Cmd commands don't work

I have a new laptop (Windows 10) and it doesn't execute cmd commands. I don't even get an error message, just nothing happens.

I already read other posts and changed my path. However, it didn't work. Does anybody know how to fix this?
 
If you can get to a Command Prompt window

enter ECHO %PATH%

to see your path -- it MUST contain
C:\Windows\SYSTEM32;C:\Windows;C:\Windows\SYSTEM32\WBEM;C:\Windows\SYSTEM32\WINDOWSPOWERSHELL\V1.0;C:\PROGRAM FILES (X86)\COMMON FILES\MICROSOFT SHARED\WINDOWS LIVE
