- 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.
When using -installapps $false when capturing a FFU, a Critical Process Died BSOD would happen when deploying the FFU and Windows attempted to load.
When capturing the FFU, the registry is loaded to grab the Windows version information to create the FFU file name. After unloading the registry, the FFU is captured. This process can happen too fast on certain hard drives (NVME). A 15 second delay was added after the unloading of the registry to allow for the process to complete before the FFU is captured.
