You may consider contacting Microsoft* since your question is specifically related to Readyboost.
Thanks for the response. I will post this on a Microsoft community but I was hoping that someone would know what change was made in the registry by the Intel tool box that stops the Readyboost from working. (It was actually quite a challenge to turn back on the "superfetch"....as described above.) Since these changes were made by Intel software, I was hoping someone would be able to tell me how to reverse these changes.
Again, Thanks for any help....
