For those of you who are running Windows Vista on their systems, you should read the following Microsoft KB article, before installing SP1. It is still surprising that folks are running into problems with Zone Alarm, after SP1 is installed, since Microsoft has addressed this problem way back in March, 2008. Yet I still see references be made in the forums concerning the problem. In the KB article it states:

Service Pack 1 for Windows Vista is an important update for Windows Vista. Windows Vista Service Pack 1 (SP1) contains many security, reliability, and feature updates for Windows Vista. A program may experience a loss of functionality after you install Windows Vista SP1. However, most programs will continue to work as expected after you install Windows Vista SP1.

This article lists programs that have been reported to experience a loss of functionality when they are installed on a Windows Vista SP1-based computer.

Notes

•	This article should not be considered a comprehensive list of programs that experience loss of functionality when they run on a Windows Vista SP1-based computer.
•	If you are using a program that appears in this article, you may have to contact the software vendor for more information.

 Take a few minutes to read the article and it may just save you from some heart aches down the road.
