In Windows, If you pressed SHIFT 5 times you will open sticky keys window. I don't use sticky keys so I would like to open CMD instead of sethc.exe for that key combination. If you simply replace sethc.exe with CMD.exe, the opened CMD will not be fully functional and misses some tools. So I would like to change the invoking of sethc itself to CMD in registry or something, how can I do that?
