I am looking for a solution to locate which process are running over 64 and which ones on 32 bits on my Windows Seven 64 system, there is a simple windows shell command available to do that???
After some thought, I realized the WMIC method is kind of hokey. A much better way to do this is to use a PowerShell script that looks something like this:
If you copy that in to a PowerShell script, call it process-width.ps1, and run it in PowerShell, it will list out all the 32-bit processes followed by the 64-bit processes.
It does this by checking if a process has wow64.dll loaded as a module in to it's process space. wow64.dll is the Windows 32-bit emulation layer for 64-bit operating systems. It will only be loaded by 32-bit processes, so checking for it is a sure-fire way to know if a process is 32-bit or not.
This should work much better as a long term solution.
Will list out all the processes on the system. You can pass parameters to get which are WMI Win32_Process properties. You can find that list here:
One of those may show whether the process is 64 or 32-bit.
e: There isn't a direct property, but you can do:
If the number returned by MaximumWorkingSetSize is greater than 3096, then it's definitely a 64-bit process. On my machine, 64-bit processes will have a MaximumWorkingSetSize of 32768 (aka 32gb), while 32-bit processes will have a MaximumWorkingSetSize of 1380, which is the adjusted size of my swap file. At any rate, the simple check is:

If you have Visual Studio installed, then you can simply use dumpbin.exe from the Visual Studio Command Prompt to dump the executable headers:
The machine header will be 14C for an x86 binary and 8664 for x64:
