I know lots of people have been asking about the best way to get their leaked memory back (yes, sorry Microsoft, but the problem still exists...albiet improved from the first version of the OS that shipped with the 700w). Here's a couple great utilities to help you get your leaked memory back
without a soft reset! http://www.oxios.com/memory/
if you want quick access to the benefits of this app, assign the program to a programmable key (like the side button under the volume controls) - if you do this, you can watch it work by holding down OK to get to the memory management screen, then hold the side button and watch your memory available go up!
hope this helps speed this baby up for some other people!
