The link points to the download for 1.6D. we use 2.0.48, which is officially still in Beta(I think), but seems to work better and has a reg fix which speeds up the process by remapping the Registry Hives if a sharing Violation occurs. I can post more details here if people are interested!? we have had mixed success with UPHClean at Caterham, where it appears to work fine on "Admin" machines, but refuses to work properly on the IT Room Clusters (which we suspect to be because students just hold the button to log out by turning the machine off, but have yet to prove this, or have official confirmation from Microsoft that this would be the case!).
hope this helps!
