CMD commands not recognized (Fixed!)

Software & Operating Systems Windows
1

Today i had problems with Java and not being able to open or run .Jar files, After a little research i changed the PATH file in environmental variable, Java 32 bit was called CLASSPATH and i had some nvidia file as a variable PATH and i replaced it with java 64 bit. It did fix the problem i was having but then later on if i entered any command into CMD it would say "Is not recognized as an internal or external command, Operable program or batchfile" And i carnt work out why. 

I fear that ive probably broken something. Any help would be great.

Make sure the PATH contains the following:

;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;

Or at least the first two, pointing to the system32 folder and the Windows folder.

yep,you erased the path to all your CMD programs, aka commands.
