Let me ask my question in this way?
Do Windows XP use all the 6MB L2 cash?or Using cash is depend on OS or programs?

And I thought you were talking about the high cost of Windows XP and CPUs!

The caches are all transparent to Win XP and OSs in general -- to the OS, main memory + the CPU caches just look like a big single-level linear memory.

In other words, yes.
