Thanks for the reply rx7tt, I shall try those shortly. However, now im slightly confused. I was under the impression (from reading various registry tweak related threads) that if you add a HKEY_CURRENT_USER value to the registry using the cmdlines.txt the changes would be mapped to the default user profile. However, the above post are HKEY_LOCAL_MACHINE and a quick check on this computer using regedit shows them to exist here, so have I been misreading these threads? Just trying to get things straight in my mind :/
