Apply Windows Feature Updates
OneSite Patch allows you to apply annual Windows feature updates.
With OneSite Patch you have the ability to update your Windows version (i.e., version 24H2, 25H2, or 26H2) with Windows feature updates. Windows feature updates are provided by Microsoft as significant upgrades to the Windows operating system. They provide major versions, such as Windows 11 24H2, that roll up security updates and bug fixes along with feature updates and performance enhancements. Feature updates also include Windows 10 to Windows 11 update options.
You activate which version you want by using an enablement package. The enablement package reduces the need for multiple installations and reboots for the various feature updates. Instead, you have a single package install with a single reboot. However, because a reboot is involved, you should verify your reboot schedules per Business Unit.
Windows 11 is the current major release of Microsoft's workstation operating system. The oldest operating system that can be upgraded is Windows 10 2004 (10.0.19041).
Install Windows 11 feature update
Prerequisites
All devices to be upgraded must meet the Windows 11 System Requirements.
Additional prerequisites depend on the Windows 11 version you want to install. Each device must meet one of the supported starting configurations for that target version.
Windows 11 23H2
Windows 10, version 2004, with the September 2021 cumulative update or a later update installed (OS build 19041.1415 or later); or Windows 11, version 22H2, with the October preview update or a later update installed (OS build 22621.2506 or later).
Windows 11 24H2
Windows 11, version 23H2 or 22H2, with the May 2024 preview update or a later update installed (OS build 22631.3672 or later for 23H2, or 22621.3672 or later for 22H2).
Windows 11 25H2
Windows 11, version 24H2, with the August 2025 preview update or a later update installed (OS build 26100.5074 or later).
Windows 11 26H2
Windows 11, version 25H2 or 24H2, with the September 2026 preview update or a later update installed (OS build 26200.9550 or later for 25H2, or 26100.9550 or later for 24H2).
(Optional) Create a target Business Unit
Creating a target Business Unit is optional because patches are installed only on applicable devices. However, Business Units can help you deploy updates in waves and track devices that may need manual intervention.
To group Windows 11 devices by version, create child Business Units under:
Operating System > Operating System – Windows > Operating System – Windows 11
A Windows 10 Business Unit already exists.
For each Windows 11 child Business Unit, use the OperatingSystemCrossPlatform sensor with the following condition:
22H2 Devices
Version Equals 10.0.22621
23H2 Devices
Version Equals 10.0.22631
24H2 Devices
Version Equals 10.0.26100
25H2 Devices
Version Equals 10.0.26200
26H2 Devices
Version Equals 10.0.26300

Unblock Windows feature updates
The OneSite Patch metadata team will automatically block all Windows 11 feature updates so you can decide which devices receive the update and when. In order to add these patches to a strategy you will need to start by unblocking a single Windows OS Upgrade (24H2) or Enablement Package (23H2, 25H2, or 26H2).
For more information about blocklisting see Flex Controls - Blocklisting.

Select Advanced Settings > Flex Controls > Blocklisting > Blocked Patches.
In version 10.0.971+, you can also view blocked patches from the Home Dashboard by selecting the Blocked Patches (System) link in the Patching Overrides widget.

Patching overrides In the View Blocked Patches pane, search for Windows 11 to view the available feature updates.

View blocked patches Search for the feature update version you wish to install, for example Windows 11 26H2.

Curate blocked patches Click the ellipses (...) next to the patch name and select Unblock.
Unblock only one feature update or enablement package at a time. Windows feature updates do not follow supersedence rules, and unblocking multiple versions can result in installation failures.

Create a Strategy to Deploy
Select Strategies from the left side navigation
Click New Strategy.
Overview
Add a unique Name and Description, e.g. Windows feature update 24H2.
Toggle ON Enable Strategy.
What to Patch
Click Browse next to Include Products and select the Windows 11 OS Upgrade (for 24H2) or Windows 11 Enablement Packages (for 23H2, 25H2, and 26H2).

What to patch Click Preview Targeted Patches to verify which patches will be installed.
Click Next
When to Patch
Click Browse next to Schedule and select a time you wish for this patch strategy to run.
Click Next.
How to Patch
Click + Add Transition > Approval Transition.
Click Browse next to Approver Roles and select which roles you would like to have notified when this strategy runs.
Set the Reminder Interval to a desired time.
Click + Add Deployment Ring.
Click Browse and select the Business Unit(s) you'd like to be targeted.
Click Save and Deploy.
Your strategy will now run on your specified schedule and only update devices where the Windows feature update is applicable.
Monitor deployment and installation
Once the Approval Request has been approved, you can monitor the progress with Flex Control Cycles.
After the installation is completed on the device, the Adaptiva client will capture the restart requirement and display a toast notification based on the User Interaction Settings applied to the device. We recommend that users restart as soon as possible. If you normally allow a long delay before restart, you should apply a shorter User Interaction Setting to the Business Unit(s) that were created.
Soon after the device is upgraded, the Windows 11 OS Upgrade product is no longer applicable, and the device will be removed from the Patch Status dashboard. The image below shows the patch status prior to installation. For the 7-Zip MSI x64 this reports the Installed status, however, the Windows 11 24H2 Upgrade will be removed after installation since it is now the installed OS and the device will report its OS status rather than this as an installed patch.

However, you can see the progress of the installation from the Device Dashboard - Device Activity widget.
Select Asset Management > Devices from the left side navigation.
Click on the device Name from the Device Status widget at the bottom of the dashboard. This will open up the individual device's dashboard.
Under Device Activity, you can view the timeline of events including the installation of the Windows Update Feature.

Troubleshooting
Issue - 25H2 Not Applicable on Device
Windows 11 25H2 requires the device to be running Windows 11 24H2 with the August 2025 preview update or a later update installed (OS build 26100.5074 or later).
Solution
To install Windows 11 25H2, the device must be running Windows 11 24H2 with the August 2025 preview update or a later update installed (OS build 26100.5074 or later).
Open the Run dialog, type
winver, and press Enter.Verify that the device is running Windows 11 24H2.
Verify that the OS build is 26100.5074 or later.
The Update Build Revision (UBR) is the final number in the OS build. For Windows 11 24H2, the UBR must be 5074 or higher to meet this prerequisite.

Issue - device does not show Windows 11 OS Upgrade in Installed Products
In %programfiles%\Adaptiva\AdaptivaClient\logs\componentlogs, review the PatchingAdmin.log and look for a line like the following:
Solution
Check for the existence of the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\CompatMarkers\Review the version subkey:
Version 24H2 — GE24H2
Version 25H2 — GE25H2
Version 26H2 — GE26H2
If there are any items starting with Blocked with a value of 1, the device cannot be upgraded.
Remediate any issues and re-scan.
If the registry key does not exist, open a Command Prompt as Administrator and manually run the following command. This will evaluate the device and create the registry key.
This command should be scheduled to run automatically. Review the following if changes have been made to the default Task Scheduler Library.
Open Task Scheduler.
Expand the Task Scheduler Library | Microsoft | Windows and select Application Experience.
In the details pane, select the Microsoft Compatibility Appraiser task.
Review the Last Run Time and Last Run Result.
If you need help executing this across your estate, please contact Adaptiva Support.
Issue: The device is targeted but did not upgrade.
One possible issue is the lack of disk space. The feature update process will not run unless there is 50GB of free disk space.
In %programfiles%\Adaptiva\AdaptivaClient\logs\componentlogs, review the ContentCache.log and look for a line like the following:
The ### needs to be larger than 52428800000 bytes.
