Windows SuperFetch is a technology in Windows Vista and onwards that is often misunderstood. I decided to delve into this technology to see what it is all about, and to dispel some of the myths surrounding this feature.

If SuperFetch is just caching and prefetching, wouldn't 'unloading' it take virtually no time, as the memory need not be swapped out or written to disk? And, I would assume, that any work done by SuperFetch is done with ultra-low priority. So, it seems to me, no matter how you cut it, SuperFetch should not cause the performance degradation you're describing; while not providing any benefit, it shouldn't make things any worse than if SuperFetch didn't run at all...

Are you sure this is being caused by SuperFetch? Could it be there is something else causing the performance to degrade over the day?
