you can start by uninstalling programs that wouldnt be running from the ssd. Delete temp and internet files. When you choose an ssd get one with an transfer kit and then you can transfer the OS to the SSD. Then disconnect the hdd and install the hdd and reboot. Once all is working well you can install the hdd and wipe the old OS off and begin using it for your storage drive
but by all means, start making backup or you're going to end up buying yourself a copy of win7 down the road.
Thanks for the reply! I'll definitely bookmark this page and come back for when I get the SSD.
