Problem:

We see the AC (Activity Center) show usage for eg. "Adobe Standard 9"

(here we should see on the screen the detected last use on 20 march 14h...)

But, no metering policies were activated to track those, worst no data show for this machine into events records:

(here we see on the screen - no metering entries for Adobe, and nothing 20th march 14h...)

We also see there are no recorded “last usage” into the Inventory “Add/Remove” dataclass

As we can see into Add/remove windows, and pretty much not reliable…

See cool explain why must never believe last used or size into ADDRemove, here http://blogs.msdn.com/b/oldnewthing/archive/2004/07/09/178342.aspx

Result

So the reporting this information into Activity Center seems false!

Question

From where does the AC display “last used” information on a Software Product/Component, in this case?

I was thinking using metering events, but seem not the “lonely” source! Except of a Bug, of course!
