Using the 3GB Switch on Windows 7

I was running a routine under matlab and suddenly I got the infamous "Out of memory error".

So, as usual :p, I googled the problem and found that I needed to use the 3GB Switch on my not-so-fan-of-but must-use Win 7.

what I needed to do (as they say here) is : 

run the command "BCDEdit /set increaseuserva 3072"

Restart

et voilà :D
