It seems these may be monthly updates that Microsoft posts for their mapping software as last month a group of updates were made available for download at around the same time of the month.
See Construction Updates for Microsoft Streets and Trips/MapPoint for that list of updates.
This months updates include:
- Streets and Trips 2008 Construction Update
- Streets and Trips 2006 Construction Update
- MapPoint 2006 and Streets and Trips 2007 Construction Update
- Streets and Trips 2009 and MapPoint 2009 Construction Update
- Streets and Trips 2010 and MapPoint 2010 Construction Update
A monthly update schedule is fairly regular for these types of programs. Anyone use these and want to comment on their usefulness?
Look forward to hearing from you in the comments.
