Many Backup and recovery utilities on Windows allow to create an ISO that is, the majority of cases, based on WinPE (Windows Pre-Install Environment), which is also used in the Recovery Partition hidden in each notebook sold with windows. Windows itself allows to generate an ISO like this. There is some to integrate some of these ISOs with your tool ? In my case, i'm using the 3rd party windows backup tool EasyUS to generate those ISOs).
