End of Support for XP SP1
Support for Microsoft Windows XP Service Pack 1 (SP1) and Service Pack 1a (SP1a) ends today, October 10, 2006. Microsoft will end support on this date. This also includes security updates for these service packs.
Microsoft is ending support for these products as part of the Microsoft Support Lifecycle Service Pack support policy.
If you still have Windows XP SP1 installed then upgrade to SP2 as soon as possible. More information and how to prepare your computer for the upgrade see: Windows XP Service Pack 2 (SP2).
To determine whether you are running Windows XP SP1, right-click My Computer, and then click Properties. If "Service Pack 1" appears under System, you are running Windows XP SP1. You do not need to install SP1a first, but just install SP2.
