As if you needed another reason to do a clean install of WIndows with any new computer, Samsung's got you covered. It turns out that a piece of the bloatware from the OEM is apparently disabling Windows Update because it interferes with Samsung's own software updater. The one that, as you might infer, keeps its bloatware up to date on Windows desktops and laptops. A Microsoft MVP (community member, not Redmond employee) chatted with a Samsung customer service rep, asking why this was happening and the rep replied that Windows Update will install drivers for all the hardware on a machine that may or may not work. So, it prevents such a thing by keeping Windows Update turned off. Fine if you aren't worried about security updates but love keeping things like Samsung's auto-back-up tools up to date. It's almost like Samsung wasn't paying attention to Lenovo and Superfish earlier this year.
Update: Microsoft and Samsung have issued statements to VentureBeat saying that they were working together to address any possible security risks that may arise from this situation.
