"My computer kept crashing and was miserably slow. I couldn't have more than three programs running or it would crash. I tried a bunch of different softwares to try and fix it and Registry Defender was far superior. Since I purchased it, my computer has run 100 x's faster and stopped crashing. I highly recommend this if your computer is slow and not working right."
