My mom's laptop was very slow (like her rating would be 3/10), it was slow right after she bought it a few years ago, we were hesitating to bring it to office depot cause they charge $125 and they'd ask you to install their own softwares and all that crap.
so we came to this place and hoping they would fix it without installing anything, my mom's laptop didnt have anything so it was ok for them to do a fresh install, he asked us to come back in an hour and voila! her laptop was back to normal, sure it wasnt that super fast but it was faster than before. i just cant open more than 3 apps at a time otherwise it would lag. the result was our previous windows was corrupted, that was it. and he only charged us $75 to fix it. the man was very nice and accomodating, will definitely come here from now on.
will try it for a couple of months to see how it goes.
