Hi I can confirm this. Integrated b5508 into RTM source applied some tweaks, removed components and changed "WINDOWS" to"WINXP" - but it was still WINDOWS. Changing the "Documents and Settings" path to "Docs" went fine. Moreover most tweaks did not work...e.g. show known file extensions. Integrated IE7 and it works but the quicklauch icon of IE and the show desktop is gone, this is the first time since many installs. setuperr.log is empty, this was the ini -> LETZTE_SESSION.INI
