MsiEnumPatchesEx() would be the correct way. If you're a C# addict you'd need to p/invoke. There are probably WMI equivalents somewhere too, but I think that's Win32_Patch, not QFE.

The execution of the patch succeedes and i can see an new entry in the software update list under windows7. Now i want to search the installed patch via an application written in C#. I've tried to search the patch via an query to the Win32_QickFixEngineering class with no result. A search to the Registry to the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ path brings no result except the base software version. Can someone please point me to right direction where to search further.
