	[DisplayName("Page Faults/sec"): ToInstance Amended, Description("Page Faults/sec is the rate at which page faults by the threads executing in this process are occurring.  A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. This may not cause the page to be fetched from disk if it is on the standby list and hence already in main memory, or if it is in use by another process with whom the page is shared."): ToInstance Amended] uint32 PageFaultsPersec;
	[DisplayName("Page File Bytes"): ToInstance Amended, Description("Page File Bytes is the current number of bytes that this process has used in the paging file(s). Paging files are used to store pages of memory used by the process that are not contained in other files. Paging files are shared by all processes, and the lack of space in paging files can prevent other processes from allocating memory."): ToInstance Amended] uint64 PageFileBytes;
	[DisplayName("Page File Bytes Peak"): ToInstance Amended, Description("Page File Bytes Peak is the maximum number of bytes this process has used in the paging file(s). Paging files are used to store pages of memory used by the process that are not contained in other files.  Paging files are shared by all processes, and the lack of space in paging files can prevent other processes from allocating memory."): ToInstance Amended] uint64 PageFileBytesPeak;
	[DisplayName("% Privileged Time"): ToInstance Amended, Description("% Privileged Time is the percentage of elapsed time that the process threads spent executing code in privileged mode. When a Windows system service is called, the service will often run in privileged mode to gain access to system-private data. Such data is protected from access by threads executing in user mode. Calls to the system can be explicit or implicit, such as page faults or interrupts. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. Some work done by Windows on behalf of the application might appear in other subsystem processes in addition to the privileged time in the process."): ToInstance Amended] uint64 PercentPrivilegedTime;
	[DisplayName("% Processor Time"): ToInstance Amended, Description("% Processor Time is the percentage of elapsed time that all of process threads used the processor to execution instructions. An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count."): ToInstance Amended] uint64 PercentProcessorTime;
	[DisplayName("% User Time"): ToInstance Amended, Description("% User Time is the percentage of elapsed time that the process threads spent executing code in user mode. Applications, environment subsystems, and integral subsystems execute in user mode. Code executing in user mode cannot damage the integrity of the Windows executive, kernel, and device drivers. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. Some work done by Windows on behalf of the application might appear in other subsystem processes in addition to the privileged time in the process."): ToInstance Amended] uint64 PercentUserTime;
	[DisplayName("Pool Nonpaged Bytes"): ToInstance Amended, Description("Pool Nonpaged Bytes is the size, in bytes, of the nonpaged pool, an area of system memory (physical memory used by the operating system) for objects that cannot be written to disk, but must remain in physical memory as long as they are allocated.  Memory\\\\Pool Nonpaged Bytes is calculated differently than Process\\\\Pool Nonpaged Bytes, so it might not equal Process\\\\Pool Nonpaged Bytes\\\\_Total.  This counter displays the last observed value only; it is not an average."): ToInstance Amended] uint32 PoolNonpagedBytes;
	[DisplayName("Pool Paged Bytes"): ToInstance Amended, Description("Pool Paged Bytes is the size, in bytes, of the paged pool, an area of system memory (physical memory used by the operating system) for objects that can be written to disk when they are not being used.  Memory\\\\Pool Paged Bytes is calculated differently than Process\\\\Pool Paged Bytes, so it might not equal Process\\\\Pool Paged Bytes\\\\_Total. This counter displays the last observed value only; it is not an average."): ToInstance Amended] uint32 PoolPagedBytes;
	[DisplayName("Priority Base"): ToInstance Amended, Description("The current base priority of this process. Threads within a process can raise and lower their own base priority relative to the process' base priority."): ToInstance Amended] uint32 PriorityBase;
	[DisplayName("Private Bytes"): ToInstance Amended, Description("Private Bytes is the current size, in bytes, of memory that this process has allocated that cannot be shared with other processes."): ToInstance Amended] uint64 PrivateBytes;
	[DisplayName("Thread Count"): ToInstance Amended, Description("The number of threads currently active in this process. An instruction is the basic unit of execution in a processor, and a thread is the object that executes instructions. Every running process has at least one thread."): ToInstance Amended] uint32 ThreadCount;
	[DisplayName("Virtual Bytes"): ToInstance Amended, Description("Virtual Bytes is the current size, in bytes, of the virtual address space the process is using. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is finite, and the process can limit its ability to load libraries."): ToInstance Amended] uint64 VirtualBytes;
	[DisplayName("Virtual Bytes Peak"): ToInstance Amended, Description("Virtual Bytes Peak is the maximum size, in bytes, of virtual address space the process has used at any one time. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. However, virtual space is finite, and the process might limit its ability to load libraries."): ToInstance Amended] uint64 VirtualBytesPeak;
	[DisplayName("Working Set"): ToInstance Amended, Description("Working Set is the current size, in bytes, of the Working Set of this process. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use.  When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed they will then be soft-faulted back into the Working Set before leaving main memory."): ToInstance Amended] uint64 WorkingSet;
	[DisplayName("Working Set Peak"): ToInstance Amended, Description("Working Set Peak is the maximum size, in bytes, of the Working Set of this process at any point in time. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed they will then be soft-faulted back into the Working Set before they leave main memory."): ToInstance Amended] uint64 WorkingSetPeak;

WMI is a huge subject, so therefore it is practically impossible to provide a comprehensive example program that covers anything. However, the book �Network programming in .NET� (Buy at Amazon UK) (Buy at Amazon US) covers a much wider scope of WMI, and explains how to leverage it to access the bounty of information held within this vast, yet simple object model.
