Alright, I found a solution (because I put myself in the same situation as you by messing up my registry deleting and adding the Path String Value, so I now think your problem was registry related). Go to Control Panel -> User Accounts and Family Safety -> User Accounts -> Change my environment variables. Click New...
Variable Name: Path
Variable Value: %SYSTEMROOT%\System32
Click OK.
Restart your command prompt. Type ipconfig. Fixed?
