How to judge a driver upon Win7 is digital signed in c# ?
- Environment:win7
Target: judge whether SMBus & SMBios is digital signed as "Microsoft Hardware Compatibility Publisher"
My implement: by WMI ,Win32_PnPSignedDriver
On XP ,in Win32_PnPSignedDriver,values of SMBus & SMBios are the same as displayed on Devicemanager,"Microsoft Hardware Compatibility Publisher".
However,ON Win7 ,in Win32_PnPSignedDriver,values of SMBus & SMBios are NOT the same as displayed on Devicemanager,values are NOT Signed!!!!Truth is they are digital signed...
Does anyone who know the reason???
