Have you seen this? From Windows Standalone Update Installer: "Update for Microsoft Windows (KB2976978) is required by your computer and cannot be uninstalled."
I got this in three scenarios:
1) Pulled Windows 8.1 ISO from Microsoft, tried to uninstall KB2976978.
2) Restored Dell System Recovery image, tried to uninstall KB2976978.
3) Installed an old DVD of Windows 8.1 (pre Update), tried to uninstall KB2976978.
In the first two cases, I could imagine that either the update was streamed into the install.wim/install.esd and couldn't be removed or Disk Cleanup was run, eliminating the old files. From searching, I read that "Microsoft does this for all servicing stack updates" but this is the first I've run into it.
Also, extra points for finding this?
