That AppData path in your comment isn't on your path (supposedly, anyway), so that's probably not what it's using. Unfortunately, there isn't a which command on Windows either.

If you edit your path and move the C:\Program Files\Java\bin directory to the very beginning of the list and it still prints 1.7.0_09, then somehow you have JDK7u9 in your JDK7u7 folder. If not, browse to all the other directories on your path and open them 1-by-1 until you find the appropriate java file. Fortunately for you, your path is much shorter than mine.

Note that when doing:

> java -version

It may also look for java.bat and other non-exe extensions, so keep an eye out for this while you're searching your path. Try running:

> java.exe -version

That way you know you're looking for an exe file.

One last thing you can try:

> "C:\Program Files\Java\jdk1.7.0_07\bin\java" -version

If this returns 1.7.0_09, then something happened that updated your JDK in-place, which isn't supposed to happen, AFAIK (but I could be wrong).
