“A perfect choice!”

“After searching for a good system optimizer for a while, I found this software perfectly meet my expectation. It not only cleans registry, but includes other functions such as program uninstall, system optimizer, etc, and they all worked great!”

"Excellent!!"

“I've tried several registry tools and this one is my favorite! It did improve my PC performance and never caused any trouble to me (my PC crashed before using some other registry cleaners). I’m so glad that I finally found one that can be trusted!”

“Beyond expectations!”

“Pros: This performed better than i was expecting and i'm thrilled with the results. For a trial use - you can't beat it! Cons: There are no cons - seriously, and it's a name you can trust.
I love it because it really cleaned up and streamlined my computer I play and download a lot of games and this cleaned up all the junk left behind from incomplete UNinstalls, etc. I especially liked the ‘optimize’ feature.”

“Wonderful stuff!”

“Winaso is really a wonderful piece of software. It never let me down. Compared to other registry cleaners I tried, it is much more safe and does its cleaning jobs decently. I highly recommend this software.”

“I trust it”

“I've been using this for several years, and NEVER had a problem. Trust is very important when deleting registry items! Newer versions are getting quicker, and there are also additional very useful tools. It's free.”

“Easy to Use. Very quick!”

“Brilliant piece of software, very friendly, and easy to use, and extremely quick to run a complete scan of my computer (53700 files) in minutes rather than an hour like others i have tried”

“Best of the bests!”

“Very friendly UI, and works just as it's supposed to. I deleted more than 600 registry items, and my machine is running smoother than it has in quite a while. I've used this utility dozens of times with no problems. Highly recommended”

“THIS IS A MUST URCHASE ITEM!”

“This program manipulated my internet browser and other relevant settings such that my PC now SCREAMS through the internet. Additionally, it thoroughly scanned and, more importantly, SAFELY corrected hundreds of registry errors on my PC that other registry scan/repair programs missed.”

“Excellent product..”

“Scans the most areas for questionable registry issues. Very fast and accurate. Latest version is even better. I’ve used it for 3 or 4 years now. Used to use registry Mechanic, but it seemed to not find as much stuff especially after a program un-installation. After trying Winaso, I’ve not looked back.”

“Praiseworthy Cleaner”

“I am very glad reading so many enthusiastic comments for 'WinASO'. It is one from the best cleaners I tried (over 100 up to now). 'WinASO Registry Optimizer', in my opinion, is one from the 7 top cleaners that form the 'Club of Excellence'.”

“Useful Tools”

“This software found more then 300 errors in my registry and fixed them right away. My computer is much faster now. It really helps removing unnecessary registry in my system. Try it!! you will not be disappointed. I installed this, and 10 minutes later my computer was running like the day I bought it. It was very easy to understand and the scans were easy to customize so that I didn't have to sit through it over and over and over. A registry is a very complicated thing and if you don't know the inner workings of one, don't go messing with them. This program is the "how to" you need without the schooling you should have.”
