I am trying to repackage kb900325 for myself because I updated ehres.dll with a modded one... and while I understand how to make a normal 7z switchless, I'm not clear on how to do it with a kb... do I just call the "kb900325\update\update.exe" or does it need switches or is there something else I should be calling via the config.txt?

Can´t you sliptream it with nlite?
Al least with me almost all KB´s i can include them via nlite...
Regards

nevermind...
