ok dumb question time guys:
i also have 4 instances on my developer machine, for versions 2005 thru 2012.
when selecting the memory counters in Perfmon, i see instances for 2008, 2008R2 and 2012 , which are Standard(default instance) , Developer(named instance) and Developer(named instance) respectively.
i don't see my 2005(named instance) , which i know is an Express version.
Do Installations of Express Editions not have performance counters available to them?
