ExperienceIndexOK

ExperienceIndexOK is a handy free tool created by Nenad Hrg that gives you immediate access to your Windows Experience Index ratings. This index evaluates key components like CPU, RAM, graphics, and hard drive, offering a snapshot of your system's overall performance. The software lets you both check existing scores and trigger a recalculation to reflect recent hardware or software changes. Since it's portable—no installation needed—you can run it directly from a USB drive or folder. Whether you're benchmarking after an upgrade, diagnosing slowdowns, or comparing systems, ExperienceIndexOK delivers essential performance insights in seconds.
