According to MSDN
...although you use the registry to collect performance data, the
data is not stored in the registry database. Instead, calling the
registry functions with the HKEY_PERFORMANCE_DATA key causes the
system to collect the data from the appropriate system object
To obtain performance data from the local system, use the
RegQueryValueEx function, with the HKEY_PERFORMANCE_DATA key.
The first call opens the key; you do not need to explicitly open
the key first. However, be sure to use the RegCloseKey function
to close the handle to the key when you are finished obtaining
This tells me that reading from HKEY_PERFORMANCE_DATA never returns EOF,
so that you have to terminate it explicitly from the outside. So your
behavior sounds absolutely normal.

If the key is present, it'll be in /proc/registry. FWIW, the MSDN web
page above doesn't mention any restrictions on the systems that this key
is present on.
