Neptune SystemCare 2017 Free is a powerful PC tune up freeware with the ability to registry clean and windows optimize, and upgrading to Premier version will fix slow computers.

Neptune SystemCare 2017 is an advanced PC tune up application. The newly released Neptune SystemCare 2017 Version 2 upgraded for two more impressive features, the System Protection and One-click Optimization Startup. These make Neptune SystemCare 2017 even more powerful, not only being an optimizing tool, but also a security application with real-time system protection.

Once an application attempting to make modification without any permission, System Protection will immediately remind users by pop-ups of taking prompt action to stop it. The protector could identify and stop any process trying to secretly change Windows registry. For example, it could prevent any unwanted new application from adding into the windows startup; it could protect programs from changing user's Internet Explorer home page or the default browser one; and also from any attempt to hijack the executable program. System Protection is appearing on the homepage of Neptune SystemCare 2017 with the red button and could be closed off when not needed.

Startup Manager is another new feature of Neptune SystemCare 2017 Version 2 Startup Manager clearly lists all programs and services of startup. It displays as a new tab under System Tuneup. Under the new tab, users could easily manage all programs and services as they want. By One-click Optimizing, speeding up booting time seems so convenient. Or users could check or uncheck the items manually to keep or cancel ones in the startup.
