Windows has many utilities in the Control Panel.
FWIW, there are many transient faults in RAM, CPU and in supporting chipsets that result in corrupted data. Even alpha particles now have a measurable impact on computing correctness!
No "memory tester" utility will help identify, fix and prevent such corruptions, and the smaller and denser chips become, the greater the likelihood that alpha-particle based collisions will corrupt our data.
I expect additional shielding to be fabricated into the cases enclosing many forms of chip as we progress toward and beyond 22nm manufacturing processes.
