Bob Muglia was the senior vice president of Microsoft's Server and Tools business division.
On April 4, 2007, Doc Brown was watching the "Visions of the Future" keynote at Microsoft's TechEd conference over the internet. He found the presentation to be disastrous, so he traveled to 1:00 PM, 90 minutes after the keynote had started.
Doc told Bob Muglia that Microsoft's visions of the future had not been great, and then takes him back in an updated DeLorean time machine using a 386 computer to March 9, 2001 and April 12, 2003. Doc demonstrated what he meant, showing him the missteps that Microsoft had made in the past such as Microsoft's vision for the future of integrated storage. He then took him into the future to an alternate timeline where Microsoft's failed visions came true, showing him that the Office Assistant and Microsoft Bob were now in control.
Doc then brought Bob Muglia back to 2007 to let him give his keynote speech, which he altered based on Doc's advice.
