Smart Defrag still shows the history of all the defrags since back in August. I even installed the version 2.6 (Final) in a different location on the drive, rather than in the IOBit file in Program Files (x86)! I now have version 2.6 (Final) and have accomplished a clean install and using ASC 5 Pro to clear the register of residue from the older install.
Back on September 26th, I posted concerning a few quirks in Smart Defrag 2.5.
