Another windows update has disabled my Optiarc DVD/RW ad-5530a. I used Monaco's fix with the registry code and it was fine until the update for 2/23/10 (today). Since I have the code lines I'll have my friend work on it again. Is there anything I can do to keep this from happening again? Anyone have an idea which update I should not be downloading? It seems to be random since I've gone through several updates without this happening a 2nd time...until now. I'm running Vista Home Basic. Thanks.
