It was over two years ago that I shared the tip of using Process Explorer to look under the covers at which SAS processes were running on your Windows environment.
Process Explorer recently received a refresh, and it's worth downloading the new version. (Yes, it's free.)
If you want to know how influential this tool has been, take a look at the built-in Task Manager in Windows 7 or Windows 2008. The Task Manager now has many of the features that previously only an advanced tool like Process Explorer could offer. But in the meantime, Process Explorer (also funded by Microsoft) has advanced even further, so don't deny yourself the super-duper advanced view into your running processes.
