Microsoft released cumulative update KB5083810 (Build 26220.8340) for Windows 11, version 25H2 for insiders on the Beta channel.
- Share in Windows. The Windows Share Sheet has become more functional for users with AAD accounts (Azure Active Directory / Microsoft Entra). Right in the share window, you can now find and install suitable applications without going to the Microsoft Store and without interrupting your current task. Previously, this feature was only available to users with personal MSA (Microsoft Account). Now it also works with work and school AAD accounts. Management is entirely up to the user: app recommendations can be turned on or off with a single switch.
- Storage. In recent Insider builds, the Dev Drive creation dialog has been updated: now you can specify the size in gigabytes (GB), not only in megabytes (MB). The same change has been applied to the volume resizing dialog under Settings > System > Storage.
- Task Scheduler. Task Scheduler now saves column width settings in the task list view between sessions.
Known issues are not listed in the official build announcement, however, as with any Insider builds, undocumented errors or unstable performance of third-party applications may occur.
Installation via Windows Update. Go to Settings > Windows Update and click Check for updates. A computer restart is required to complete the installation.
The build is also available for clean installation via ISO images on the Windows Insider website. Please note that this update is intended only for participants of the Windows Insider Program on the Beta channel, not for the general public using the stable version of Windows 11.

Find and Change Settings
| Setting | Where to find | How to change |
|---|---|---|
| Share Sheet App Recommendations | Share window (invoked from any app via Share button) | Open the Windows share sheet from any supported app. If you are signed in with a work or school AAD account, app recommendations will appear directly in the share window. To turn recommendations on or off, use the single toggle switch shown in the share window itself. You can also install recommended apps without leaving the share window or opening the Microsoft Store. |
| Dev Drive Size in Gigabytes | Settings > System > Storage > Advanced storage settings > Disks & volumes | When creating a new Dev Drive, open Settings > System > Storage > Advanced storage settings > Disks & volumes and select Create Dev Drive. In the creation dialog, specify the desired size in gigabytes (GB) instead of megabytes (MB). For an existing volume, select the volume and open the resize dialog to adjust the size in GB. |
| Task Scheduler Column Widths | Task Scheduler > Task Scheduler Library (task list view) | Open Task Scheduler and go to the task list view. Resize any column by dragging its edge. The column width settings are now saved automatically and will be restored the next time you open Task Scheduler. No additional action is required to enable this behavior. |
