I think vass has it. He set the path to point to his java folder...

you need to put a ';' between entries in order to add multiple entries. When you deleted your old entry, you deleted the path to all your commands.

set path to

 C:\Windows\System32\;C:\Windows\;C:\Windows\System32\Wbem

then put a ; and add your java path in if you still want it.
