Hi everyone,
I’m working on modifying the Microsoft GPU-P paravirtualization driver INF file on the guest VM to update the driver date from the legacy 6/21/2006 to the current date, hoping to resolve some identification and compatibility issues.
Steps I’ve taken:
Edited the vrd.inf file on the guest VM directly and updated the DriverVer date.
Verified the INF file on the guest shows the updated date.
Uninstalled and reinstalled the GPU-P device driver with the updated INF file.
Restarted the VM multiple times.
However, the driver date shown in Device Manager and Task Manager does not update, it still shows the old date/version.
Questions:
Are there additional INF file sections or related files I need to modify beyond just DriverVer?
Could there be cached metadata in Windows that I need to clear/reset to apply INF changes effectively?
Is there a recommended procedure or tool to properly update or rebuild the Windows driver store and ensure the VM uses the updated GPU-P driver INF?
Has anyone patched the Hyper-V GPU-P driver INF successfully and what workflow did you follow?
Any advice or pointers to detailed resources would be much appreciated!
