Again Thanks a lot for your quick reply but i have one more question i.e. mentioned below:
1)How generate new GUID .
2)How to change it in winpk filter after generating a new GUID :
#define FILTER_UNIQUE_NAME L”{5cbf81bd-5055-47cd-9055-a76b2b4e3697}” //unique name, quid name
Because we are using a winpk filter installer and source code is not available for compilation after doing these changes.
