I have been trying to work out how to silently installing printers on Windows XP and have created a batch file that does the following @echo off color 4e cls echo Installing Printers regedit /S ignoredriversigning.reg cd "\Drivers\Printers\Kyocera\Win2K_XP\" echo IT Dept Printer C:\WINDOWS\system32\rundll32.exe C:\WINDOWS\system32\printui.dll,PrintUIEntry /w /b "FS3800" /x /n "part of the n switch" /if /f "Z:\Drivers\Printers\Kyocera\Win2K_XP\oemsetup.inf" /r "http://10.10.10.10:631/printers/KyFS3800" /m "Kyocera Mita FS-3800 KX" rem a bunch of other printer install stings regedit /S warnaboutdrivers.reg while the reg files contain Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Driver Signing] "Policy"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Driver Signing] "Policy"=hex:00 [HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows NT\Driver Signing] "BehaviorOnFailedVerify" = dword:00000000 (the activate one has "1" values However when installing the Kyocera Mita drivers i still get the message telling me the drivers havn't passed the windows logo testing programme, how can I surpress these, and where am i going wrong? Everything works apart from having to allow each driver in turn. (n.b. paths and names changed for security, the reg files have fully qualiifed paths)
