- Client OSes will now use CatalogIndexPC.xml to identify which ProductLine_SystemID.xml to use to identify which drivers to download. This is inline with how DCU works.
- In the UI, Dell Model names now show the full product line, model number, and system ID in the model column.
- There are many more models now shown due to breaking each model out by systemID (one model will have many systemIDs).
- Downloads per model should be much smaller as prior code was downloading drivers for models that Dell had reused their model number (e.g. Precision/Inspiron/Latitude/Vostro 3520 would result in a very large driver download)
- Dell driver downloads are best effort based on the data from the XML files. In some cases the Dell support website may show a newer driver than what is downloaded. This is rare, but in testing I've seen one or two drivers per model where the XML doesn't have what's listed on Dell's website. Again, rare, but not unexpected.
Changes the default Windows version from 24H2 to 25H2 across the FFU development tool to reflect the latest Windows 11 release.
Adds dynamic products.cab download functionality for Windows 11 using Windows Update service API instead of static MCT links. This is due to a change in how the MCT pulls the products.cab file.
- Sorts top-level config keys before serialization for deterministic files and cleaner diffs.
- Increases JSON depth to 10 to retain nested settings.
- Writes JSON as UTF-8 via Set-Content for consistent encoding.
- Applies across config export and UI save flows.
- Enables selecting multiple existing FFU images to include on the deployment USB for easier distribution and testing.
- Adds a UI option with selectable, sortable list from the capture folder, refresh support, and persisted selections.
- Validates that selections exist when the option is enabled to prevent empty runs.
- Supports unattended/CLI flows by prompting early or accepting a preselected list for USB creation; deduplicates and logs chosen files.
- Always includes the just-built (or latest available) FFU as a base.
- Improves no-FFU handling and streamlines multi-FFU selection workflow.
Adds per-app control for additional accepted exit codes and ignoring non‑zero exit codes to improve handling of installers with nonstandard returns.
Exposes editable fields in the app list UI, persists them across search defaults, import/export, and pre-download save, and applies overrides during app resolution to honor configured behavior.
Applies name sanitization when persisting the app list and when building/checking Win32 and Store download directories.
Prevents invalid characters in folder names, aligns persisted names with on-disk structure, and improves detection of existing content to avoid redundant downloads and errors.
Adds persistence of AdditionalExitCodes and IgnoreNonZeroExitCodes when exporting the UI list to prevent losing custom exit handling settings and maintain parity with the primary save routine.
Introduces a new common function, `ConvertTo-SafeName`, to sanitize strings by removing characters that are invalid in Windows file paths.
This function is now used consistently when creating directory and file names for drivers (Dell, HP, Lenovo, Microsoft) and applications to prevent path-related errors. It replaces several ad-hoc sanitization methods with a single, more robust implementation.
Extracts the logic for importing supplemental assets (Winget, BYO, Drivers) into a new reusable function. This function is now called by both the manual and automatic configuration loaders, reducing code duplication.
Enhances the manual configuration loading process with more robust error handling. It now provides specific user-facing error messages for file read failures, empty files, and invalid JSON, improving the user experience when loading a malformed configuration.
When loading a configuration, if optional supplemental files like AppList.json are referenced but not found, an informational message is now displayed to the user instead of failing silently.
Implements a deferred cleanup mechanism for driver source folders when they are compressed to a WIM and also used for WinPE.
When drivers are compressed, the original source folders are now preserved if they are also needed for WinPE driver injection. A marker file is created in these preserved folders.
A new cleanup step is added after the WinPE media creation to remove these preserved folders, ensuring they are available when needed but not left behind permanently.
Introduces a new feature, `UseDriversAsPEDrivers`, that allows WinPE drivers to be sourced directly from the main driver repository.
When enabled, the script scans all available drivers, parses their INF files, and copies only the essential driver types (e.g., storage, mouse, keyboard, touchpad, system devices) needed for WinPE. This eliminates the need to maintain a separate, manually curated `PEDrivers` folder.
The UI is updated with a new checkbox that becomes visible when "Copy PE Drivers" is selected, making this a sub-option. Parameter validation is also adjusted to support this new workflow.
Introduces a "Restore Defaults" feature in the UI to reset the environment. This action removes generated configuration files, ISOs, downloaded apps, updates, drivers, and FFUs.
The post-build cleanup logic is refactored from the main build script into a new common function. This new function is used by both the standard build process and the new restore defaults feature, promoting code reuse and simplifying maintenance.
Updates the visibility of UI panels for Winget and drivers when a previous environment is automatically loaded.
This ensures that if Winget apps or driver models are present, their corresponding UI sections are made visible. Additionally, it updates the "select all" checkbox state for Winget results and attempts to pre-select the hardware make for loaded drivers.
Implements a new feature to automatically load the previously saved environment when the UI is launched.
This improves user experience by restoring the last saved configuration, including selected applications and drivers, eliminating the need to manually reload them on each run.
The process loads the main `FFUConfig.json` and then proceeds to load associated Winget, BYO App, and Driver lists if they are defined. UI elements and checkboxes are updated accordingly to reflect the loaded state.
- Changed the default disk size parameter from 30GB to 50GB in BuildFFUVM.ps1 and FFUUI.Core.psm1 to accommodate larger virtual machines.
- Updated tooltip and default value in the UI XAML file to reflect the new disk size.
Clarifies the distinction between the application architecture to be downloaded and the target Windows architecture for installer pruning.
Renames the `SelectedWindowsArch` parameter to `WindowsArch` and introduces a new `ApplicationArch` parameter. This makes the download and subsequent installer selection logic more explicit and easier to understand, especially for MS Store apps where multiple installers might be available.
Refines the post-download cleanup process for applications with multiple installers.
When multiple installers are downloaded for an application, this change introduces logic to select the most appropriate one based on the target Windows architecture. It prioritizes universal installers first, then architecture-specific installers, before falling back to the previous method of selecting the newest file by signature date.
This ensures a more accurate installer is chosen, especially when Winget provides multiple architecture options for a single package.
Improves the reliability of WinGet app processing by making several key changes.
The build process now deletes the `WinGetWin32Apps.json` file before each run to ensure it is always freshly generated.
The UI no longer relies on `WinGetWin32Apps.json` to detect previously downloaded content. Instead, it checks directly for the application's content on disk, preventing unnecessary re-downloads.
This change also introduces a feature allowing users to override the default silent install commands for Win32 apps. By specifying `CommandLine` or `Arguments` properties in `AppList.json`, these values will be used to update the corresponding entries in `WinGetWin32Apps.json` during the build process.
Eliminates the read-only field and derives the features list directly from the checked items, producing a sorted semicolon string when collecting config. Avoids duplicated state, prevents desynchronization between UI elements, and yields deterministic ordering for persistence.
- Creates a new parameter [bool]InjectUnattend
- This will take the FFUDevelopment\Unattend\unattend_[arch].xml file and copy it to the FFUDevelopment\Apps\Unattend and rename the file to unattend.xml.
- This is useful for situations where you don't use the USB drive for deploying the FFU but still have Unattend-related customizations that you want to apply.
- Implemented Select-VMSwitchFromConfig function to handle VM switch selection based on configuration.
- Enhanced Register-EventHandlers to persist custom VM switch name and IP address when 'Other' is selected.
- Improved user experience by ensuring relevant fields are populated correctly based on user input and configuration settings.
- Introduced a new parameter `MaxUSBDrives` to control the maximum number of USB drives that can be built in parallel, with a default value of 5.
- Updated UI to include a textbox for setting `MaxUSBDrives`.
- Implemented validation to ensure the value is a non-negative integer.
- Adjusted the deployment function to respect the `MaxUSBDrives` limit during USB drive creation.
Introduces multi-selection capabilities to the "Bring Your Own" applications list, allowing users to select and remove multiple applications at once.
This change also adds the ability to edit an existing application's details directly from the UI. The application list view is now dynamically generated to support these new features, including selectable rows.
Key changes:
- Adds "Edit Application" and "Remove Selected" buttons.
- Enables/disables action buttons based on the number of selected items.
- Modifies the "Add Application" form to function as an "Update" form when editing.
- Implements selection via mouse click, checkboxes, and the spacebar.
This ensures the main application installation feature remains active when any of its dependent options are chosen, creating a more consistent user experience.
Updates UI logic to automatically select the main 'Install Apps' option whenever the 'Bring Your Own Apps' option is selected.
This ensures the parent category is always active when a user opts to bring their own applications, preventing an inconsistent UI state. The logic is applied both when updating panel visibility and when restoring checkbox states.
Introduces a new feature allowing application installations to succeed regardless of their exit code. This is useful for installers that may return non-standard exit codes which should be treated as successful.
Changes include:
- A new checkbox in the UI to enable this option for an application.
- Updates to the application installation script to handle the new setting.
- Modifications to save and load this setting in the application list.
Refactors the process invocation logic to use the .NET Process class for more robust output stream handling and to avoid temporary files.
Introduces a feature allowing users to specify additional success exit codes for applications in the UI. These codes are now considered successful during the installation process.
Adds a 'PAUSE' command to halt script execution and wait for user input.
Adds a new function to programmatically retrieve the required authentication token for the Lenovo PSREF API. This change is necessary as Lenovo is now restricting API access without a JavaScript-generated token.
The new function launches a headless browser instance, uses the DevTools protocol to extract the token from local storage, and then terminates the browser. This ensures continued access to the comprehensive model data available through the PSREF API, which is not fully present in other catalogs.
The User-Agent string has also been updated.
Refactors the application download logic to correctly handle packages from the 'msstore' source, which does not support architecture specification.
- The download process no longer passes an architecture parameter for msstore apps.
- The architecture selection dropdown in the UI is now disabled for msstore apps to prevent invalid configurations.
- Imported or searched msstore apps will display 'NA' for their architecture.
Refactors the Store app installation script to be significantly more robust and intelligent. The new implementation automatically resolves application dependencies instead of relying on a simple folder structure.
Key improvements include:
- Pre-scans all application folders to create a central catalog of available dependencies.
- Parses the `AppxManifest.xml` from each main app package (including from within bundles) to determine its true dependencies.
- Resolves the required dependencies by finding the best available package from the catalog that meets version and OS architecture requirements.
- Adds support for extracting zipped dependency packages.
- Improves temporary file management and logging.
Refactors the Winget search functionality to enhance performance and provide a better user experience.
- Updates the UI to show a wait cursor, disable the search button, and display a status message during the search operation.
- Improves the post-search status message to differentiate between new and total applications found.
- Utilizes `ForEach-Object -Parallel` to speed up the processing of search results on multi-core systems.
Removes the log message that is generated when auto-scrolling is enabled. This reduces log spam, as this can be a frequent event.
The message for when a user manually disables auto-scrolling is retained.
Improves the reliability and clarity of the application download process.
- Introduces specific error codes for download failures, such as publisher restrictions from the Microsoft Store.
- Blocks downloading the Company Portal app from the `winget` source due to packaging issues and provides a user-friendly message.
- Refines status messages in the UI for better user feedback.
- Installs the WinGet PowerShell module for all users to prevent context-related issues.
Improves the pre-download check to correctly identify existing multi-architecture applications by looking for both x86 and x64 subfolders.
This prevents unnecessary re-downloads of apps that have separate builds for each architecture. The logic is also consolidated to remove a redundant code block.
Introduces the ability to specify and download multiple architectures for a single application.
- Adds an "Architecture" dropdown column to the Winget UI, allowing users to select the desired architecture(s) for each app (e.g., x86, x64, arm64, or 'x86 x64').
- Updates the download logic to process each specified architecture, creating separate subfolders for multi-architecture Win32 apps.
- Modifies the app list format to save and load the selected architecture for each application.
- Improves the download process by checking if an application has already been downloaded before attempting a new download.
Removes the use of global variables for paths and architecture settings. Instead, these values are now passed explicitly as parameters to the relevant functions.
This change improves code clarity, reduces the risk of side effects, and makes the functions more modular and easier to test.
Adds standard PowerShell comment-based help blocks (synopsis and description) to all UI and common library script modules (`.psm1`) and the main UI entry point script (`.ps1`).
This improves maintainability and discoverability by documenting the purpose of each script file. Also removes various redundant or commented-out code blocks.
Adds a "Threads" setting to the UI, allowing users to control the throttle limit for parallel tasks like driver and application processing.
This introduces a new textbox in the build options and updates the parallel processing function to use this configurable value instead of a hardcoded one.
Input validation is also added to ensure the threads value is a valid integer and is at least 1. The new setting is integrated into the configuration save/load functionality.
Adds a validation check to ensure application names are unique.
If a user attempts to add an application with a name that already exists, a warning message is displayed, and the operation is cancelled.
Prevents stale, intermediate status messages from overwriting the final status of a completed task in the UI.
A set of completed task identifiers is now maintained. Any incoming intermediate status updates for tasks that are already marked as complete are ignored.
The job completion logic is also refactored for better robustness and clarity across different job-end states (failed, completed with data, completed without data).
Improves the "Copy BYO Apps" functionality by centralizing the `UserAppList.json` update process. The application list is now saved once from the UI before starting the copy, rather than individually within each background task.
Adds a confirmation prompt that warns the user if any application folders already exist in the destination, allowing them to choose whether to overwrite them. The copy logic is updated to remove existing folders before copying to ensure a clean state.
Enhances the orchestrator script to skip application installation steps if no corresponding app lists or files are present. This prevents unnecessary script executions and cleans up the output log.
Makes the 'Arguments' field optional when adding a 'Bring Your Own' application, simplifying the process for apps without arguments.
Ensures the 'Priority' field for applications is consistently saved as an integer to improve data integrity.
Implements the click handler for the browse button associated with the Office configuration XML file path.
This change enables users to select the configuration file via a file dialog, automatically populating the path into the text field and improving usability.
Refines the logic for setting the Windows Release from a saved configuration to handle ambiguous values.
When a release value like '2019' exists for both Server and LTSC editions, the UI could select the wrong item. The logic now inspects the `WindowsSKU` config value to differentiate between them, correctly selecting the LTSC or non-LTSC release.
Improves the user experience in the monitor tab by making the log output autoscroll conditional.
Autoscrolling is now disabled when the user selects a log entry other than the last one, allowing them to inspect previous output without interruption. Selecting the last item in the list re-enables autoscrolling.
