I was on the phone with MS because my Adobe Premiere Elements program was misbehaving, even after several "Geek squad tuneups" and several reinstalls. My Explorer 2 program was crashing all the time and the developer couldn't figure out why. MS suggested that I reinstall my OS, they left me after the process was initiated. But when it was done I had new problems and called them back. They told me the person I spoke with made a mistake and should have transferred me to a SB specialist. They transferred me to one and they ran a bunch of processes and fixed the problem. That leads me to wonder about just how unique the SB is, that MS needed to transfer me to a specialist. Does that mean that the next time I need to reinstall the OS shouldn't rely on the MS process for doing so? Are there any other situations where I should no rely on MS support to address and should I always seek SB support only because of it's UEFI BIOS or other unique configuration?
