You may wish to disable some of the Windows 7 features that don’t sit well in a corporate environment such as Games or Media Center.
To do this create a Run Command Line Task Sequence.
Enter a DISM command in the Command Line:
dism.exe /online /disable-feature /featurename:<feature name>
To get a list of features type dism /online /get-features | more in a DOS prompt
To enable a feature use the Dism /online /Enable-Feature /FeatureName:<feature name> command.

OMG! Thank you for this one, I have been trying to deploy it as a package and it kept failing
No problem David glad you have sorted your problem.

Hi ..
the command dism.exe /online /disable-feature /featurename: needs to be set after WINPE or before WINPE boot ?
Either would work I believe. I normally run this in full OS stage.
