I could not find a script that mounts an official MS Windows 10 ISO, adds .NET 3.5 and patches automatically. So.. I made one myself.
Please share any improvements and run at your own risk!
#=== SCRIPT BEGINS ===
<#
.SYNOPSIS
Mount an ISO, enable and or disable features and patches to WIM and save.
.DESCRIPTION
Mount ISO, copy install.wim, mount the file and enable/disable Windows features and patches, and save the changes.
.NOTES
David Djerf, 2017-10-11 - First version that only adds .NET 3.5
David Djerf, 2017-10-13 - Added automatic mounted drive letter detection, made it possible to add and remove custom Windows features, and patches.
David Djerf, 2017-10-16 - Added support for patchfolders
David Djerf, 2017-12-01 - Added export index to new file
David Djerf, 2017-12-08 - Fixed Verbose message for patches not writing name of patches
David Djerf, 2018-04-03 - Added detection for WIM or ESD install-file.
.PARAMETER ISOfile
Full path to Windows 10 ISO file
.PARAMETER WIMIndex
Index number to modify, eg. 1
You can list the index using the DISM command: dism /get-wiminfo /wimfile:<PATH_TO_WIM>
.PARAMETER NewFileName
Your_new_file.wim
Will default to install_modified.wim if not specified.
.PARAMETER WorkFolder
Folder where the magic happens...
If not specified C:\WorkFolder will be used
.PARAMETER Patches
Full path to windows patches in cab or msu format, multiple files accepted if comma separated.
eg. "c:\patches\KB12345.msu","c:\patches\KB654321.msu"
.PARAMETER Patchfolder
Path to a folder containing windows patches in cab or msu format. All patches will be applied.
eg. c:\patches
.PARAMETER WIMAddFeatures
Add Windows features based on their proper "Featurenames"
.PARAMETER WIMRemoveFeatures
Remove Windows features based on their proper "Featurenames" (get features with Dism /Image:C:\workfolder /Get-Features)
.PARAMETER ExportIndexFile
Will export the define index to a new file, provide the full file path.
.PARAMETER Verbose
Add -Verbose to get information about what step the script is running.
