Default Unrooting Galaxy Tab 2 7.0

Is it possible to unroot without flashing CWM or anything?

I'm tempted to follow http://forum.xda-developers.com/show....php?t=1791193 on rooting, which allows me to root by running a .bat file and without flashing stuff, but I can't seem to find anything on unrooting without flashing stock firmware etc.

Any help would be appreciated
