Once this build is working, i am going to put the how-to on Spiceworks and give you as much credit as i can, i can really seeing this be a very useful admin tool.
Make sure you give the credit to ChrisR and the team of experts who developed Win7PE_SE (link to project page in tut); Like I say in the tutorial, it's not my project; I just customize it to my liking, especially portable apps compatibility with other projects listed.
the only thing i would really like to get working is the BGinfo, but you said you use a portable? which one?
It's part of SiSuite2010 in the last batch of ppApps; I'll update it and post a new download link. Look in the tutorial under portable app's section.
Still working on the GimageX script, it's working fine but I need to test 64 bit part; also I'm working on adding a DISM GUI or at least context menu options... little more time
