+# 2604.1
+
+## What's Changed
+
+### Fluent style
+
+With the release of PowerShell 7.6 finally going to GA, I was able to release the Fluent UI styling refresh. This will bring significant improvement to the look and feel of FFU Builder. Note that you will want to make sure you're running **PowerShell 7.6**, otherwise the listviews for Drivers and Applications will be missing the column headers.
+
+### Build tab reorganization
+
+The build tab sections now have expanders for the settings within. This should help with organization of each setting.
+
+### Home page build and release status
+
+The Home page of FFU Builder will now tell you what build you're on and if there's a new build along with the release notes for the new build. You can also see disk space and hyper-v status, as well as the latest Github repo discussions and a list of resources.
+
+### Fixed an issue with Surface and Lenovo driver downloads
+
+Microsoft changed the Surface driver download support page. FFU Builder now uses the [Microsoft Learn page for Surface driver downloads ](https://learn.microsoft.com/en-us/surface/manage-surface-driver-and-firmware-updates) that's designed for IT Admins. It's an easier table to parse rather than trying to parse the updated support page that FFU Builder used to use.
+
+Fixed an issue where retrieving Lenovo models was failing.
+
+### Removed Capture ISO
+
+FFU Builder no longer relies on booting to WinPE to capture builds done via the VM. Instead, FFU Builder will now just capture the VHDX directly. This improves FFU build times tremendously and reduces the need for the VM Switch. The switch is still necessary for those that want to add internet connectivity during the FFU build process.
+
+### Refresh Windows SKU after fallback SKU selection
+
+Fixed an issue grabbing the correct Windows SKU when the user incorrectly chose a SKU that wasn't in the media and had to later be prompted for an available SKU. In this situation the SKU that was provided earlier was chosen, which caused a variety of issues.
+
+### Removed registry-based FFU file naming
+
+Removed registry-based FFU file naming and now rely on parameters provided at build time and the custom FFU naming template. This will remove the hard coded wait times that had to do with loading/unloading of the registry.
+
+### Added a checkbox to enable network connectivity during VM build
+
+Add a checkbox to enable network connectivity during the VM build. I'm fairly confident that the build process should be able to withstand any sysprep-related issues being connected to the internet. The checkbox is flagged as experimental. Give it a try and let me know if you notice any issues.
+
+### Added UI controls for Device Naming
+
+Device naming now has an expander in the Build tab that will expose a number of new options available. Rather than writing up a whole thing here in the release notes, the UI should be intuitive enough to explain how it works. The docs have also been updated. I spent a lot of time testing the changes with both legacy naming scenarios and if you make changes in the UI. If you see something that doesn't work, open a discussion or issue.
+
+### Fixed Office installation issues on ARM64 VMs
+
+I actually didn't fix anything, but rather removed a restriction that was put in place due to Office requiring internet access to install on ARM64. It seems the PG has fixed the issue requiring internet access and office will now install. However there's a caveat that it will prompt with a compatibility assistant popup. I think we can disable the compatibility assistant service to prevent the pop up from happening in the orchestrator. Will look into this in a future release.
+
+### Auto-generate ComputerName in Unattend.xml
+
+Now you can provide your own Unattend.xml without a ComputerName element and FFU Builder will add it if you've chosen to include a computer name. If there's a ComputerName element already in the file, ApplyFFU.ps1 will find it and modify it as per your naming choices.
+
+### Add custom unattend.xml paths
+
+There's a new expander for Unattend.xml options in the Build tab which includes paths for the x64 and arm64 unattend.xml files. This means that you can have your unattend files in any location instead of in the FFUDevelopment\unattend folder. This should make upgrades easier for those that have custom unattend.xml files and copying new releases would overwrite your customized unattend files.
+
+### Fixed an issue where CUs wouldn't service after the March 31, 2026 OOB update (KB5086672) was installed on your host machine
+
+The KB5086672 CU which is rolled into the April 14, 2026 update (KB5083769) caused an issue with Add-WindowsPackage. Add-WindowsPackage uses the DISM API to service a Windows image. The native dism.exe doesn't have this issue. To keep things consistent, FFU Builder will now use the dism.exe from the installed Windows ADK. While this version of dism might be older than what's on your machine, it should be consistent and not be impacted by future CUs.
+
+# 2603.2
+
+## What's Changed
+
+Highly recommended to upgrade to this release due to potential SecureBoot issues
+
+### Fixes SecureBoot-related boot issues on newly deployed FFUs
+
+Fixes an issue where some devices may not boot after an FFU was applied if the FFU was built from a machine that had been updated to the Windows UEFI CA 2023 SecureBoot certificates.
+
+Sometime at the start of this calendar year (Either January or February), a change was made in Windows to how BCDBoot functioned. If you took a CU from either of these months, BCDBoot will now check to see if the device has the 2011 or 2023 CA certificates. If 2023, the local BCDBoot will use the 2023 signed boot files when creating the System partition and these boot files will be deployed to the target system when the FFU is deployed. If the target machine hasn't updated to the 2023 certificates, boot will fail.
+
+To fix this, FFU Builder now uses the version of BCDBoot from the ADK instead of the locally installed version. The version of BCDBoot from the 10.1.26100.2454 ADK December 2024 version (which is what FFU Builder considers the latest), will provide the boot files signed with the 2011 certs.
+
+The version of [BCDBoot from the 10.1.28000.1 ADK](https://learn.microsoft.com/en-us/windows-hardware/get-started/what-s-new-in-kits-and-tools#bcd-boot) from November 2025 will default to using the 2023 certs as long as the machine supports the 2023 CA. This has been documented since this ADK was released. The behavior of this version of BCDBoot is what we're seeing now in devices that have been recently updated.
+
+I suspect that when 26H2 is released, there will be a new ADK around that time and at that point we'll move to using that version of the ADK, which that version of BCDBoot will default to using the 2023 signed boot files and I suspect WinPE will probably default to doing the same. By then, hopefully, most in-market devices should have the 2023 certificates in UEFI and those that don't will need to get the certs or downgrade their ADK version to use the 2011 signed boot files.
+
+### Fixes working directory handling
+
+Creation and deletion of the dirty.txt marker file now use an explicit path based on $FFUDevelopmentPath, avoiding ambiguity and potential issues with relative paths.

     This module is dedicated to managing user interactions within the FFU Builder UI. It contains the Register-EventHandlers function, which connects UI controls defined in the XAML to their corresponding actions in the PowerShell backend. This includes handling button clicks, text input validation, checkbox state changes, and list view interactions across all tabs, effectively wiring up the application's front-end to its core logic.

 Apps Script Variables are key value pairs that are used to create a hashtable that is passed to the `BuildFFUVM.ps1` script (stored in the `$AppScriptVariables` parameter as a hashtable). At build time, `BuildFFUVM.ps1` will export the `$AppsScriptVariables` hashtable to an `AppsScriptVariables.json` file in the `$OrchestrationPath` folder (`$AppsPath\Orchestration`). You can also manually create your own `AppsScriptVariables.json `file and place it in the `$AppsPath\Orchestration` folder.

 This allows for you to create a dynamic task sequence via a PowerShell script with simple if statements to run apps, commands, etc. This is all driven by your `FFUConfig.json` file. For example, the following `FFUConfig.json` file contains an AppsScriptVariables hashtable of foo and vmwaretools like the screenshot above. If you build servers that require vmware tools, you may set the value to true. However there may be situations where you don't need vmwaretools installed. If that's the case, you set vmwaretools to false. This allows for your `Invoke-AppsScript.ps1` file to stay the same and all you have to do is adjust the variables.

+## Enable VM Networking (Experimental)
+
+Controls whether the build VM is connected to a Hyper-V switch during provisioning.
+
+Leave this off for the default offline build path. Turn it on only if you want to test internet-connected builds and understand there may be Sysprep or capture issues.
 
 ## VM Switch Name
 
 Drop down of detected VM Switches. There's also an **Other** option which allows you to specify a VM Switch Name. The other option is useful in scenarios where the machine you're running the UI from isn't going to be the machine where you plan to build the FFU from.
 
-## VM Host IP Address
-
-IP address of the selected Hyper-V switch that will be used for FFU capture. The UI will auto-detected this based on the VM Switch that was selected.
-
-If `$InstallApps` is set to `$true`, this parameter must be configured.
+This setting is only used when **Enable VM Networking (Experimental)** is turned on. VM-based builds still capture from the host-side VHDX after the VM shuts down, so you only need a switch when the VM requires network connectivity during provisioning.

 After validating Winget status, you'll be able to search winget for applications. The larger the result set, the longer it will take for the list view to be populated. For example, if searching for **win**, the UI might appear to hang while it searches for apps with a name or id of **win** due to 669 results being returned and processed. Instead, if you search for **windows app**, 13 results are returned within a few seconds.

 FFU Builder supports x86, x64, arm64, and x86/x64 (both) for applications in the winget source repository. For apps in the msstore source repository, the architecture cannot be changed. In most cases, x64 will be what you want, however in some cases the combo of x86 and x64 will be necessary. This might be due to runtimes (.NET, Visual C++) where an application is expecting both x86 and x64 runtimes.
