Description:
Ever since the agents were upgraded to Windows 7/Windows 2008 the list of Windows updates (KB....) within the Inventory > Operating System > System Updates on some of them is empty or the tree is not listed at all.
Solution:
Previously the list of Windows Updates was obtained from the registry key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\HotFix
With the introduction of Windows 7 and Windows 2008, this has changed.
The list is now obtained by running 'wmic qfe list full'
On some PCs this returns an empty list: "No instances availabe" although Windows updates have been applied.
This is described in more detail in:

The described solution, http://support.microsoft.com/kb/947821, takes care of the problem with the wmic command and will also cause the System
Updates to show up after the next AM agent run.
