What this function does is
- 1.Mounts a WinPE WIM
- 2.Adds the missing Volatile Environment (in Current Environment)
- 3.Saves PackageManagenment and PowerShellGet Modules from PowerShell Gallery in the WIM
- 4.Dismount and Save the WinPE WIM
After modifying the WIM, I can test the changes by creating an ISO (or you can USB, whatever). Works like a champ!
