frustration as Windows 11’s 24H2 update cemented Copilot and other AI services as core desktop elements that many privacy-focused users and enterprise administrators want to rip out completely.

What’s New in Win11Debloat 06.11.2026

The latest iteration arrives three months after the previous build and represents the most substantial overhaul of the script’s blocking logic since its inception. It tackles three stubborn areas where earlier versions fell short, especially on recent Windows versions.

Windows Spotlight Finally Tamed

Windows Spotlight has been a persistent nuisance for users who prefer a static lock screen or custom background. Despite Microsoft providing a toggle under Settings → Personalization → Lock screen, many found that after cumulative updates or even a simple reboot, Spotlight would creep back, downloading Bing images and occasionally injecting widgets and advertising suggestions. Win11Debloat 06.11.2026 settles the matter with a layered defense.

The script now simultaneously sets the Group Policy “Turn off all Windows spotlight features” (Administrative Templates → Windows Components → Cloud Content), kills the Microsoft.Windows.ContentDeliveryManager process, deletes the asset cache folders located at %SystemDrive%\Users\%username%\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets, and disables the associated scheduled tasks in Microsoft\Windows\CloudContent. Users who had given up on ever silencing Spotlight after upgrading to 24H2 report that the fix is reliable for the first time.

AI and Copilot: Gone, Not Just Hidden

Microsoft’s push to embed Copilot everywhere—taskbar, Edge sidebar, Microsoft 365 apps, and even local search—has drawn ire from those who see it as unwanted bloat. Previous versions of Win11Debloat could hide the taskbar button and remove the chat icon, but Copilot’s background services continued to run and consume resources. The 06.11.2026 release goes much further.

It now completely uninstalls the Copilot app package (Get-AppxPackage -AllUsers | Where-Object Name -like "*Microsoft.Copilot*" | Remove-AppxPackage) and disables the “Windows Copilot” runtime service by setting the Start value to 4 under HKLM\SYSTEM\CurrentControlSet\Services\CopilotSvc. For Enterprise editions, it also blocks delivery of the Microsoft 365 Copilot plugin via Office updates by adding a PreventCopilot DWORD under HKLM\SOFTWARE\Policies\Microsoft\Office\16.0\Common\OfficeUpdate. Additionally, the script strips AI-powered recommendations from File Explorer and Settings by modifying AllowOnlineTips and ShowRecommendations, which Microsoft had begun testing in Insider builds. The result is a desktop that behaves as if Copilot never existed—a stark contrast to Microsoft’s vision of an AI-saturated experience.

Telemetry Blocking Gets Granular

Telemetry suppression has always been a core strength of Win11Debloat, but Microsoft’s telemetry collection has grown more pervasive in Windows 11, with over 2,500 endpoints tracked by privacy monitors. The 06.11.2026 release introduces a three-tier system: Basic, Enhanced, and Complete.

  • Basic leaves the DiagTrack service running but sets the telemetry level to Security (0) via HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection\AllowTelemetry and adds firewall rules for the most intrusive marketing endpoints. This level is recommended for users who still need Windows Update health checks and the Microsoft Store to function fully.
  • Enhanced fully stops DiagTrack and the dmwappushsvc service, adds over 150 firewall rules blocking domains like vortex.data.microsoft.com and watson.telemetry.microsoft.com, and disables Office telemetry agents. This level may break some enterprise diagnostic tools but is safe for most home users.
  • Complete takes the nuclear option: it disables the Windows Error Reporting service, blocks peer-to-peer update optimization, removes the telemetry scheduled tasks, and sets additional registry keys such as DisableTelemetry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\DataCollection. Microsoft has long warned that setting telemetry to zero can impair Windows Update, but for users in air-gapped or highly secure environments, this level provides maximum isolation.

The expanded blocking reflects months of community-contributed endpoint lists, incorporating telemetry from newer components like Windows Health Insights and the Microsoft Family Safety service. Users can switch levels through the new graphical interface or by passing a -TelemetryLevel parameter in command line.

A Graphical Interface for the Masses

Perhaps the most welcome addition for non-technical users is the new graphical interface, built with .NET Windows Forms. Launching the script now presents a clean multi-tab window with checkboxes for each category: Remove Bloatware Apps, Disable Telemetry, Block AI Features, Fix Spotlight, and more. Hovering over an option shows a tooltip explaining potential side effects. This GUI dramatically lowers the barrier to entry; previously, running the script required at least some comfort with PowerShell, but now even novice users can select and apply their preferred debloat settings. The script still supports command-line parameters for unattended deployment, making it suitable for enterprise imaging processes.

How It Works and What to Expect

Win11Debloat is a standalone PowerShell script (.ps1) that requires no installation—users download the latest release from GitHub, right-click and select “Run with PowerShell,” or open an admin terminal and execute ./Win11Debloat.ps1. On first run, it creates a system restore point and a full registry backup before making any changes. The script is modular: all changes are reversible via a companion “undo” script, though Raphire notes that after major Windows feature updates, some modifications may need to be reapplied.

Compatibility spans Windows 10 22H2 through Windows 11 build 26100 (the latest generally available release as of mid-2026). Users on Insider builds should exercise caution, as Microsoft occasionally changes service names and package identities, but the community is quick to adapt.

The main trade-off is reduced functionality versus enhanced privacy and performance. Disabling telemetry entirely can break the “Get Help” app, prevent Windows Update from pre-fetching drivers, and starve Microsoft’s diagnostic tools of data that could identify failing hardware. However, for a growing cohort of users who view their PC as a tool rather than an extension of Microsoft’s ecosystem, these losses are inconsequential. Raphire’s documentation emphasizes that users should understand each toggle before flipping it—a responsible stance in an environment where many debloating scripts blindly rip out components.

Community Pulse and the Microsoft Cat-and-Mouse

While the dedicated Windows forum thread for this release is quiet, chatter on GitHub Issues and Reddit’s r/Windows10 and r/privacy communities has been buzzing. Early adopters celebrate the reliable Spotlight fix, with one user posting, “Finally, no more surprise ads on my lock screen after a Tuesday patch.” Others caution that Copilot removal can cause Edge to throw errors when trying to open the sidebar, though the script now patches that by disabling the sidebar search feature entirely.

The bigger picture is a familiar tussle: Microsoft monetizes the desktop through AI services and targeted content, while power users fight to reclaim control. Microsoft’s Defender occasionally flags debloating scripts as potentially unwanted software (PUP), and future Windows updates could introduce integrity checks that prevent tampering with system services. But the open-source nature of Win11Debloat means it evolves as quickly as the constraints. For now, the 06.11.2026 release stands as one of the most comprehensive privacy toolkits for modern Windows.

Win11Debloat’s recurring popularity underscores a gap in Windows’ own controls. Microsoft provides a smattering of toggles—some buried deep in the registry—but they are often reset during updates or simply ignore background data flows. The company faces antitrust scrutiny in several jurisdictions over bundling practices, and tools like Win11Debloat become a form of grassroots “consent enforcement.”

Performance gains are another driver. Disabling telemetry services and removing pre-installed apps can free up 200–400 MB of RAM on average systems, reduce CPU spikes from background indexing, and reclaim gigabytes of disk space from cached advertisements and AI models. For older hardware struggling under Windows 11’s requirements, this can transform a sluggish machine into a responsive daily driver.

Yet, no third-party script is without risk. Enterprise IT managers should pilot Win11Debloat on non-critical workstations before broad deployment; a misconfigured telemetry block could prevent Microsoft Endpoint Configuration Manager from receiving compliance data. Home users should create a full system image before running the script, even with the built-in restore point.

Looking Ahead

As Microsoft pushes toward Windows 12—expected in late 2026 or early 2027—the integration of AI will likely deepen, and telemetry collection will become even more enmeshed with basic OS functions. Win11Debloat’s maintainer acknowledges this challenge on the project’s roadmap: “Every new build presents new blobs of unwanted data collection; we’ll keep up as long as the community helps identify them.” The 06.11.2026 release is a snapshot of that ongoing effort, and its swift uptake confirms that the demand for a cleaner, more private Windows will not fade.

In a landscape where operating systems increasingly treat users as products, Win11Debloat gives a measure of power back to the people who simply want their PCs to work without sending a continuous stream of data to Redmond. For those willing to accept the trade-offs, this update makes Windows feel like a tool again—not a never-ending marketing funnel.
