Onfolio was acquired by Microsoft in 2006.[14] At Microsoft, Allaire created a blog publishing product called Windows Live Writer, initially released in 2007.[15][16] Windows Live Writer was distributed by Microsoft as part of Windows Essentials, until it was discontinued in 2015 and forked into an open-source version called Open Live Writer.[17]
