Hi, What error message did you receive when you open CMD? Did it works before? Please remove chrome, try to open the cmd.exe on C:\Windows\System32, if still not work, you can copy cmd.exe file from another machine. If issue persists, some components may corrupted, you can perform an in-place upgrade to fix the issue: http://support.microsoft.com/kb/2255099 Hope that helps.
