I have tried my iso, well no bugs , but after I visited Windows Update, I needed to install some critical updates from .net framework 2 namely # ▼. NDP20SP2-KB958481-x64.exe . 19,282,272 . Application Compatibility Update # ▼. NDP20SP2-KB2656352-x64.exe 13,096,048 . MS11-100 - ASP.NET # ▼. NDP20SP2-KB2729450-x64.exe 31,280,648 . MS12-074 - 4 Vulnerabilities fixed # ▼. NDP20SP2-KB2742596-x64.exe 20,742,168 . MS13-004 - 4 Vulnerabilities fixed # ▼. NDP20SP2-KB2789643-x64.exe 11,963,400 . MS13-015 - XAML Browser Applications (XBAPs) However, I misinterpreted the tutorial, because I though that after installing .net framework 3.5 I didn't need any update from .net framework 2.0, like if .net 3.5 had a cumulative update that included everything that was left behind that version, well I need to rebuild my iso, to make it perfect, but if Windows Update does this job for me manually there's no big problem here. Another Issue, on the batch file the desktop search 4 is under Folder Addon, and I skip that, I pasted on the RunOnce folder, so another manually install, no problem (requires path file fix) So I only need to add 5 files to the Runonce Folder, and fix the path file for the desktop search, and I have a perfect XP x64 fully updated. Just another thing as a remark, this is extremely boring and time consuming, it takes forever to install the XP on a system more than a hour and something but on the other hand you have a perfect system fully updated on your finger tips.
