I have a computer running Windows Server 2003 x86 which is offering a suspicious Windows Update.
The title of the update is
Microsoft Corporation - Other Hardware - Microsoft UAA Bus Driver for High Definition Audio.
The description is (Exact copy-paste; it doesn't have any links)
Size: 77 KB microsoft system software update released on March 05 2004.
In Device Manager, I have such a device listed under System Devices, and it's working properly. If I click Update Drivers, it starts downloading a driver from Windows Update (which I cancelled)
Does anyone know what this is, and why it's so different from normal updates? (No link, no capitalization in Details)
