Application that automatically tracks amount of active time spent at the computer
We just equiped a school with new computers, runnning Windows 7. We'd like to know how much the computers are used.
We don't need to know who is connected, which program is launched, etc. Just the cumulative time of use (or better, active use, with someone using it, not just computer idle).
The goal is to understand where/when more computers are needed. The principal thinks if teachers know the time is recorded, this will modify the usage significantly (not for everyone, not voluntarily). So we search something not too loud. This don't have to be hidden, just sober.
I found some softwares to do that but they cost a lot for us (we have 60 computers and no more money), and we don't need most of their features, because they do lots of things.
Anyone know how to track this usage time ?
