Why don't you just answer the Damn question?, I am wandering around my system as well trying to figure out WHY I am losing over %90 of my Hard disk speed short of MS trying to get me into an SSD drive there must be a way to fix it PROPER.
I was coping files and saw that the Hard disk WAS thrashing in a 'readyboot' directory with 20+ files open doing basically NOTHING short of delaying the copy process.
I would LIKE to Know how to turn it off also!, I DON'T Need to cache a bootstrap on win 7, and I most certianly don't need the copy process to RAM no less to be double-Ramming disk reads/writes without my permission.
I see a dozen replies for Win 7 Issues in all the forums I visit. But No one ANSWERS the questions, don't 'Suggest' a software package to fix something, or the old Boot into SAFE mode and see if it happens, GUESS WHAT it does!!
So DOES Anyone HAVE a way to turn this 'readyboot' off!!!, Lets just say I want to do it for shits & giggles soas no to offend the 'Big Brother' Microsofts planning mechanism.
