Same comments as regards patch 2/9.

Do we really want to use RegGetValue() here and not RegQueryValueEx()? 
This would need tests at least. (E.g. is a string value null-terminated? 
Does REG_EXPAND_SZ auto-expand?)

Is there a reason why this is a switch and not a simple if-else? 
Moreover, I'd expect we'd want to handle more errors than just 
ERROR_FILE_NOT_FOUND (e.g. ERROR_ACCESS_DENIED). I'd guess the above 
code path should be taken except for ERROR_SUCCESS and ERROR_MORE_DATA.

If you pass RRF_RT_ANY, this shouldn't even happen, should it?
