Modified Page List Bytes is the amount of physical memory, in bytes, that is assigned to the modified page list. This memory contains cached data and code that is not actively in use by processes, the system and the system cache. This memory needs to be written out before it will be available for allocation to a process or for system use. For a full explanation of the memory manager, refer to MSDN and/or the System Performance and Troubleshooting Guide chapter in the Windows Server 2003 Resource Kit.
