Click on the 'Details' button. A checkmark will appear in the box. Click the 'OK' button twice. Setup will install the Resource Meter. There is an ongoing debate concerning the usefulness of Resource Meter.
Some experts tend to think that it's useless and takes up more resources than it's worth.
Many point to the warning that Microsoft presents you with when Resource Meter is first activated, which suggests that the tool may slow your system due to the checking operations it performs. Yet during testing, I kept Resource Meter running constantly and didn't notice any performance hit on my Pentium class computer. You might consider adding it to your StartUp folder, as I did, and keep it activated all the time. Click on the 'Start' button. Highlight 'System Tools'.
