Here is a Powershell script I wrote the other day which exports a list of all dependencies for a specific Task Sequence to a CSV file.

How to run it:

1. Run the script using .\Export-Task_Sequence_Dependencies.ps1 -TSID “Task Sequence Package ID”
2. Open dependencies.csv to find the dependencies for the given Task Sequence.

Please provide any feedback you might have.

You can also find the script in the TechNet Gallery.
