Michigan has opened the 2012-13 season with nine consecutive wins.
After being hired in 2007, Beilein went 46-53 in his first three seasons at Michigan before turning it around and going 54-24 since the beginning of the 2010-11 season.
Beilein told Nick Baumgardner of Mlive.com that he hopes "the next 100 at Michigan are easier than the first 100" as he categorized his first three years at Michigan as transitional.
Beilein's 100th win improved Michigan to 9-0 this season. The Wolverines are currently ranked No. 3 in the country, which is the highest they have been ranked since Beilein took over in 2007.
For his career, Beilein is 651-395 and has posted winning records in 29 of 34 seasons as a head coach. Beilein is the only active coach in the collegiate ranks to record a 20-win season at four different levels - junior college, NAIA, NCAA Division II and NCAA Division I.
