SAN FRANCISCO -- Microsoft will add its popular Outlook email program to more tablets running on a lightweight version of its Windows operating system as part of a free software update later this year.
The Outlook 2013 app will be given to owners of Microsoft's Surface tablet and similar devices running Windows RT. That's a slimmed down version of Windows 8, a radical overhaul of the ubiquitous operating system used on most personal computers.
Microsoft Corp. is preparing to modify Windows 8 in response to consumer complaints about the redesigned system released last October. The Redmond, Wash., company announced the addition of Outlook for Windows RT tablets Wednesday at a computer trade show in Taiwan.
A specific release date still hasn't been set for the upcoming update, called Windows 8.1.
