Short answer: .msc
is not an executable file type.
Long answer:
.msc
is what's called a snap-in for the Microsoft Management Console.
From the command prompt or even from Start -> Run (win + R), running services.msc
tells the operating system Hey, run this file with whatever program is associated with .msc
files.
That program in particular is called mmc.exe, and even when run services.msc
from the command prompt and look in the Task Manager, you'll see the window actually belongs to services.exe.
Try to start either mmc.exe services.msc
or cmd.exe /C services.msc
instead.
