NetCut is free, but you might get more features if you buy the pro version.
Features and Highlights
The installation runs just like any other software.
When you run NetCut, you will see new processes in the Windows Task Manager.

Instead, it launches your surfing app and opens a web page in it.
It also lets you know if there is a new gear making a connection to the web connection.
NetCut lets you manage the connected devices.

The former feature is, unfortunately, not a free user can use.
Locking down your data pipe is another way to keep Wi-Fi leechers at bay.
Only the existing connections are allowed to use the bandwidth.
Its free features are indeed limited but still come in handy for those who need them.
