Most of what IEAK does is put in place IE policies.. and configure the internet control panel, and default shortcuts...
You possibly could undo the reg mods that ieak did, but that could be more difficult than just redeploying IE6
look in
HKEY_CURRENT_USER\Software\Policies\Microsoft
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer
(and a few others)
