Generic Task Sequence vs. OS Deployment Task Sequence – Inside the _SMSTSType Variable

When creating ConfigMgr task sequences you learn that ConfigMgr assigns different types to them. This type is available as the _SMSTSType task sequence variable during deployment, and also available in the ConfigMgr database, as the TS_Type column in the vSMS_TaskSequencePackage view. The values are:

  • 1: A generic task sequence
  • 2: An OS deployment task sequence

But what really determines how a Task Sequence gets tagged with 1 or 2? Well, the task sequence will set to type 2 (OSD) if it has any of the following actions:

  • General / Join Domain or Workgroup
  • General / Restart Computer (configured for restarting into “The boot image assigned to this task sequence”)
  • Disks / Format and Partition Disk
  • User State / Request State Store
  • User State / Release State Store
  • Images / Apply Operating System Image
  • Images / Setup Windows and ConfigMgr

Note: At least the Restart Computer action can be configured the right way, and be disabled, the task sequence will stil be flagged as an OSD type task sequence.
