Today I noticed when I go into the control panel > Programs > Programs and features > Installed updates I wait about 2 mins for the updates to appear only to be met with 'No updates are installed on this computer'. I then tried taking a look via WMI and found that when I run Select * from win32_QuickFixEngineering I get 0 results returned.
I'm not sure why I can't see anything from the control panel nor access it via a WMI query. Other test systems were able to view installed updates and can use WMI to see what updates are installed.
