As far as i know WSUS doesnt have any good reporting features (which is something that management wants).
I'm actually a bit surprised by this. WSUS is free of charge & you would think your management would love that. On top of that, this program pretty much runs itself. You setup the initial parameters and off it goes.

I'm with HTRegz on this one. If you need in-depth reporting on top of WSUS, so be it. But mention that 4-letter word (free) and you should be able to get management's attention.
