BloodySword, thanks for your reply. I have searched long and hard to find a way to stop WEI from turning off SuperFetch Service, to no avail. I posted on the MS Social Forum and the only response I received said that WEI does not turn off the service. I got no response to my query about what did. So I have come to the end of my quest. I will continue to see it SeperFetch Service continues to run or again gets turned off. Thanks, John.
It's really strange, perhaps WEI does not turn Superfetch off, but on if the data storage socre is below a specific value. So this means, when you activate Superfetch, it should stay active.
This is what I might to understand out of the answer from MS SF.
