This program rolls together a few things I already did to fix errors and a whole lot more besides. I'm a computer technician. I fix computers every day. This thing has fixed problems I had otherwise given up on. Now, if a computer has more than one "weird" problem I run this first. More often than not it saves me hours having to hunt down the causes of the strange issues, fixing several things at once. Seriously awesome program with some seriously awesome power under the hood to fix tons of strange and otherwise time-consuming issues. Thanks!
