Failed to copy!

@Russ Thank you!

@Russ
nircmd.exe is not there...
I'm not sure which file to download...

Hello, Russ!
I didn't manage to do as you said. What I did was:
Extracted the NirCmd files to c:\tools,
and added the folder c:\tools to my PATH enviroment as you can see in the image below:

But when I run the commands you asked for I get this:
'nircmd' não é reconhecido como um comando interno
ou externo, um programa operável ou um arquivo em lotes.

My PC is in Brazilian Portuguese but translating it would be:
'nircmd' is not recognized as a intern or extern command, an executable or a batch file.

What did I do wrong?
