Sure, no problem... also, you can list more than the process name. I
like to show the PID and the executablepath, etc. Here are other process
items you might like to examine:

class Win32_Process : CIM_Process
{
  string Caption;
  string CommandLine;
  string CreationClassName;
  datetime CreationDate;
  string CSCreationClassName;
  string CSName;
  string Description;
  string ExecutablePath;
  uint16 ExecutionState;
  string Handle;
  uint32 HandleCount;
  datetime InstallDate;
  uint64 KernelModeTime;
  uint32 MaximumWorkingSetSize;
  uint32 MinimumWorkingSetSize;
  string Name;
  string OSCreationClassName;
  string OSName;
  uint64 OtherOperationCount;
  uint64 OtherTransferCount;
  uint32 PageFaults;
  uint32 PageFileUsage;
  uint32 ParentProcessId;
  uint32 PeakPageFileUsage;
  uint64 PeakVirtualSize;
  uint32 PeakWorkingSetSize;
  uint32 Priority;
  uint64 PrivatePageCount;
  uint32 ProcessId;
  uint32 QuotaNonPagedPoolUsage;
  uint32 QuotaPagedPoolUsage;
  uint32 QuotaPeakNonPagedPoolUsage;
  uint32 QuotaPeakPagedPoolUsage;
  uint64 ReadOperationCount;
  uint64 ReadTransferCount;
  uint32 SessionId;
  string Status;
  datetime TerminationDate;
  uint32 ThreadCount;
  uint64 UserModeTime;
  uint64 VirtualSize;
  string WindowsVersion;
  uint64 WorkingSetSize;
  uint64 WriteOperationCount;
  uint64 WriteTransferCount;
};
