Microsoft Windows XP Service Pack 3 (SP3) is now certified with Oracle Oracle E-Business Suite Releases 11i and 12. 
Simply Business As Usual
For Oracle E-Business Suite users, the base desktop client requirements are the same as for Windows XP Service Pack 2 (SP2). Customers already on WinXP SP2 can move seamlessly to the latest Service Pack 3.
All certified browsers –IE 6, IE7, Firefox — are certified with the E-Business Suite on WinXP SP3. Likewise, all certified Java clients — JInitiator and the native Sun Java Runtime Engine (JRE) plug-in — are also certified to work with the E-Business Suite on WinXP SP3.
