Hook folder including generating system hook DLL source file　MyHook folder contains the generated DLL and modify the registry, startup items and other source documents. Generated program can not protect their computer use by others. Note: 1 reserved for system startup program entry for the " Alt+ j"　(remember !!!)　2 the xp system vc6.0 debug the program through the compiler (not tried other systems)　3 part code my computer screen size is based on design (Please change the source).
