Notes

• The 32-bit initial PoC was written and tested by myself, on Windows 10 with Office Professional Plus 2016, version 1902.

• The 64-bit version is a contribution brought by @py7hagoras.

• The size of the original command line stored in originalCli needs to be greater than the size of the real one stored in cmdStr
