I've an interesting issue; I added nircmd.exe to my directory by running it as administrator and going through the prompts, and confirmed it was in the directory by looking in C:\Windows. Yet whenever I try to call nircmd.exe from command line, I am greeted by the same prompt that I encountered prior to adding nircmd.exe to the directory.
I am at a loss on what to do now, as this seems contrary to how nircmd.exe is supposed to function when placed in the directory.
