Beware of that program. I have had great sucess with the Disk Defrag and Registry Defrag through Auslogics. That BoostSpeed application however, caused major issues. It started making files re-appear after they were deleted with locks on them, that could not be undone. As well, it also caused on and off freezing of everything on the PC every 2-3 minutes. I was running 7048 64-Bit at the time. If you feel with your build and if it is 32bit, which I am now running 7057 32bit, that it is running good, let me know what you use and what you dont use in it.
