When you use your computer (at home or in your office), on the Internet, watch videos, download, copy/remove files on your computer, install/uninstall or use software, etc., you always leave sensitive traces :
This makes your computer slower and messier, reduces free available space, and puts your privacy at risk.
With the PrivaZer application, you can very easily clean your computer of your electronic traces. You can free up space on your hard drive and improve your system performance at the same time. 
PrivaZer will scan and analyze your system, finding and deleting unnecessary files such as temporary files, internet cookies, record browsing and more. According to the app's website, 250.000 PCs have been cleaned every month since it was launched in 2012.
Since then the app has been updated regularly. PrivaZer has advanced features to securely erase your highly sensitive data, preventing any possible recovery.

Indeed, it is a very good program, I have been using it for several years.
What you failed to include is that it safely cleans OS***.old too, which is why I use it more,
especially when Windows11 Insider Updates OS, it always leaves a **.old behind !!
