On July 13, Microsoft will be ending official support for Windows XP
Service Pack 2. After that, users either need to be on Service Pack 3,
or move to Windows 7.

At Renascence IT Consulting, we keep you alerted to changes to your
operating systems and can give you opinions on moving your laptop or
desktop to Windows 7, or is just upgrading to Service Pack 3 enough?
Email us if you have any questions or stuck in this quandary.
