Problem: Task sequence may not finish successfully or has unpredictable behavior.
Possible Solution: The Install Operating System task sequence step (for LTI) or the Apply Operating System Image task sequence step (for UDI and ZTI) may have been modified after the creation of the task sequence step can lead to unpredictable results. For example, if a task sequence was created to deploy a 32-bit Windows 7 image, and then later the Install Operating System task sequence step or the Apply Operating System Image task sequence step was changed to reference a 64-bit Windows 7 image, the task sequence may not run successfully.
It is recommended that a new task sequence is created to deploy a different operating system image.
