Hi, 1st post so please excuse the noobiness Successfully created a multiboot DVD due to all all the exceptional postings on this forum. I have one currently unsolvable issue which hopefully someone can help with. As an OEM there is now a Microsoft program which bypasses Activation validation for OEM's wishing to download and install all MS critical patches etc for the end users PC before delivery to them. It saves having to temporarily activate etc and works exceptionally well, particularly after slipstreaming Ryan's update pack into our install. Currently I have it set in under a GuiRunOnce batch file in my Winnt.sif. Problem is that it runs at around T12 which is far too early as Windows isn't installed fully at this stage. I've tried under a RunOnceEx.exe format but that runs for the end user as well as us and we don't want that too happen. Where or what do I need to do to have it only run on our install routine only and not an end user? Perhaps around T35 or so. Also I have the same issue with the Microsoft Interactive Training module that needs to be installed as part of the OEM preinstall routine. When I had it as part of GuiRunOnce command I received an error once Windows had finished installing and on the first boot that Windows couldn't find "logon.bat" which is the batch file I ran to install Interactive training. It is obviously deleted on first boot. I check and it hasn't been installed earlier obviously due to the GuiRunOnce coming in too early. thanks for any assistance forthcoming regards Greg
