Question

Where to check the number of times the computer has been used and when it was used?

Answer 1

Your question is a bit vague but if you want to see the recent activity of a computer with Windows, go to Control Panel, Administrative Tools, Event Viewer and click on the folders displayed. It will give you some time stamps to see when a computer was logged on and off, etc.

Answer 2

I believe you could find this out in your computers event viewer.

If you go to the control panel (assuming you are using windows), then Administrative Tools, there is an Event Viewer that logs certain processes on the PC.
