It will work on anything regardless of how it was created, IF you can obtain a kernel handle to the process with suitable rights. Using the Win32 function to directly create a process is handy because that's what it returns (via the process information structure "out" parameter).

There is a function, OpenProcess, that will give you a handle from the global "process identifier".

Having separate handles and ID's is why Win32 doesn't have zombies.

    I know you can suspend and resume processes not created with the Win32::Process module. I've done it in the past using WMI. I can't see any OpenProcess method with the Win32::Process module, and I get this error if I try ant use it: 
    Your vendor has not defined Win32::Process macro OpenProcess

    Update: it looks like OpenProcess() is a Win32 API and isn't implimented in Win32::Process. So my original statement stands - the Suspend() and Resume() methods will work only on processes created with Win32::Process::Create(). If you want to suspend a process that isn't create with that module, then you'll have to use WMI or the Win32 API.
