Apparently, I’ve installed Hamachi a while back, so my friend could play some games with me. Turns out, by going to your Ethernet card options (Just type Ethernet in your Windows 10 search bar, click the first option, then hit “Change card settings” in the menu box), you can turn off the Hamachi network and boom, Netcut does work.
Once again thanks to the Admin for help, a pretty darn flawless customer support.
My ICS is turned off. Never turned it on in the first place. Could it be related to the router itself? Maybe netcut just simply does not work with the TP-LINK routers?
