the optimise settings clash with those of AWC2. the setting of AWC2 I find are far better, that is my only moan with this program.
you need to rescan cleaning ten at a time to clean the pc when you first scan [tip just tick a couple of boxes at a time for rescans its quicker]
after cleaning all future scans are give reasonable readings.
eusing reg cleaning is similar to winaso I use both and do alternate scans each week.
