This morning I made another test, this time with positive outcome. I describe you the procedure as following: 1- Windows SP3 integration over a WinXP without any SP (NLITE 1.48) 2- WMP11 + WMPHotFixes integration (WMP11 Slipstreamer v.1.3.4.2) 3- Hotfixes, IE7 and DX9 integration (NLITE 1.48)==>>(kb892130-enu-KB898461-IE7(original-not-ADDON)-KB951066-KB952287-KB951698-KB950762-KB951376-v2-KB951978-KB951748-KB953839-KB952954-KB951618-KB951072-KB950974-DirectX9.c_Ago2008.cab) 4- KB951072 integration using Microsoft method: KB951072.exe /integrate:D:\WinXp\Sp3\XP.....NB:[D:\WinXp\Sp3\XP]is the directory that contain the 'I386' directory) 5- Drivers integration (DriverPacks BASE 8.05) 6- Option and Tweaks application (NLITE 1.48) 7- Make ISO (UltraISO 9.1.2) B) Finally I think that to resolve the problem has been necessary the Microsoft method integration of KB951072....that is possible, if i don't mistake, with nLite too unselecting 'Direct HotFixes integration' in 'advanced setting' in 'HotFixes & Addons' section.
