Office 2007 SP1 would be delivered through Windows Update utility starting June 16.

This announcement comes as the company aims to alert the customers at least one month before such an initiative is started.

Microsoft Office 2007 SP1 was released officially around five months ago and is available as a free download from their website.

The company said that the customer response for this update has been good and they are all set to deliver it to remaining users who have yet not updated to the latest version.
