- Refactored the Get-ODTURL function to fix recent download issues. Also added some better error handling
- Moved the odtsetup.exe download to the FFUDevelopment folder and will clean it up after office has downloaded
- Added Get-Childprocesses function to return child processes of parent process
- Added a new -Wait boolean parameter to Invoke-Process function. This is to control whether Invoke-Process should wait in order to track stdout and stderr output. This is needed for processes that may hang, waiting for user input and there isn't a way to bypass (some Intel drivers provided by Dell leave dialog windows even when running silently)
-Invoke-Process now returns process information (returns $cmd). This allows for process tracking when calling the function.
- Since Invoke-Process now returns the process information, also needed to add Out-Null to the majority of the Invoke-Process references to prevent Invoke-Process from writing to the terminal
- Refactored a lot of the Get-DellDrivers function due to inconsistencies with how driver extraction behaves between client and server devices. For client, /s /e seemed to work fine, but for server it would only extract the driver installer content and other dell related files, rather than the driver files themselves. We have since switched to using /s /drivers= which will extract the driver content. Not all drivers support /drivers= and may output some information to the terminal that looks like help documentation. If a driver doesn't support /drivers, the script falls back to using /s /e to do the extraction. If this doesn't work for you, you can always provide your own drivers that you manually download from Dell's website.
- Updated Malicious Software Removal Tool (MSRT) code to handle Windows Server
- Added some additional logging entries
- Removed verbose output of the Optimize-Volume command
- Fixed an issue where not passing an ISO caused the script to fail
- Cleaned up the KBPath folder at the end of the run
- Changed some minor formatting items
- Removed the "Downloading information GUID" messages when downloading content from the Microsoft Update Catalog while -verbose was specified in the command line
- In Get-KBLink, made a change to just grab the first result returned instead of the entire results page. This removes the need to use a break statement in Save-KB when downloading updates. This fixed an issue with the new 24H2 Checkpoint Cumulative Updates in Win11 and Server 2025.
- Changed Windows MSRT search string for x64 and x86. This was mainly to get x64 to the top of the search results. x86 won't actually download since the code isn't in place for content from the MU Catalog to download x86 content (no idea if anyone actually builds x86 FFUs for Win10 - I hope not)
- Added new variable $installationType which uses $WindowsRelease to determine Server or Client. If $installationType is Server, $WindowsRelease version is used to set $WindowsVersion to the appropriate version (1607, 1809, 21H2)
- Fixed an issue where the recovery partition wouldn't be created on server OSes due to winre.wim being hidden. Never saw this on client OSes even though it also was hidden IIRC.
- Removed verbosity for Optimize-Volume as it was outputting when -verbose was not specified.
- Modified some search strings for .NET CUs when installing on Server OS
- Included SSU for Windows Server 2016 as it's mandatory
- Added some error checking for Server 2019 and 2022 CU installations when CU fails due to lack of SSU. If you run into this error, you're using old media and should use the latest. Always use the latest ISO if you can.
- Add parameter $AllowVHDXCaching
- Adds the ability to cache VHDX files together with their configuration
- This should roughly cut the build time in half as long as there are no new patches released since the last cached VHDX file
- Updated MU Catalog search
- Search now includes searching for Windows Server updates
Has been verified to work for Windows Server 2022 and Windows Server 2025 only.
- Update Get-WindowsVersionInfo
- Server Standard is now called 'Srv_Std'
- Server Datacenter is now called 'Srv_Dtc'
- 17763 is matched as Windows Server 2019
- 20348 is matched as Windows Server 2022
- 26100 is matched as Windows Server 2025
- other versions are matched as $DisplayVersion as a fallback
Please remember to update the Windows Server version of 2025 in case it changes until release.
- Update Get-LatestWindowsKB to support searching for Windows Server updates
- Improve the HTML regex to return a more precise match by using the $WindowsRelease variable for lookbehind based searching
- Fixed an issue with UWP apps downloaded via Winget weren't being fully installed. Added /StubPackageOption:installfull to the dism command
- Fixed an issue with Surface Drivers not downloading
- Check for Prefixes.txt file and copy to the USB drive if it exists
- Perform better validation for PPKG, Unattend, Autopilot json, and drivers
- Comment out the Windows Security Platform update as the file has been removed from the MU Catalog.
