Re: Be accurate Perfectdisk here and how else would a decent defragger work out your most recently used. Yep some reg tweaks are useless and achieve nothing. Thinning XP is a different story. 20 sec smart placement defrags.AV scans under a minute and ghost images under 600 meg which take around 2 mins are some of the benefits of following Bold Fortunes guide on slimming XP. As for the "Ccleaner - cripples" comparison it is completely uncalled for and you should edit "your" bullshite xp myths site.
