According to a report by AllThingsDigital, before launching into the technical details, Microsoft warmed up the crowd with some dancers and house music.
Unfortunately, the song's lyrics flashed on video screens, including, 'The words MICRO and SOFT don't apply to my penis.'
The audience was not amused, and slammed the software firm on Twitter, The Herald Sun reports.
"For those not here, we had flashing disco lights, bad lyrics about penis, disco beats and dancing azure girls, so cringeworthy," one programmer tweeted.
"Wow #microsoft this music thing is probably the most embarrassing i've ever seen and heard," said another tweeter.
According to the report, Microsoft's head of corporate communications, Frank Shaw, later apologized on the micro blogging site.
"This routine had vulgar language, was inappropriate and was just not ok. We apologize to our customers and partners," Shaw tweeted.
