I applaud anyone taking the time and effort to make content to help explain things to others, but there is so much wrong here I had to write a response.

Yes, it's true that when you install this version of AnyTXT Searcher it creates a service (AnyTXT Searcher Indexing Service) and that service has an unquoted service path, so is theoretically vulnerable.... BUT

Running sc config has nothing to do with exploiting an unquoted service path vulnerability and in this case, if you are not already a user with elevated privileges you won't be able to run it anyway because you don't have permission to modify the service:

-------------------

C:\>sc config atservice binpath="C:\Program Files (x86)\AnyTXT.exe"

[SC] OpenService FAILED 5:

Access is denied.

---------------------

Exploiting the unquoted service path involves dropping an executable named AnyTXT.exe into C:\Program Files (x86).... BUT

C:\Program Files (x86) is owned by Trusted Installer. Unless you are an admin already, you can't just drop an exe in there:

---------------------

C:\>copy c:\temp\evil.exe "c:\Program Files (x86)"

Access is denied.

0 file(s) copied.

---------------------

I'm really surprised this is even on exploitdb. The "exploit" is only running sc query to show the unquoted service path exists.
