Potential Buyer in Dell Deal: Microsoft Microsoft in talks, but no confirmation yet By Evann Gastaldo, Newser Staff Posted Jan 23, 2013 9:07 AM CST 7 comments Comments In this Thursday, Aug. 23, 2012, file photo, a new Microsoft Corp. logo, left, is seen on an exterior wall of a new Microsoft store inside the Prudential Center mall, in Boston. (AP Photo/Steven Senne) (Newser) – Microsoft could soon grab one of the largest ownership interests in Dell, in the computer maker's quest to go private. Dell founder Michael Dell is looking to buy the company back from public stockholders, with the help of a private-equity firm, and sources tell the Wall Street Journal that Microsoft is now in discussions to possibly back the deal. No commitment has yet been made, but Microsoft would probably invest $2 billion; the deal is expected to cost at least $22 billion. Though Microsoft wouldn't be involved in Dell's daily operations, Dell would agree to power most of its products with Windows.
