Refactors the main window layout to use a sidebar navigation model instead of a standard tab control, improving the overall organization of the application.
Introduces support for the Fluent theme (Light, Dark, and System) for users running PowerShell 7.5+ (.NET 9+), gracefully falling back to standard styling for older versions.
Adds a new Settings page that allows users to configure the application theme and access helpful documentation and repository links.
Standardizes margins, font sizes, and layout choices across all forms to closer match Windows design guidelines.
Updates configuration handling to save and restore user theme preferences.
Introduces a new parameter to control BITS download priority across the build system and UI, allowing users to optimize transfer speeds when needed.
The feature adds a priority selector to the UI with four options (Foreground, High, Normal, Low) and propagates the selection through the build script and common modules. Priority can be set via UI, command-line parameter, or environment variable, with Normal as the default.
Updates the BITS transfer retry logic to respect the configured priority instead of hardcoding Normal priority, and fixes minor code formatting inconsistencies.
BuildFFUVM.ps1
- Added parameter definitions that were missing:
- AppListPath - Path to a JSON file containing a list of applications to install using WinGet. Default is $FFUDevelopmentPath\Apps\AppList.json.
- PEDriversFolder - Path to the folder containing drivers to be injected into the WinPE deployment media. Default is $FFUDevelopmentPath\PEDrivers.
- Added two new parameters:
- UpdateLatestMicrocode - This is used for Windows 10/Server. When set to $true, will download and install the latest microcode updates for applicable Windows releases (e.g., Windows Server 2016/2019, Windows 10 LTSC 2016/2019) into the FFU. Default is $false.
- UpdateADK - Added for airgapped scenarios where you've manually updated the ADK and don't need it to continually check. When set to $true, the script will check for and install the latest Windows ADK and WinPE add-on if they are not already installed or up-to-date. Default is $true.
- Reorganized the WindowsSKU validateset to make it easier to read and added in 2016 LTSB releases
- Changed version to 2505.1
- Reorganized the releasetoMapping SKUs to make it easier to read
- Omitted Defender/Edge from reporting KB ID since neither includes it
- Updated Save-KB with some enhancements from the UI branch which will handle KBs that don't have an architecture defined in their file name that will leverage a new function Get-PEArchitecture that can interrogate the file name and determine the correct architecture
- Updated Get-ShortenedWindowsSKU with LTSB/LTSC SKUs
- Updated New-FFUFileName to use $winverinfo.Name for $WindowsRelease for client OSes to which will set $WindowsRelease to using Win10 or Win11. This fixes a bug where you might see 10 or 11 instead of Win10 or Win11 for FFU builds that use only the VHDX (e.g. `-InstallApps $false`. This keeps the naming consistent with FFUs built via VM.
- Updated Get-WindowsVersionInfo to fix an issue with naming LTSC 2019
- Added Get-PEArchitecture function
- Commented out the Windows Security Platform Update code since the URL is dead for the content. This is fixed in the UI branch and will be reintroduced in Dev and Main at a later date when the UI work is complete.
- Created a new variable `$isLTSC`
- Modified and reorganized the search strings for the various .net framework components. LTSC introduced some complexity with handling the various .net releases.
- VHDXCaching will now recurse the KBPath folder when finding downloaded KBs to include in its config file
Sample_default.json
- Added new/missing parameters
- ApplistPath
- UpdateADK
- UpdateLatestMicrocode
CaptureFFU.ps1
- `$WindowsVersion` 2016 and 2019 for LTSC releases
- Changed some SKU spacing to make things more consistent and included Enterprise N LTSC
ApplyFFU.ps1
- Updated version to 2505.1
- Updated parameter definition block to be alphabetized (not to be confused by the param block, which is not alphabetized)
- Added $PEDriversFolder script variable to the param block (for some reason it was missing)
- Added ConfigFile and ExportConfigFile parameters to support json config files
- Changed Version to 2412.1
- Modified vhdxCacheItem class to include $LogicalSectorSizeBytes
- Added new function Get-Parameters to help with new config and export config file functionality
- Fixed Get-MicrosoftDrivers function to not require the HTMLFILE COM object, which isn't available in Windows 11. It seems to be installed with Office, which is what was allowing downloads to work and masked the issue.
- Added long path support to prevent issues with oscdimg creating the Apps.iso.
- Fixed an issue where the $PEDriversFolder variable wasn't being used (instead $FFUDevelopment\PEDrivers was used)
- Created a new function New-FFUFileName - this works in conjunction with the new $CustomFFUNameTemplate. The function was needed to support both scenarios where $InstallApps is either $true or $false.
- Added new function Export-ConfigFile. When passing -ExportConfigFile 'Path\To\ConfigFile.json' the script will generate a parameter dump of all of the configured parameters
- Added driver folder validation to throw an error if spaces are detected in the folder name of the drivers folder (e.g. C:\FFUDevelopment\Drivers\Dell 3190). This is due to an issue with Dell drivers and their inability to handle paths with spaces consistently.
- Added back the Windows Security Platform update which grabs it from the web instead of the Microsoft update catalog
- Fixed an issue where the Drivers folder was being completely deleted instead of its sub-folders
- Removed the Requires -PSEdition Desktop. The script works with both Desktop and Core, so pwsh 7 is fine.
- Created a new config folder to hold config files. A new sample_default.json file is provided to show what the format looks like.
- You can now set the computername in the unattend.xml file whereever you want. Prior it required that the computername was the first component element.
