Is there a way to cancel sfc /scaow in windows 7?

After launching the sfc /scaow resource checker from a command prompt or a batch file, is there any way to cancel the process or does the process have to be left to complete?

In Windows XP, sfc /cancel would allow this. However it does not appear to be the case in Windows 7.

I have tried tasklist hoping to find the image name and then use taskkill to kill it, but I caot identify the sfc /scaow process from the list.

Can anyone tell me which is the correct process to kill? Or is there another way to cancel the sfc /scaow?
