The organiser of the US's biggest tech show has revealed to the BBC that Microsoft is returning to the event.
Microsoft announced it was pulling out of CES in 2012, saying that its "product news milestones" did not align with the January tradeshow.
Although it is not scheduled to host a keynote speech at 2014's event, the firm has booked meeting rooms again.
One analyst said the news reinforced the Las Vegas show's claim to be the year's most important tech event.
Others had previously suggested Microsoft's departure might mark "the beginning of the end" of the show.
A spokesman for Microsoft said he was unable to comment.
