I have recently discovered this amazing tool that has made installing windows 7 on my countless machines around the office that are used for virus detection & removal so we often wipe & reinstall our machines after a project has been completed to remove any existence of any virus's that may be lingering. Anyways my question is, after putting in the the windows key, removing & adding software from the install DVD we use the DVD to install as a trial & it comes up near the end that states windows is finalizing settings. A black box pops up stating this is not a genuine version of windows yada yada yada. This has caused a few issue's for us. Is there a way to stop the black box prompt from showing up? This is so we can have the DVD's done & issued as suited to each machine without causing concern as something that pops up at the end stating not genuine is currently preventing me from proceeding even though we have legally purchased 38 retail versions of windows 7 & we just want to slipstream the process of reinstalling. Thanks
