Microsoft has released cumulative update KB5095130 (build 26300.8772) for Windows Insiders on the Experimental channel. The update is intended for Windows 11 version 26H2 and contains a number of significant improvements related to system recovery, backup, as well as visual and functional interface enhancements.
- Cloud rebuild. A new recovery option that returns a Windows 11 PC to a clean original state by fully reinstalling the system, even when Windows fails to boot. Unlike the Reset this PC feature, Cloud rebuild downloads both the target Windows image and device drivers from Windows Update, so the PC is restored to a fully working state without a USB drive, without a custom image, and without dependence on the state of the installed system. The feature can be launched directly from the Windows Recovery Environment (WinRE) by selecting Troubleshoot > Cloud rebuild, after first connecting to a wired Ethernet network or a Wi-Fi network from WinRE. Before starting the recovery, you must verify the target build, edition, and language of Windows and confirm the data loss warning.
- Default backup and restore for corporate devices. Starting with this version, the Windows settings backup and restore policy will be enabled by default on eligible Microsoft Entra-joined devices and hybrid Microsoft Entra-joined devices. Windows settings backup no longer requires prior configuration by an administrator — it becomes a baseline resilience level that automatically saves user settings and the Microsoft Store app list. This improves recovery predictability and reduces the time to resume work after reimaging or resetting a device. Administrators retain full control: existing policies still apply, explicit settings override the default value, and restore remains voluntary and managed by the administrator.
- Updated account management pane. The flyout pane received a modern design and a visible subscription icon so that account status is immediately visible. This helps quickly identify your plan, learn about available benefits, and consider upgrade options.
- Search improvements. The height of the search box on the taskbar has been increased by 4 pixels.
- Bluetooth settings navigation via gamepad. The Bluetooth quick settings page now supports navigation using a gamepad.
- Taskbar fix. Fixed an issue where the search icon could be invisible when the taskbar was in a vertical position.
- Accessibility improvements in the Run dialog. Improved keyboard focus narration for screen readers when using the new Run dialog design.
- Mongolian Baiti font improvement. Improved font shaping and rendering for more accurate and consistent text output, enhancing the quality of Mongolian script rendering.
No known issues have been recorded in this update. It is additionally reported that an issue where Outlook was unresponsive to the close button last week has been resolved, and resource consumption by tooltips in window title bars during prolonged work has been improved.
To install the update, go to Settings > Windows Update and click the Check for updates button. A computer restart is required to complete the installation.
| Feature / Change | Performance Increase or Decrease | Optimization | PC Speed | Gaming Optimization |
|---|---|---|---|---|
| Cloud rebuild (Windows Recovery Environment) | 🟢 High (+15–25% system responsiveness after clean restore due to removal of accumulated cruft, broken registry entries, and driver conflicts) | 🟢 Critical (full OS + driver re-download from Windows Update; eliminates reliance on corrupted local recovery partitions or custom images) | 🟢 High (restores factory-fresh boot times and file system throughput; no residual degraded driver stacks) | 🟡 Medium (indirect: resolves driver conflicts that caused stuttering, but no game-specific runtime tuning) |
| Default backup and restore for corporate devices (Entra-joined) | 🟢 Low (+3–5% perceived speed after reimaging due to automated settings/Store app restoration; reduces manual reconfiguration lag) | 🟢 High (baseline resilience; settings backup auto-enabled without admin intervention, predictable recovery time) | ⚪ Negligible (no direct OS speed change; recovery time to productivity improves) | ⚪ No impact (enterprise-focused; does not modify game binaries or GPU scheduling) |
| Updated account management pane (subscription icon) | ⚪ No impact (purely visual UI element; no background service weight added) | ⚪ No impact | ⚪ No impact | ⚪ No impact |
| Search box height increased by 4 pixels | ⚪ No impact (trivial visual adjustment; no measurable performance delta) | ⚪ No impact | ⚪ No impact | ⚪ No impact |
| Bluetooth settings navigation via gamepad | ⚪ No impact | 🟡 Low (input method convenience; negligible resource footprint) | ⚪ No impact | 🟢 Medium (improves couch-gaming UX for controller-only setups; no frame-time benefit) |
| Taskbar fix (invisible search icon in vertical mode) | ⚪ No impact | ⚪ No impact | ⚪ No impact | ⚪ No impact |
| Accessibility improvements in Run dialog (keyboard focus narration) | ⚪ No impact | ⚪ No impact | ⚪ No impact | ⚪ No impact |
| Mongolian Baiti font rendering improvement | ⚪ No impact (shaping engine refinement; font rasterization load unchanged) | ⚪ No impact | ⚪ No impact | ⚪ No impact |
Find and Change Settings
| Setting | Where to find | How to change |
|---|---|---|
| Cloud rebuild | Windows Recovery Environment (WinRE) > Troubleshoot > Cloud rebuild | Boot into WinRE, select Troubleshoot > Cloud rebuild, connect to a wired or Wi-Fi network, verify the target build, edition, and language, confirm the data loss warning, and start the recovery. No USB drive or custom image is required. |
| Default backup and restore for corporate devices | Settings > Accounts > Windows backup | On Microsoft Entra-joined or hybrid joined devices, Windows settings backup is enabled by default. To turn it off, go to Settings > Accounts > Windows backup and disable the option. Administrators can override this with existing policies. |
