Solved Where does Bukkit pick up the _JAVA_OPTIONS?

This is really really annoying, because I can't play Minecraft without lag (Which I could before).
So, I once gave Java (Jre6) more ram to make my Minecraft go faster.

What I type into the Command Prompt:
set _JAVA_OPTIONS=-Xincgc -Xms2048m -Xmx3096m

I was happy then, everything was good until I started the server and I noticed the server uses as much ram as the client and I only got 4 GB Ram.

Ok, to get to the point: I can't set the options back!

I reset it to -Xmx512m -Xmx1204m. It was reseted, but not the server. Everything Java related uses that amount of ram, but not the server. What I tried to reset Bukkit's ram:
-Reinstall Java 6
-Set it back through the Command Prompt (In many ways)
-Set it back through Windows system config
-Reinstall Bukkit
-Delete everything related to Bukkit
-Craft Bukkit Starter changing:
Echo OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"%ProgramFiles%\Java\jre6\bin\java.exe" -jar craftbukkit-1.2.5-R1.0.jar
_JAVA_OPTIONS=-Xincgc -Xms512m -Xmx1024m
PAUSE

I know there's one way to reinstall Windows, but I don't want to, to much stuff I need to transfer.
So where does Bukkit pick the options up so I can reset it?

Thanks to any help in advance. :3
