To delete junk programs in the system

The program is used to delete system spam and there is a memory leak. Why am I still not clear? I posted the code. Let's see what the problem is.
The problem is that, if I create a loop in winmain and put the two functions that Delete the garbage into the loop for execution, the memory occupied by the program will go up, each cycle occupies about 7 MB of memory, and all the variables used by my program are local variables. Theoretically, when the function ends, the memory space occupied by the variables in the program is automatically released, after testing, the memory is not released. The reason is not found. It is depressing !!!!!
