The Win Cleaner is supposed to make your computer system run like it was new. It's easy to install , you just plug it into your USB drive . It takes a few seconds to start running and gets rid of computer clutter. You get unlimited use of the Win Cleaner for one year, and you can only use it on one computer. You don't have to keep the Won Cleaner plugged in all the time to use it. You can unplug it and it folds up for storage. You just click the icon on your browser instead of plugging in each time to use. It's easy to use and works as well as other cleaners . By no means does it make your computer work like new. I would recommend it if you got it really cheap like I did. I found it for $1 at Dollar Tree store so I thought it was well worth it.
