It is also possible to place it on a removable storage drive and directly run it on any computer. But the most important part about this tool being portable is that there are no changes made to the Windows registry keys.

This software is capable of accessing the high precision event timer in-built into your computer. After starting the utility, you are presented with a small window that includes all the relevant information about the current performance.

Please note, it is necessary to click on the start button to start the timer. You can also stop the monitoring process or reset it.
