Running Winsat benchmark?

Has anyone tried running the Winsat.exe benchmark? I haven’t had success running it as a task or through psexec. It doesn’t seem to like running under the SYSTEM account without access to the GUI, even when I limit to non-video benchmarks like ‘cpu’ or ‘mem’.

C:\WINDOWS\system32>winsat -v mem
Windows System Assessment Tool
> Command Line 'winsat -v mem'
> DWM not running

I’m not holding out a lot of hope of making this work, but thought I’d check before giving up. Running a benchmark platform-wide and bringing back results in an analysis would be very useful to me.
