Thank you for the fast reply! This night, i have read the the guide at vorck.com more than 10 times... And i have not found a "instructions.txt"... (Deep-Link?) If i right, i need this 3 "FDV"-files 1. SFC.DLL 2. SETUPAPI.DLL 3. SFCFILES.DLL And there are two ways to handle it... - use hacked SFC.DLL , hacked SETUPAPI.DLL and original SFCFILES.DLL or - use original SFC.DLL, hacked SETUPAPI.DLL and modified (empty) SFCFILES.DLL (i will prefer this way...) Ok at this point? Now, there are two questions left... - Where i have to (re)place the files? In the i386-folder of my Win2k-SP4-CD? Or in the i386-folder of the expanded SP4-Pack before slipstreaming? (so i understand the guide at vorck.com)(i think its pretty much the same...) - Which files do i need from the XPSP1-CD? I have found nothing about the XP-files... many regards XiLeeN
