Need more information... how are you attempting to run it?  What happens when you do attempt to run it?   what if you right click and "run as administrator"?

If neither work, then additionally also try System File Checker.

Assuming you can open cmd.exe in Safe Mode, run SFC /SCANNOW and allow to complete. Run it again and then restart the computer. Now see if cmd.exe runs in regular mode.

For Safe Mode in Windows 8, you should be able to press F8 fast enough to get in. It may take a couple of tries.

Does it actually run (open a black window) and displays an error message there, or simply nothing happens when you click to open CMD?

In the former case, it might be disabled "by your administrator" / sytem restrictions (note: a malicious software could have done it).

Tell me if it is the case and I'll post more details about how to solve that.

Laptop started to have other problems and therefore decided to reinstall O/S. Thank for your offers of assistance.

Looked like major O/S problem was developing. Sometimes the long way round is the quickest!
