Blank path in environment variable causing elevated command prompt to not respond

Question

While attempting to install composer on my Windows2008r2 server, I navigated to System Properties, Environnment Variables, and Edit Path, but when I changed the path the elevated cmd prompt stopped working. So I deleted the path and left it blank. Now the cmd prompt doesnt work, and the environment variable is still blank.

Does anyone know the default path for the system variable?

Answer 1

c:\windows\system32;c:\windows;c:\windows\system32\wbem

Is all that is required.
