Don't you want someone to use a software? Please refer

How can someone else not use your software? Set access permissions? Encrypt a folder? Are there other methods?

The following is a relatively "loss" method ~

Create a new text file in the folder where the main program is located;

Rename the file to "ws2_32.dll ".

Now execute your software to see if it can be used? The system will prompt "the application or dll x: \ XXXXXXX \ WS2_32.dll is an invalid Windows Image. Check your installation disk again ."

Next let's take a look at what ws2_32.dll is ~

Ws2_32-ws2_32.dll-DLL file information

See it ~ When the program starts, it first searches for the DLL in the folder where it is located. If it does not, it searches for the system directory. However, because the program finds a fake file, an error occurs and cannot run ~

This DLL is used for the network. Will it be useful for programs that do not access the network? Try it by yourself ~
