Using Performance Monitor counter IDs instead of the counter names

Question

Hello,

As you already may know each Performance Monitor counter has the corresponding ID which you can find in the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009\Counter

So theoretically we can get the counter value by typing

Get-Counter -Counter "\2\10" instead of

Get-Counter -Counter "\System\File Read Operations/sec" - and it does work:

But I don't understand why other counters may not be read by such method:

Get-Counter -Counter "\System\File Read Operations/sec"

What;s wrong with the second query?

Thank you in advance,
Michael
