Bartpe or PEBuilder enviroments are bloody handy.. Just getting the tools you want to work is the only hurdle.. The current disk I have in use is configured with a remote registry tool, adaware (v6 not se) , McAfee commandline AV, and Mcafee Stinger.. various passsword recovery tools (testing - but who needs it most machine have a blank admin pass anyhow)

With any of these tools you need to know what your doing.. don't trust them 100%.. but as mentioned earlier the live cd approach get around a get number of obsticals when virii or adware hunting..

Will have a good look at your idea chsh..

cheers
