To whom it may concern, I will try to answer the quoted paragraph, however I have basically two questions. This is how far I made: I got some files from a search I did in my PC, using a KB...X file and the search gave many files I have copied in a folder, and also typing the names from the Start>Control panel>Add/Remove programs Windows actualizations list. I guess there´s an error or something wrong with this procedure, because some "tutorials" I read said there were .txt files to copy in nLite for actualizations integration (http://www.letheonline.net/manualnlite.htm), and I found many different files formats for actualization found in the Add/Remove list -I am sure this is not the only file I downloaded fron th Windows update site, but there are few KB...XX... files in this text format. Below there is a pasted example of a 5KB text file from KB961118, but it is not the only format the search gave as there is another 9KB file for the KB961118 -for example- that says on its properties dialog box that it opens with Crypto extensions application, look for the abovementioned text file named KB961118.log: [KB961118.log] 1.906: ================================================================================ 1.906: 2009/02/24 21:15:43.656 (local) 1.906: C:\WINDOWS\SoftwareDistribution\Download\56f173519743089b5d285e7747238a07\update\update.exe (version 6.3.13.0) 1.906: Failed To Enable SE_SHUTDOWN_PRIVILEGE 1.922: Hotfix started with following command line: -q -z -er /ParentInfo:ef3cbfa844fa184c951055489dcd232e 1.922: In Function GetReleaseSet, line 1240, RegQueryValueEx failed with error 0x2 1.922: SP is Present 1.922: SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\SP is Equal To Specified Value 1.922: Condition succeeded for section PreReq.NDP.SP2.IsPresent in Line 1 of PreRequisite 2.266: ---- Old Information In The Registry ------ 2.266: Source:C:\WINDOWS\system32\SETC.tmp (6.0.2900.5622) 2.266: Destination:C:\WINDOWS\system32\shell32.dll (6.0.2900.5512) 2.266: ---- New Information In The Registry ------ 2.266: Source:C:\WINDOWS\system32\SETC.tmp (6.0.2900.5622) 2.266: Destination:C:\WINDOWS\system32\shell32.dll (6.0.2900.5512) 2.297: In Function GetReleaseSet, line 1240, RegQueryValueEx failed with error 0x2 2.297: SetProductTypes: InfProductBuildType=BuildType.Sel 2.297: SetAltOsLoaderPath: No section uses DirId 65701;

there are other files format. This is another example: "spuninst" in path C:\WINDOWS\$NtUninstallKB961118$\spuninst and there are many others. In order to allocate all the files, I tried to download the updates from Microsoft update web site page to a specific folder but it downloads them automatically to some location I don not know. ¿Can I search for them in other page of Microsoft? A detailed description of the procedure -including what, where and how to search for the actualization files to integrate-maybe is all I need; don't you think? -but this could be answered or shared by the true real advised only. I also make this concise question below to the same advised general public. Please someone answer the following request to this humble servant: ¿How one creates a Windows XP SP3 boot CD from a Windows XP SP2 boot CD? I tried using the ISO creation function -last option in list- in nLite but it did not work, the machine did not boot to install the OS (Windows XP SP3.) As I read in other post I have failed in burning the CD from the ISO -I extracted the ISO with PowerISO program and burned a CD with Nero7; I guess the boot files after that last extraction were not found to burn, am I wrong? Excuse my ignorance, please. Best regards, SSA
