This is a general question because I am having issues installing some software and windows is complaining that the drivers are not signed.
When installing a program does windows check that all files are digitally signed or just certain file extensions associated with drivers? EXE, SYS, DLL, INF, OCX, VXD
Does windows only allow digital signatures from Microsoft or is a valid signature from any company accepted? I ran sigverif and all my drivers are signed by Microsoft which means there has been some testing from Microsoft.
What is the easiest method to verify if a file is digitally signed and if windows should be allowing the files to be used in the installation? Since the files are not allowed to be installed I don't see how sigverif could be used.
What is the default action in Windows for unsigned files?
