List of Installed Updates on Windows 7 C#

With Microsoft Ultimate Wisdom they have changed the location of updates from Registry. I can get the updates from W开发者_如何学JAVAindows 2003 Servers no problem. Its just that Windows 7 is no longer in:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

Any body got any other ways to get it. Preferably in C# or using WMI?

God Save Microsoft with their Wisdom

For Window 7 64-bit it's in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Updates
