By the time U set this super-teaser up it tells U that U have a gazillion MAJOR registry probs, and shows 'em all just 2 put U into panic mode, during install it changes the registry it hasn't even fixed yet (oh yeah baby), then when U want 2 fix 'em all after 6 scans (then it dies) it hurls U into the buy me to fix this mess or your 'puter will crash. Hard pushy sell of a freeware product that is nothing more than a fancy add that is a real pain to scan-disk, defrag and go into H-keys even a pro shouldn't tweak, Leave this junk alone or pay, then pray tell what reg-fixer works on all builds of XP, or God forbid Vista that B Gates won't even use let alone tweak.CAVEAT EMPTOR!!!
