I'm not sure if this should be applied or not. It fixes some warnings in an app I've worked on, and as we simply didn't provide these registry entries before (and Windows always does) I guess very few apps check them, or else we'd have had to provide them before. However, it's possible some defensive coding has been going on, and if these entries are present indicating drive caching has been switched off then some apps may bail. It's impossible to know until we try it I think. I'm concerned mostly about games - I think it's unusual for apps to check this. ChangeLog: Add default registry entries to indicate that drive caching has been switched off.
