This program is an implementation of some commands in the local Windows, which is very easy, just use Runtime.Getruntime (). EXEC, the calls in the program can be found in System32, for the program installed by the user, only need to get The mounting path of the program, then calls the above method, the principle is the same. (This program is not implemented, don't want to write, the principle is the same)
