nircmd | Perform tasks using the nircmd.exe utility | Automation library

What I want the script to do:

I need to rename a .mkv video file created by Handbrake by removing the -1 suffix, which Handbrake adds, then delete the original source video file which has the exact same name (minus the -1), but also potentially a different file extension.

Some caveats:

• I'm using Windows SendTo to pass the source file as an external variable to the script
• The source video file and file directory may contain spaces, ampersands and parentheses
• Source files may be of different extensions such as .mp4, .mkv, .wmv, .mov
• Directory locations of the files are not fixed
• Batch script will not be executed within the same directory as the files
• Use NirCmd's clonefiletime command to copy the original file's time attributes to the new file
• Use NirCmd's moverecyclebin command to move the file to recycle bin rather than using del command

Example and expected behaviour

Haven't been here in years - but - now here.

Background: I got a virus and had to wipe my hard drive and install Windows 10 (latest version). I must say Win 10 has changed since I bought my USB Stick. (Downloaded latest version and installed that using my key.) So everything had to be wiped and now I'm reinstalling everything. I have run into two problems which are similar.

First problem: When I try to run a batch file to modify the registry I get:

I'm making a script in Python 3.7 using the Spyder interpreter that uses the subprocess module to map a remote network drive to computers and then check if a file exists in that drive. For example, I'm mapping the drive on my computer as "S:\" but it's mapped to "C:\" on theirs. It's checking if the file "nircmd.exe" exists on their C:\. When I run my code all I get is:
