K lets start fresh... Yes i replaced those files and the crashes where gone. As for the switches : XPize.exe /S /norestore /noboot /nologon /noscreen /nowall /notask norestore = working noboot = working nologon = working noscreen = working notask working nowall = dont work After this i have still the wallpaper, but the taskbar is still windows default, and also are the icons.
