I installed some hardware on Windows 7 Pro, and clicked the "Always trust drivers from ..." checkbox before installing. However, now I want to disable this, i.e. I want to be prompted again. I cannot find this information on from searching on google with keywords like "windows 7" driver trust install... ugh. Can someone tell me how to do this?

I'm not 100% sure about this, but I can give you a place to start looking. My guess is that it would be in the certificate store; you can get to that by running MMC.exe and adding the "Certificates" snap in. I'm not sure if it would be in the personal or computer store (probably computer). Look through there to see if you can find the publisher of the driver (look for the publisher name, not the driver name). Let me know if you find it, I'm curious myself. =) –  Coding Gorilla Aug 13 '10 at 20:11
    
That could be it! I added the Certificates snap-in for the computer account, and under Trusted Publishers, I found an entry for the device hardware manufacturer. Thanks for the tip! I'll wait until the others get in before I delete the entry -- they might want me to wait until later to mess with this. :) In the meantime, maybe submit your answer so I can mark it when the time comes? –  Dave Aug 16 '10 at 13:05

To be properly installed in Windows 7, a hardware driver must have a Setup Information file (with the extension .inf). This is a text file that contains detailed information about the device to be installed, including the names of its driver files, the locations where they are to be installed, any required registry settings, and version information.

All devices with drivers in the DriverStore folder include Setup Information files in the %SystemRoot%\Inf folder. The basic structure of a Setup Information file is similar to an old-fashioned Windows 3.x–style .ini file. Each piece of setup information appears on its own line under a bracketed section heading. Windows will not allow the driver package to be copied into the driver store unless these sections are present and filled in correctly.

In particular, an .inf file must contain valid [SourceDisksFiles] and [SourceDisksNames] sections. At the time the .inf file is copied into the driver store, Windows creates a folder for the driver files using the name of the .inf file with an eight-character hash appended to it.

You should delete the .ini file - make a backup first.

Thanks, I'll have to try this on the next PC that comes in. –  Dave Aug 31 '10 at 12:48
