I always value your opinion. actually some slipstreming changes sysoc.inf plain cd and after xpc are different the newer one has DriverVer=07/01/2001,5.1.2600.1106 instead of DriverVer=07/01/2001,5.1.2600.0 and WMAccess=ocgen.dll,OcEntry,wmaccess.inf,,7 OEAccess=ocgen.dll,OcEntry,oeaccess.inf,,7 WMPOCM=ocgen.dll,OcEntry,wmpocm.inf,,7 TabletPC=tabletoc.dll,TabletSetupProc,Tabletpc.inf,HIDE,7 that the original doesn't have. I'll save the HIDE the modifications in a file and inject them in the source before XPC runs. We'll see if it works. Thank you
