Disk Counters in Windows Server 2012 Task Manager

I was teaching a Windows Server 2012 Workshop in Oklahoma City this week and a student pointed out that the disk counters can be loaded into task manager in the same way as they can be in Windows 8. Here is the Windows 8 view, for instance:
image_2_3F8A98AC

And here is the default view for Windows Server 2012 (no disk counters):
image_4_3F8A98AC

But if you type in diskperf –Y it will add them:
diskperf-y_thumb_3F8A98AC

This is the result:
diskperf-y-2_3F8A98AC

Thanks to Adam Gaglione (who in turn thanks Sean Shannon) from Dell for the tip!!
