Yes Sir! that's been drilled into my "duh!" brain! Sadly, I did NOT do a clean install on my last computer upgrade, letting my tech bud talk me out of it ("think of the time to reinstall everything, man!"). I may end up doing a complete reinstall when moving to win 8 as I know there's a lotta history now sitting on the new ssd... that may speed loading but whats 2 minutes wait for heaven?
