如果您不介意自己编写简短的源代码，则可以使用下面的代码。您需要将其编译为Windows控制台应用程序。例如，在Visual C ++命令提示符下，您可以使用
cl /D_WIN32_WINNT=0x0401 remap_capslock.cpp /EHsc /link user32.lib
密钥重新映射在应用程序运行时起作用。无需重新启动，注销/登录等。如果需要重新映射才能以管理员身份运行的应用程序正常工作，则还需要以管理员身份运行重新映射器应用程序。到目前为止已经使用了几天（在Windows 10上），到目前为止还不错。
// The app allows to remap CapsLock key to Esc (if pressed separately) or to Ctrl (if pressed with other keys).
// This may be useful for Vim.
// To compile from Visual C++ command prompt:
// cl /D_WIN32_WINNT=0x0401 remap_capslock.cpp /EHsc /link user32.lib
// Original source (which supported only Caps-Ctrl remapping): /superuser//a/1490007/22750
