When did you last use your Office Program ?

[Philopolis]

I want to see when PPT/EXCEL/WORD last used on workstations in a remote
office.
Potential to remove altogether if they not using - is there a file or
registry entry I can look at to see this ?
The Windows Add/Remove doesnt seem to cut it.

Perhaps the last access time shown in Windows Explorer.
