I recently updated my laptop to windows 8 pro edition from windows 7 home premium sp1edition , so far my biggest complaint has been not being able to setup gmail as my default mailto handler like I was used to in windows 7.However after reading this post, there might actually be a way to get this accomplished.. at least with me, I've been trying to get this done by using software I downloaded from the web. So far none of it worked properly. Thanks for trying to help all of us with a solution for this issue.
Update: I followed the instructions given here by user kizo2703 , I did in fact get my gmail account setup / synced . Of course at least for me...the biggest test of all will be to get gmail to work when I click on a mailto: link on a webpage.
